3 SmartFusion2 SoC FPGA Feature
Description
The following figure shows the SmartFusion2 SoC FPGA chip layout with various components of the
FPGA highlighted.
Figure 3 • SmartFusion2 SoC FPGA Chip Layout
The following sections provide detailed information about the security, reliability, power, and performance
features supported by SmartFusion2 SoC FPGAs. Reliability
SmartFusion2 flash-based fabric has zero FIT configuration rate due to its SEU immunity, which is critical
in reliability applications. The flash fabric also has the advantage that no external configuration memory
is required, making the device instant-on; it retains configuration when powered off. To complement this
unique FPGA capability, SmartFusion2 devices add reliability to many other aspects of the device. Single
error correct double error detect (SECDED) protection is implemented on the Cortex-M3 embedded
scratch pad memory, Ethernet, CAN, and USB buffers, and is optional on the DDR memory controllers.
This means that if a one-bit error is detected, the error is corrected automatically. If errors of more than
one bit are detected, they are not corrected. SECDED error signals are brought to the FPGA fabric to
allow the user to monitor the status of these protected internal memories. Other areas of the architecture
are implemented with latches, which are more resistant to SEUs. Therefore, no correction is needed in
DDR bridges (MSS, MDDR, and FDDR), instruction cache and MMUART, SPI, and PCIe FIFOs.

3.1 Highest Security Devices
Building further on the intrinsic security benefits of flash nonvolatile memory technology, the
SmartFusion2 family incorporates all the legacy security features that made the original SmartFusion®,
Fusion®, IGLOO®, and ProASIC®3 third-generation flash FPGAs and cSoCs the gold standard for
secure devices in the PLD industry. In addition, the fourth-generation flash-based SmartFusion2 SoC
FPGAs add many unique design security features, data security features, and use models new to the
PLD industry.
3.1.1 Design Security vs. Data Security
When classifying the security attributes of programmable logic devices (PLDs), a useful distinction is
made between design security and data security.
3.1.2 Design Security
Design security protects the intent of the owner of the design such as keeping the design and associated
bitstream keys confidential, preventing design changes (for example, insertion of Trojan Horses), and
controlling the number of copies made throughout the device life cycle. Design security may also be
known as intellectual property (IP) protection. It is one aspect of anti-tamper (AT) protection. Design
security applies to the device from initial production, includes any updates such as in-the-field upgrades,
and can include decommissioning of the device at the end of its life, if desired. Good design security is a
prerequisite for good data security.
The following table lists the design security features supported in various SmartFusion2 devices. Blank
cells indicate that the feature is not supported.

3.1.3 Data Security
Data security is protecting the information the FPGA is storing, processing, or communicating in its role in
the end application. If, for example, the configured design is implementing the key management and
encryption portion of a secure military radio, data security could entail encrypting and authenticating the
radio traffic, and protecting the associated application-level cryptographic keys. Data security is closely
related to the terms information assurance (IA) and information security. All SmartFusion2 devices
incorporate enhanced design security, making them the most secure programmable logic devices ever
made. Select SmartFusion2 models also include an advanced set of on-chip data security features that
make designing secure information assurance applications easier and better than ever before.
The following table lists the data security features supported in various SmartFusion2 devices. Blank

SmartFusion2 SoC FPGA Feature Description
Microsemi Proprietary and Confidential PB0115 Product Brief Revision 27.0 21
3.2 Low Power
Microsemi’s flash-based FPGA fabric results in extremely low-power design implementation with static
power as low as 7.5 mW for 6,060 LE devices. Flash*Freeze technology provides an ultra-low power
static mode (Flash*Freeze mode) for SmartFusion2 devices with power less than 11 mW for the largest
device that contains146,124 logic elements. Flash*Freeze mode entry retains all the SRAM and register
information, and the exit from Flash*Freeze mode achieves rapid recovery to active mode.
3.3 High-Performance FPGA Fabric
Built on 65 nm process technology, the SmartFusion2 SoC FPGA fabric is composed of four building
blocks such as the logic module, the large SRAM, the micro SRAM, and the mathblock. The logic module
is the basic logic element and has advanced features:
• A fully permutable 4-input LUT optimized for lowest power
• A dedicated carry chain based on carry look-ahead technique
• A separate flip-flop which can be used independently from the LUT
The 4-input LUT can be configured either to implement any 4-input combinatorial function or to
implement an arithmetic function where the LUT output is XORed with carry input to generate the sum
output.
