The M67025E is a very low power CMOS dual port static RAM organized as 8192 bit x 16. The product is designed to be used as a stand-alone 16-bit dual port RAM or as a combination MASTER/SLAVE dual port for 32-bit or more width systems. The Atmel MASTER/SLAVE dual port approach in memory system applications results in full speed, error free operation without the need of an additional discrete logic. Master and slave devices provide two independent ports with separate control, address and I/O pins that permit independent, asynchronous access for reads and writes to any location in the memory. An automatic power down feature controlled by CS permits the on-chip circuitry of each port in order to enter a very low stand by power mode.
