Detailed Description

Asynchronous dual‑port SRAM, 64 Kbit total capacity organized as 8K x 8. Two independent ports can access the same memory array for fast, conflict‑free data sharing. 15 ns access and write cycle time for low‑latency reads and writes. Operates from a single 5 V supply 4.5 V to 5.5 V. Industrial temperature range −40°C to +85°C. Surface‑mount 64‑pin TQFP LQFP package 14 mm x 14 mm. RoHS3 compliant. Supplied on Tape and Reel for automated assembly. Parallel interface for simple connection to MCUs, DSPs, FPGAs, or bus logic
