DESCRIPTION

The IDT7M1002 is a 16K x 32 high-speed CMOS Dual-Port Static RAM Module constructed on a co-fired ceramic substrate using four 16K x 8 (IDT7006) Dual-Port Static RAMs in surface-mounted LCC packages. The IDT7M1002 module is designed to be used as stand-alone 512K Dual-Port RAM or as a combination Master/Slave Dual-Port RAM for 64-bit or more word width systems. Using the IDT Master/Slave approach in such system applications results in full-speed, error free operation without the need for additional discrete logic.

FEATURES

? High-density 512K CMOS Dual-Port RAM module

? Fast access times

—Commercial: 30, 35ns

—Military: 40, 45ns

? Fully asynchronous read/write operation from either port

? Easy to expand data bus width to 64 bits or more using the Master/Slave function

? Separate byte read/write signals for byte control

? On-chip port arbitration logic

? INT flag for port-to-port communication

? Full on-chip hardware support of semaphore signaling between ports

? Surface mounted fine pitch (25 mil) LCC packages allow through-hole module to fit into 121 pin PGA footprint

? Single 5V (±10) power supply

? Inputs/outputs directly TTL-compatible
