SAE81C80A - CMOS Dual Port RAM

Datasheet Summary

Description

Dual-Port RAM The SAE 81C80A is a 504-byte static RAM simultaneously accessible by two microcontrollers.

The memory locations are selected via a multiplexed address/data bus and two chip-select inputs.

The direction of data transfer is determined by the RD and WR inputs.
