The module utilises fast SRAMs housed in SOJ packages, and uses double sided surface mount techniques to achieve a very high density module. The module has four Chip Selects, which allow reading and writing to individual bytes or words. The pins PD0-3, are used to identify module memory density in applications where alternative modules can be interchanged. Features • Access Times of 12/15/20/25 ns. • 72 Pin ZIP, SIMM package • 5 Volt Supply ± 10%. • Low Power Dissipation: Average (min cycle) 7.48 W (Max). Standby -L Version (CMOS) 22 mW (Max). • Completely Static Operation. • On-board Supply Decoupling Capacitors. • Equivalent to EDI part EDI8F321024C, IDT part IDT7MP4120, and Cypress part CYM1851.

AC Read Characteristics Notes (1) WE is High for Read Cycle. (2) All read cycle timing is referenced from the last valid address to the first transition address. (3) tCHZ and tOHZ are defined as the time at which the outputs achieve open circuit conditions and are not referenced to output voltage levels. (4) At any given temperature and voltage condition, tCHZ (max) is less than tCLZ (min) both for a given module and from module to module. (5) These parameters are sampled and not 100% tested.
