CXK58257CM-70LL Static RAM For Service Replacements

CXK58257CM-70LL is a fit for embedded controllers, instrumentation, and older CPU boards that still rely on asynchronous static RAM. The device is a 262,144-bit CMOS SRAM organized as 32,768 words × 8 bits, so it maps cleanly into 8-bit data paths and classic address decoding. It operates from a single 5 V supply and is available in a 28-pin SOP package family, supporting compact board layouts. The -70LL speed grade is specified for 70 ns max access time, which helps timing closure on quicker parallel buses. Use CXK58257CM-70LL where predictable read/write cycles matter and refresh is not an option. Request a quote for CXK58257CM-70LL.
