Functional description

The AS7C1025 and AS7C31025 are high-performance CMOS 1,048,576-bit Static Random Access Memory (SRAM) devices organized as 131,072 words × 8 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 12/15/20 ns with output enable access times (tOE) of 6,7,8 ns are ideal for high-performance applications. The chip enable input CE permits easy memory and expansion with multiple-bank memory systems.
