512K x 32 SSRAM / 1M x 64 SDRAM

EXTERNAL MEMORY SOLUTION FOR LUCENT’S LUCTAPC640 ATM PORT CONTROLLER

FEATURES

DESCRIPTION

The WED9LAPC3C16V8BC is a 3.3V, 512K x 32

Synchronous Pipeline SRAM and a 1M x 64 Synchronous

DRAM array packaged in a 21mm x 21mm 192 lead

BGA.

ꢀ

Clock speeds:

• SSRAM: 100 MHz

• SDRAM: 100 MHz

ꢀ

100% tested to timing requirements of

LUCTAPC640’s memory interface

The WED9LAPC3C16V8BC provides the memory

required for the CRAM (Control Memory) and VCRAM

(Virtual Connection Memory) memory ports for Lucent’s

LUCTAPC640ATM port controller. When used in conjunction

with the WED9LAPC2B16P8BC, which provides memory for

the BRAM (Buffer Memory) and PRAM (Pointer Memory)

memory ports, the entire memory requirement of the

LUCTAPC640 can be met using these 2 BGA devices.

Packaging:

• 192 pin BGA, 21mm x 21mm

3.3V Operating supply voltage

ꢀ

Direct control interface to both the CRAM and

VCRAM ports on the LUCTAPC640

The WED9LAPC3C16V8BC facilitates the addition of an

external Synchronous SRAM, effectively doubling the

SRAM array by adding a chip select/de-select function

(SSCE#).

ꢀ

62% space savings vs. monolithic solution

Reduced system inductance and capacitance

The WED9LAPC3C16V8BC is 100% tested to the timing

requirements of the LUCTAPC640’s memory interface

timing for both Commercial and Industrial temperature

ranges.
