It runs on a single 4.5 V supply and is rated across -55 to 125°C. The 120 ns access time and 170 ns write cycle define the bus timing margins. The 24501BVA is marked as end-of-life (EOL). No official successor is listed. If you are planning a new design, consider a drop-in 16Kbit alternative like 8403606JA (2K x 8, 70 ns, same 4.5 V supply and military temp range) — but verify the pinout and organization match your memory map before committing. ## Package and mounting — 18CERDIP through-hole The 18CERDIP ceramic dual-in-line package is through-hole mounted. It suits high-reliability assemblies where hermetic sealing is specified — military, aerospace, and long-life mission equipment. Bulk packaging means the part ships in tubes or trays, not tape-and-reel; plan for manual or low-volume pick-and-place.","metaTitle":"STMicroelectronics 24501BVA SRAM, 4Kbit Parallel, 120 ns","metaDescription":"STMicroelectronics 24501BVA SRAM, 4Kbit (4K x 1), parallel interface, 120 ns access, 4.5 V supply, -55 to 125°C, 18CERDIP.