3.3.1 Dual-Port Large SRAM
Large SRAM (LSRAM) (RAM1Kx18) is targeted for storing large memory for use with various operations.
Each LSRAM block can store up to 18,432 bits. Each RAM1Kx18 block contains two independent data
ports such as Port A and Port B. LSRAM is synchronous for both read and write operations. Operations
are triggered on the rising edge of the clock. The data output ports of the LSRAM have pipeline registers
which have control signals that are independent of the SRAM’s control signals.
3.3.2 Three-Port Micro SRAM
SRAM(RAM64x18) is the second type of SRAM, which is embedded in the fabric of SmartFusion2
devices. RAM64x18 uSRAM is a 3-port SRAM; Port A and Port B are used as read ports and Port C is
used as write port. The two read ports are independent of each other and can perform read operations in
both synchronous and asynchronous modes. The write port is always synchronous. The uSRAM block is
approximately 1 KB (1,152 bits) in size. These uSRAM blocks are primarily targeted for building
embedded FIFOs to be used by any embedded fabric masters.
3.3.3 Mathblocks for DSP Applications
The fundamental building block in any digital signal processing algorithm is the MACC function.
SmartFusion2 SoC FPGAs implement a custom 18 x 18 MACC block for efficient implementation of
complex DSP algorithms such as finite impulse response (FIR) filters, infinite impulse response (IIR)
filters, and fast fourier transform (FFT) for filtering and image processing applications.
Each mathblock has the following capabilities:
• Supports 18 x 18 signed multiplications natively (A[17:0] x B[17:0])
• Supports dot product; the multiplier computes:
• (A[8:0] x B[17:9] + A[17:9] x B[8:0]) x 29
• Built-in addition, subtraction, and accumulation units to combine multiplication results efficiently
In addition to the basic MACC function, DSP algorithms typically need small amounts of RAM for
coefficients and larger RAMs for data storage. SmartFusion2 micro RAMs are ideally suited to serve the
needs of coefficient storage while the large RAMs are used for data storage.
3.4 Microcontroller Subsystem
The microcontroller subsystem (MSS) contains a high-performance integrated Cortex-M3 processor,
running at up to 166 MHz. The MSS contains an 8 Kbyte instruction cache to provide low latency access
to internal eNVM and external DDR memory. The MSS provides multiple interface options to the FPGA
fabric in order to facilitate tight integration between the MSS and user logic in the fabric.
SmartFusion2 SoC FPGA Feature Description
Microsemi Proprietary and Confidential PB0115 Product Brief Revision 27.0 22
3.4.1 ARM Cortex-M3 Processor
The MSS uses the latest revision (r2p1) of the ARM Cortex-M3 processor. Microsemi’s implementation
includes the optional embedded trace macrocell (ETM) features for easier development and debug and
the memory protection unit (MPU) for real-time operating system support.
3.4.2 Cache Controller
To minimize latency for instruction fetches when executing firmware out of off-chip DDR or on-chip
eNVM, an 8 Kbyte, 4-way set associative instruction cache is implemented. This provides zero wait state
access for cache hits and is shared by both I and D code buses of the Cortex-M3 processor. In the event
of cache misses, cache lines are filled, replacing existing cache entries based on a least recently used
(LRU) algorithm.
There is a configurable option available to operate the cache in a locked mode, whereby a fixed segment
of code from either the DDR or eNVM is copied into the cache and locked there, so that it is not replaced
when cache misses occur. This would be used for performance-critical code.
It is also possible to disable the cache altogether, which is desirable in systems requiring very
deterministic execution times.
The cache is implemented with SEU tolerant latches.
3.4.3 DDR Bridge
The DDR bridge is a data bridge between four AHB bus masters and a single AXI bus slave. The DDR
bridge accumulates AHB writes into write combining buffers prior to bursting out to external DDR
memory. The DDR bridge also includes read combining buffers, allowing AHB masters to efficiently read
data from the external DDR memory from a local buffer. The DDR bridge optimizes reads and writes from
multiple masters to a single external DDR memory. Data coherency rules between the four masters and
the external DDR memory are implemented in hardware. The DDR bridge contains three write
combining / read buffers and one read buffer. All buffers within the DDR bridge are implemented with
SEU tolerant latches and are not subject to the single event upsets (SEUs) that SRAM exhibits.
