FRAM writes at bus speed without the write-cycle delay of serial EEPROM, and endurance is effectively unlimited for logging applications — no wear-leveling or sector management is needed at the firmware layer. ## Supply and interface fit The SPI bus supports Mode 0 and Mode 3, with the chip-select pin gating the serial clock. Housed in the standard 8-pin SOIC (150-mil body), footprint-compatible with common serial EEPROMs and FRAMs in the same package — a direct layout swap for a 4Kbit SPI memory at 3.3 V. Quantities are lot-specific and confirmed at RFQ.","metaTitle":"Infineon FM25L04B-GATR 4Kbit FRAM, SPI, AEC-Q100, 8-SOIC","metaDescription":"Infineon FM25L04B-GATR 4Kbit FRAM, SPI interface, 10 MHz, -40 to +125°C, AEC-Q100.
