The KM62256C family is a low-power CMOS static random access memory (SRAM) fabricated by SAMSUNG using 0.7-micrometer CMOS technology. The family supports a variety of operating temperature ranges and has a variety of package types for user flexibility in system design. The family also supports low data retention voltage for battery back-up operation with low data retention current.
The KM62256C family is a low‑power 32K×8‑bit CMOS static RAM fabricated by Samsung. It is offered in several package types (28‑DIP, 28‑SOP, 28‑TSOP) and supports commercial, extended and industrial temperature ranges.
The document provides detailed electrical specifications, timing diagrams, data‑retention characteristics and ordering information for the various speed bins (45 ns, 55 ns, 70 ns, 100 ns).