SmartFusion2 devices implement three DDR bridges in the MSS, FDDR, and MDDR subsystems.
3.4.4 AHB Bus Matrix
The AHB bus matrix (ABM) is a non-blocking, AHB-Lite multi-layer switch, supporting 10 master
interfaces and 7 slave interfaces. The switch decodes access attempts by masters to various slaves,
according to the memory map and security configurations. When multiple masters are attempting to
access a particular slave simultaneously, an arbiter associated with that slave decides which master
gains access, according to a configurable set of arbitration rules. These rules can be configured by the
user to provide different usage patterns to each slave. For example, a number of consecutive access
opportunities to the slave can be allocated to one particular master, to increase the likelihood of same
type accesses (all reads or all writes), which makes more efficient usage of the bandwidth to the slave.
3.4.5 System Registers
The MSS system registers are implemented as an AHB slave on the AHB bus matrix. This means the
Cortex-M3 processor or a soft master in the FPGA fabric may access the registers and therefore control
the MSS. The system registers can be initialized by user-defined flash configuration bits on power-up.
Each register also has a flash bit to enable write protecting the contents of the registers. This allows the
MSS system configuration to be reliably fixed for a given application.
3.4.6 Fabric Interface Controller
The fabric interface controller (FIC) block provides two separate interfaces between the MSS and the
FPGA fabric such as the MSS master (MM) and fabric master (FM). Each of these interfaces can be
configured to operate as AHB-Lite or APB3. Depending on device density, there are up to two FIC blocks
(FIC_0 and FIC_1) present in the MSS.
SmartFusion2 SoC FPGA Feature Description
Microsemi Proprietary and Confidential PB0115 Product Brief Revision 27.0 23
3.4.7 Embedded SRAM
The MSS contains two blocks of 32 KB embedded SRAM (eSRAM), giving a total of 64 KB. Having the
eSRAM arranged as two separate blocks allows the user to take advantage of the Harvard architecture
of the Cortex-M3 processor. For example, code could be located in one eSRAM, while data, such as the
stack, could be located in the other.
The eSRAM is designed for SECDED protection. When SECDED is disabled, the SRAM usually used to
store SECDED data may be reused as an extra 16 KB of eSRAM.
3.4.8 Embedded NVM
The MSS contains up to 512 KB of embedded NVM (eNVM) (64 bits wide). Accesses to the eNVM from
the Cortex-M3 processor are cacheable.
3.4.9 DMA Engines
Two DMA engines are present in the MSS such as high-performance DMA and peripheral DMA.
3.4.9.1 High-Performance DMA
The high-performance DMA (HPDMA) engine provides efficient memory to memory data transfers
between an external DDR memory and internal eSRAM. This engine has two separate AHB-Lite
interfaces—one to the MDDR bridge and the other to the AHB bus matrix. All transfers by the HPDMA
are full word transfers.
3.4.9.2 Peripheral DMA
The peripheral DMA engine (PDMA) is tuned for offloading byte-intensive operations, involving MSS
peripherals, to and from the internal eSRAMs. Data transfers can also be targeted to user logic/RAM in
the FPGA fabric.
3.4.10 APB Configuration Bus
Each SmartFusion2 device has an APB configuration bus that allow the user to initialize the SerDes
ASIC blocks, the fabric DDR memory controller, and user instantiated peripherals in the FPGA fabric.
3.4.11 Peripherals
A large number of communications and general purpose peripherals are implemented in the MSS.
3.4.11.1 USB Controller
The MSS contains a high speed USB 2.0 on-the-go (OTG) controller with the following features:
• Operates either as the function controller of a high-speed / full-speed USB peripheral or as the
host/peripheral in point-to-point or multi-point communications with other USB functions.
• Complies with the USB 2.0 standard for high-speed functions and with the On-The-Go supplement
to the USB 2.0 specification.
• Supports OTG communications with one or more high-speed, full-speed, or low-speed devices.
