Features, Applications


High-density 4 megabyte Static RAM module Low profile 72-pin ZIP (Zig-zag In-line vertical Package) or 72-pin SIMM and Angled SIMM (Single In-line Memory Module) Fast access time: 15ns (max.) Surface mounted plastic components on an epoxy laminate (FR-4) substrate Single 5V (10%) power supply Multiple VSS pins and decoupling capacitors for maximum noise immunity Inputs/outputs directly TTL compatible

The PDM4M4120 is packaged 72-pin FR-4 ZIP (Zig-zag In-line vertical Package) a 72-pin SIMM or Angled SIMM (Single In-line Memory Module). The ZIP configuration allows 72 pins to be placed on a package 3.950" long and 0.365" wide. At only 0.590" 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 PDM4M4120 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. Four identification pins PD2, PD3) are provided for applications in which different density versions of the module are used. In this way, the target system can read the respective levels PD3 to determine a 1M depth.


The x 32 static RAM module constructed on an epoxy laminate (FR-4) substrate using eight x 4 static RAMs in plastic SOJ packages. Availability of four chip select lines (one for each of two RAMs) provides byte access. The PDM4M4120 is available with access times as fast as 15ns with minimal power consumption.
