White Electronic Designs Corp. reserves the right to change products or specications without notice.
The WED9LAPC2C16V8BC 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.
The WED9LAPC2C16V8BC 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.
The WED9LAPC2C16V8BC is 100% tested to the timing
requirements of the LUCTAPC640’s memory interface
timing for both Commercial and Industrial temperature
ranges.
512K x 32 SSRAM / 1M x 64 SDRAM
EXTERNAL MEMORY SOLUTION FOR LUCENT’S LUCTAPC640 ATM PORT CONTROLLER
Clock speeds:
SSRAM: 100 MHz
SDRAM: 100 MHz
100% tested to timing requirements of
LUCTAPC640’s memory interface
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
62% space savings vs. monolithic solution
Reduced system inductance and capacitance
