This document describes a CMOS 8192 x 8-bit Static Random Access Memory with features such as low standby supply current, fast address access time, and low data retention supply voltage. It is suitable for microprocessor-based systems and is easy to interface with Intersil 80C86 and 80C88 microprocessors.
The HM-65642/883 is an 8192 × 8‑bit CMOS static RAM designed for microprocessor‑based systems. It features low standby current, wide operating temperature range, and JEDEC‑standard 28‑pin packaging (CERDIP and CLCC). The document provides detailed pin descriptions, absolute maximum ratings, and both DC and AC electrical performance data.
Additional sections cover data‑retention operation, test circuit examples, die dimensions, and applicable test subgroups. The datasheet also includes handling cautions for electrostatic discharge and references to Intersil’s quality certifications.
