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) Standby -L Version (CMOS) • • • Completely Static Operation. On-board Supply Decoupling Capacitors. Equivalent to EDI part EDI8F321024C, IDT part IDT7MP4120, and Cypress part CYM1851. 7.48 W (Max). 22 mW (Max).
