This part is built for non-volatile firmware or calibration storage in avionics, missile guidance, satellite telemetry, and downhole instrumentation — any environment where a wide temperature swing and a parallel bus interface are non-negotiable. ## Military temperature range — deployment context Rated -55°C to 125°C. ## Lifecycle reality — EOL hot, sourced to order Lifecycle status is EOL hot — discontinued, no last-time-buy window. Available through independent distribution on a quoted-to-order basis. Write cycle time is 10 ms for a word or page write. That is typical for parallel EEPROM of this era — expect firmware updates to take on the order of seconds for a full 64 KB array. Plan your write routine accordingly; a 10 ms polling loop per byte is the safe approach.","metaTitle":"Renesas X28C513EMB-25 512Kbit Parallel EEPROM, 150 ns","metaDescription":"Renesas X28C513EMB-25 512Kbit parallel EEPROM, 150 ns access, 64K x 8, 32-CLCC, -55 to 125 °C.