3.4.11.2 Triple Speed Ethernet MAC
The triple speed Ethernet (TSE) MAC supports IEEE 802.3 10/100/1000 Mbps Ethernet operation. The
following PHY interfaces are directly supported by the MAC:
•GMII
•MII
•TBI
The Ethernet MAC hardware implements the following functions:
• 4 KB internal transmit FIFO and 8 KB internal receive FIFO
• IEEE 802.3X full-duplex flow control
• DMA of Ethernet frames between internal FIFOs and system memory (such as eSRAM or DDR)
• Cut-through operation
• SECDED protection on internal buffers

Microsemi Proprietary and Confidential PB0115 Product Brief Revision 27.0 24
3.4.11.3 SGMII PHY Interface
SGMII mode is implemented by means of configuring the MAC for 10-bit interface (TBI) operation,
allocating one of the high-speed serial channels to SGMII, and by implementing custom logic in the
fabric.
3.4.11.4 10 Gbps Ethernet
Support for 10 Gbps Ethernet is achieved by programming the SerDes interface to XAUI mode. In this
mode, a soft 10G EMAC with XGMII interface can be directly connected to the SerDes interface.
3.4.11.5 Communication Block
The communication block (COMM_BLK) provides a UART-like communications channel between the
MSS and the system controller. System services are initiated through the COMM_BLK.
3.4.11.6 Serial Peripheral Interface
The serial peripheral interface (SPI) controller is compliant with the Motorola SPI, Texas Instruments
synchronous serial, and National Semiconductor MICROWIRE formats. In addition, the SPI supports
interfacing to large SPI flash and EEPROM devices by way of the slave protocol engine. The SPI
controller supports both master and slave modes of operation.
The SPI controller embeds two 4 x 32 (depth x width) FIFOs for receive (Rx) and transmit (Tx) data.
These FIFOs are accessible through Rx data and Tx data registers. Writing to the Tx data register
causes the data to be written to the transmit FIFO. This is emptied by transmit logic. Similarly, reading
from the Rx data register causes data to be read from the receive FIFO.
3.4.11.7 Multi-Mode UART
SmartFusion2 devices contain two identical multi-mode universal asynchronous/synchronous
receiver/transmitter (MMUART) peripherals that provide software compatibility with the popular 16550
device. They perform serial-to-parallel conversion on data originating from modems or other serial
devices, and perform parallel-to-serial conversion on data from the Cortex-M3 processor to these
devices. The following are the main features supported:
• Fractional baud rate capability
• Asynchronous and synchronous operation
• Full programmable serial interface characteristics
• Data width is programmable to 5, 6, 7, or 8 bits
• Even, odd, or no-parity bit generation/detection
• 1,1½, and 2 stop bit generation
• 9-bit address flag capability used for multidrop addressing topologies
3.4.11.8 I2C
SmartFusion2 devices contain two identical master/slave I2C peripherals that perform serial-to-parallel
conversion on data originating from serial devices, and perform parallel-to-serial conversion on data from
the ARM Cortex-M3 processor, or any other bus master, to these devices. The following are the main
features supported:
•I
2C v2.1
• 100 Kbps
• 400 Kbps
• Dual-slave addressing
•SMBus v2.0
•PMBus v1.1
3.5 Clock Sources
SmartFusion2 devices have two on-chip RC oscillators—a 1 MHz RC oscillator and a 50 MHz RC
oscillator—and up to two main crystal oscillators (32 kHz–20 MHz). These are available to the user for
generating clocks to the on-chip resources and the logic built on the FPGA fabric array. The second
crystal oscillator available on the SmartFusion2 devices is dedicated for RTC clocking. These oscillators
(except the RTC crystal oscillator) can be used in conjunction with the integrated user phase-locked
SmartFusion2 SoC FPGA Feature Description
Microsemi Proprietary and Confidential PB0115 Product Brief Revision 27.0 25
loops (PLLs) and fabric clock conditioning circuits (FAB_CCC) to generate clocks of varying frequency
and phase. In addition to being available to the user, these oscillators are also used by the system
controller, power-on reset circuitry, MSS during Flash*Freeze mode, and the RTC.
SmartFusion2 devices have up to eight fabric CCC (FAB_CCC) blocks and a dedicated PLL associated
with each CCC to provide flexible clocking to the FPGA fabric portion of the device. The user has the
freedom to use any of the eight PLLs and CCCs to generate the fabric clocks and the internal MSS clock
from the base fabric clock (CLK_BASE). There is also a dedicated CCC block for the MSS (MSS_CCC)
and an associated PLL (MPLL) for MSS clocking and de-skewing the CLK_BASE clock. The fabric
alignment clock controller (FACC), part of the MSS CCC, is responsible for generating various aligned
clocks required by the MSS for correct operation of the MSS blocks and synchronous communication
with the user logic in the FPGA fabric.
