CY7C028, CY7C027 Datasheet (Cypress Semiconductor) - 32K / 64K x 16 Dual-Port Static RAM

CY7C028, CY7C027, 32K / 64K x 16 Dual-Port Static RAM

The CY7C027 and CY7C028 are low power CMOS 32 K, 64 K × 16 dual-port static RAMs.

Various arbitration schemes are included on the devices to handle situations when multiple processors access the same piece of data.

Two ports are provided, permitting independent, asynchronous access for reads and wri
