*Stress greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions greater than those indicated in operational sections of this specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

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 LUCTAPC640 ATM 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.
