The GRP provides complete interconnectivity between all of these elements. The ispLSI 1048EA features 5V in-system programmability and in-system diagnostic capabilities via IEEE 1149.1 Test Access Port. The ispLSI 1048EA offers non-volatile reprogrammability of the logic, as well as the interconnect to provide truly reconfigurable systems. A functional superset of the ispLSI 1048 architecture, the ispLSI 1048EA device adds user selectable 3.3V or 5V I/O and open-drain output options. * IN-SYSTEM PROGRAMMABLE -- Increased Manufacturing Yields, Reduced Time-toMarket and Improved Product Quality -- Reprogram Soldered Devices for Faster Prototyping * OFFERS THE EASE OF USE AND FAST SYSTEM SPEED OF PLDs WITH THE DENSITY AND FLEXIBILITY OF FIELD PROGRAMMABLE GATE ARRAYS -- Complete Programmable Device Can Combine Glue Logic and Structured Designs -- Enhanced Pin Locking Capability -- Four Dedicated Clock Input Pins -- Synchronous and Asynchronous Clocks -- Programmable Output Slew Rate Control to Minimize Switching Noise -- Flexible Pin Placement -- Optimized Global Routing Pool Provides Global Interconnectivity U SE is p The basic unit of logic on the ispLSI 1048EA device is the Generic Logic Block (GLB). The GLBs are labeled A0, A1...F7 (see Figure 1). There are a total of 48 GLBs in the ispLSI 1048EA device. Each GLB has 18 inputs, a programmable AND/OR/Exclusive OR array, and four outputs which can be configured to be either combinatorial or registered. Inputs to the GLB come from the GRP and dedicated inputs. All of the GLB outputs are brought back into the GRP so that they can be connected to the inputs of any other GLB on the device.

Four dedicated clock pins (Y0, Y1, Y2 and Y3) are brought into the distribution network, and five clock outputs (CLK 0, CLK 1, CLK 2, IOCLK 0 and IOCLK 1) are provided to route clocks to the GLBs and I/O cells. The Clock Distribution Network can also be driven from a special clock GLB (D0). The logic of this GLB allows the user to create an internal clock from a combination of internal signals within the device. U SE is The device also has 96 I/O cells, each of which is directly connected to an I/O pin. Each I/O cell can be individually programmed to be a combinatorial input, registered input, latched input, output or bi-directional I/O pin with 3-state control. The signal levels are TTL compatible voltages and the output drivers can source 2mA or sink 8mA. Each output can be programmed independently for fast or slow output slew rate to minimize overall output switching noise. By connecting the VCCIO pin to a common 5V or 3.3V power supply, I/O output levels can be matched to 5V or 3.3V compatible voltages. Programmable Open-Drain Outputs In addition to the standard output configuration, the outputs of the ispLSI 1048EA are individually programmable, either as a standard totem-pole output or an open-drain output. The totem-pole output drives the specified Voh and Vol levels, whereas the open-drain output drives only the specified Vol. The Voh level on the open-drain output depends on the external loading and pull-up. This output configuration is controlled by a programmable fuse. The default configuration when the device is in bulk erased state is totem-pole configuration. The open-drain/totem-pole option is selectable through the Lattice software tools. Eight GLBs, 16 I/O cells, dedicated inputs (if available) and one ORP are connected together to make a Megablock (Figure 1). The outputs of the eight GLBs are connected to a set of 16 universal I/O cells by the ORP. Each ispLSI 1048EA device contains six Megablocks. The GRP has, as its inputs, the outputs from all of the GLBs and all of the inputs from the bi-directional I/O cells. All of these signals are made available to the inputs of the GLBs. Delays through the GRP have been equalized to minimize timing skew. 2 Specifications ispLSI 1048EA Boundary Scan Figure 2.

These values are for estimates only. Since the value of Icc is sensitive to operating conditions and the program in the device, the actual Icc should be verified. 0127/1048EA Package Thermal Characteristics For the ispLSI 1048EA-170, it is strongly recommended that the actual Icc be verified to ensure that the maximum junction temperature (TJ) with power supplied is not exceeded. Depending on the specific logic design and clock speed, airflow may be required to satisfy the maxi- mum allowable junction temperature (TJ) specification. Please refer to the Thermal Management section of the Lattice Semiconductor Data Book or CD-ROM for additional information on calculating TJ. 10 Specifications ispLSI 1048EA Pin Description PQFP / TQFP PIN NUMBERS 22, 28, 35, 41, 53, 59, 67, 73, 86, 92, 99, 105, 118, 124, 3, 9, GOE0, GOE1 64, 114 20 TMS 46 TDO 50 TCK 78 RESET 19 Y0 15 Y1 83 Y2 80 Y3 79 GND VCC VCCIO DESCRIPTION 26, 32, 39, 45, 57, 63, 71, 77, 90, 96, 103, 109, 122, 128, 7, 13 Input/Output Pins - These are the general purpose I/O pins used by the logic array.
