This is a volatile memory — data is lost when power drops — intended for high-reliability applications where a small, fast scratchpad or status register is needed: avionics memory-mapped I/O, satellite telemetry buffers, or missile-guidance sequencer storage. The 4K x 1 organization means each address returns a single bit, so this part is typically used in parallel banks for wider data words or as a single-bit-wide holding register, not for code execution or multi-byte data arrays. ## 35 ns access time — bus timing constraint Access time is 35 ns; write cycle time is 35 ns.","metaTitle":"5962-8858702XA 4Kbit Parallel SRAM, 35 ns, Ceramic Flatpack","metaDescription":"5962-8858702XA — 4Kbit (4K x 1) parallel SRAM, 35 ns access time, 4.5 V supply, 18-pin ceramic flatpack, -55°C to 125°C.
