Functional description

The AS7C513 is a high performance CMOS 524,288-bit Static Random Access Memory (SRAM) organized as 32,768 words × 16 bits. It is designed for memory applications where fast data access, low power, and simple interfacing are desired.

Equal address access and cycle times (tAA, tRC, tWC) of 10/12/15/20 ns with output enable access times (tOE) of 5/6/8/10 ns are ideal for high performance applications. The chip enable input CE permits easy memory expansion with multiple-bank memory systems.
