It combines the non-volatility of EEPROM with the write speed and endurance of SRAM — no write delays, no page buffers, no wear-leveling needed. The 550 ns access time means the bus can run back-to-back reads and writes at the full 1 MHz clock without wait states, which is the main reason designers pick FRAM over serial EEPROM for data-logging or parameter-update-heavy applications. ## Obsolete — sourcing and replacement No official successor order code is provided in the lifecycle record. For new designs or BOM lines that need a drop-in, a pin-compatible FRAM in the same family with the same I²C interface, 64 Kbit density, and 8-SOIC footprint is the natural cross-shop candidate — verify supply voltage and temperature grade against the replacement. For existing production, surplus and broker channels are the route; we source and quote this part to order against an RFQ.","metaTitle":"FM24CL64B-GATR F-RAM 64Kbit I²C, 550 ns Access, Obsolete","metaDescription":"Cypress FM24CL64B-GATR 64Kbit FRAM, I²C 1 MHz, 2.7-3.6V, -40 to 125°C, 8-SOIC.
