This document describes the features and characteristics of Alliance Semiconductor's AS7C1024A and AS7C31024A CMOS SRAM products, including industrial and commercial temperature ranges, organization structure, high-speed access time, low power consumption, easy expansion, compatibility, and packaging types.
The AS7C1024A (5 V) and AS7C31024A (3.3 V) are high‑performance 128 K×8 CMOS static RAMs organized as 131,072 words × 8 bits. They offer fast address access times (10‑20 ns) and low power consumption, with active‑mode power of 853 mW (AS7C1024A) or 522 mW (AS7C31024A) and standby power as low as 36 mW.
The document provides detailed specifications, including recommended operating conditions, absolute maximum ratings, timing diagrams, package dimensions, and ordering codes for various commercial and industrial temperature ranges and package types (SOJ, TSOP).
