24 + 2 10/100/1000 ETHERNET SWITCH WITH EMBEDDED
MANAGEMENT PROCESSOR
OVERVIEW:
The StreamPack L64324 is a single chip 24-port Fast Ether net (10/100)
switch with two Gigabit uplinks and an embedded ARM7®processor. This
device is based on LSI Logic’s industr y proven E110 MAC, ARM7 and E1000
MAC cores. Each port contains the Layer-2 Front End - 10/100 MAC, Tx and
Rx FIFOs, flow control (IEEE 802.3x), priority queuing (IEEE 802.1p) and VLAN
(IEEE 802.1Q). The L64324 non-blocking wire-speed switch fabric can sustain
packet transfers of over 13 Mpps. The StreamPack L64324 internal MAC
address table holds over 4,000 entries. The embedded ARM7®processor, with
4K unified Instruction and Data cache, may be utilized for network manage-
ment related tasks. A 96-bit SDRAM controller at 125 MHz provides up to 12
Gbps in memor y bandwidth for packet processing. Two Gigabit uplinks provide
connectivity to the backbone or local ser ver farm. This device allows trunking of
up to four of the 10/100 ports, or two of the 2-Gigabit uplink por ts to provide
higher aggregated bandwidth of up to 800 Mbps or 4 Gigabits respectively,
with added data integrity. The StreamPack L64324 priority queuing capability
allows for time sensitive data to have access to the network with minimal delay.
The Serial MII (SMII) enables a lower I/O density package interfacing the phys-
ical layer devices to the StreamPack L64324 in a 388 PBGA package. This
System-On-a-Chip (SOC) solution enables system designers to develop cost-
effective desktop and workgroup fully-managed or partially managed Fast
Ethernet switches. StreamPack L64324 is fabricated using LSI Logic’s 0.25
micron process technology with the core logic operating at 2.5V.

DEVELOPMENT ENVIRONMENT:
LSI Logic offers a comprehensive System Development Platform (SDP) BD-
EVAL64324 to facilitate evaluation, and perfor mance analysis of the
StreamPack. The development system consists of a functional Layer 2 switch,
product documentation, schematic, BOM, Gerber file and UNH certified
firmware specifically designed to take advantage of the StreamPack L64324
features. This enables the network equipment designers to reduce the overall
design and product development cycle.
APPLICATIONS:
StreamPack L64324 can be used for the design of numerous Ethernet
applications such as managed or semi managed 12 to 48 10/100 Ethernet
ports with Gigabit uplinks option. In a control plane application, the L64324
offers a cost-effective communication between the blades in a modular switch.
The StreamPack L64324 Gigabit uplinks are equipped with GMII for copper
interface and TBI (Ten Bit Inter face) for Fiber connections.
