Functional description

The AS7C1026A and AS7C31026A are high-performance CMOS 1,048,576-bit Static Random Access Memory (SRAM) devices organized as 65,536 words × 16 bits. They are 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 3/3/4/5 ns are ideal for high-performance applications.
