Features, Applications

The x 32 static RAM module constructed on an epoxy laminate (FR-4) substrate using four x 8 static RAMs in plastic SOJ packages. The PDM4M4040 is available with access times as fast 12 ns with minimal power consumption. The PDM4M4040 is packaged 64-pin FR-4 ZIP (Zig-zag In- line vertical Package) a 64-pin SIMM (Single In-line Memory Module). The ZIP configuration allows 64 pins to be placed on a package 3.65" long and 0.21" wide. At only 0.60" high, this low-profile package is ideal for systems with minimum board spacing. The SIMM configuration allows use of edge mounted sockets to secure the module. All inputs and outputs of the PDM4M4040 are TTL compatible and operate from a single 5V supply. Full asynchronous circuitry requires no clock or refresh for operation and provides equal access and cycle times for ease of use.