3.6 High-Speed Serial Interfaces
3.6.1 SerDes
SmartFusion2 has up to four 5-Gbps SerDes transceivers, each supporting four SerDes lanes.
The native EPCS SerDes interface facilitates the implementation of SRIO in the fabric or an SGMII
interface for the Ethernet MAC in the MSS. In EPCS mode, the transceiver runs at a maximum rate of
3.2 Gbps.
3.6.2 PCI Express
PCI express (PCIe) is a high speed, packet-based, point-to-point, low pin count, and serial interconnect
bus. The SmartFusion2 family has two hard high-speed serial interface blocks. Each SerDes block
contains a PCIe system block. The PCIe system is connected to the SerDes block and following are the
main features supported:
• Supports ×1, ×2, and ×4 lane configuration
• Endpoint configuration only
• PCI Express Base Specification Revision 2.0
• 2.5 and 5.0 Gbps compliant
• Embedded receive (2 KB), transmit (1 KB) and retry (1 KB) buffer dual-port RAM implementation
• Maximum payload size of up to 256 bytes
• 64-bit AXI or 32-bit AHB-Lite Master and Slave interface to the application layer
• 32-bit APB interface to access configuration and status registers of PCIe system
• Up to 3 × 64 bit base address registers
• 1 virtual channel (VC)
3.6.3 XAUI/XGXS
The XAUI/XGXS extension allows the user to implement a 10 Gbps (XGMII) Ethernet PHY interface by
connecting the Ethernet MAC fabric interface through an appropriate soft IP block in the fabric.
3.7 High-Speed Memory Interfaces: DDRx Memory
Controllers
There are up to three DDR subsystems, MDDR (MSS DDR), and FDDR (fabric DDR) present in
SmartFusion2 devices. Each subsystem consists of a DDR controller, PHY, and a wrapper. The MDDR
has an interface from the MSS and fabric, and FDDR provides an interface from the fabric.
The following are the main features supported by the FDDR and MDDR:
• Support for LPDDR, DDR2, and DDR3 memories
• Simplified DDR command interface to standard AMBA AXI/AHB interface
• Up to 667 Mbps (333 MHz double data rate) performance
• Supports 1, 2, or 4 ranks of memory
• Supports different DRAM bus width modes: x8, x9, x16, x18, x32, and x36
• Supports DRAM burst length of 2, 4, or 8 in full bus-width mode; supports DRAM burst length of 2, 4,
8, or 16 in half bus-width mode
SmartFusion2 SoC FPGA Feature Description
Microsemi Proprietary and Confidential PB0115 Product Brief Revision 27.0 26
• Supports memory densities up to 4 GB
• Supports a maximum of 8 memory banks

• Supports data reordering, returning critical word first for each command
3.7.1 MDDR Subsystem
The MDDR subsystem has two interfaces to the DDR. One is an AXI 64-bit bus from the DDR bridge
within the MSS. The other is a multiplexed interface from the FPGA fabric, which can be configured as
either a single AXI 64-bit bus or two 32-bit AHB-Lite buses. There is also a 16-bit APB configuration bus,
which is used to initialize the majority of the internal registers within the MDDR subsystem after reset.
This APB configuration bus can be mastered by the MSS directly or by a master in the FPGA fabric.
Support for 3.3 V Single Data Rate DRAMs (SDRAM) can be obtained by using the SMC_FIC interface
in the MDDR subsystem. Users would then instantiate a soft AHB or AXI SDRAM memory controller in
the FPGA fabric and connect I/O ports to 3.3 V MSIO.
3.7.2 FDDR Subsystem
The FDDR subsystem has one interface to the DDR. This is a multiplexed interface from the FPGA
fabric, which can be configured as either a single AXI 64-bit bus or two 32-bit AHB-Lite buses. There is
also a 16-bit APB configuration bus, which is used to initialize the majority of the internal registers within
the FDDR subsystem after reset. This APB configuration bus can be mastered by the MSS or a master in
the FPGA fabric.
