That makes it a drop-in replacement for serial EEPROM in applications that need fast, frequent writes: data loggers, event counters, configuration storage, or sensor calibration tables where the write endurance of EEPROM (typically 1M cycles) becomes a concern. ## SPI at 40 MHz — no dead cycles on writes The 40 MHz SPI clock means a full 256 Kbit read or write completes in roughly 800 µs at the bus level. The real win is the write path: FRAM writes happen in the same cycle as the SPI transaction — no polling for a write-complete bit, no waiting through a 5 ms EEPROM page write. For a firmware routine that logs a 32-byte sensor frame every 10 ms, the FM25V02A-DG never stalls the loop. The SPI interface supports mode 0 and mode 3, and the device is compatible with 3.3 V logic levels directly. ## Package and footprint — 8-DFN with exposed pad The FM25V02A-DG comes in an 8-WDFN with exposed pad (supplier package 8-DFN, 4x4.5 mm). The pad is electrically connected to the substrate (VSS), so the PCB land should be tied to the board ground plane with several vias.","metaTitle":"FM25V02A-DG Cypress F-RAM 256Kbit SPI 40MHz 8-DFN","metaDescription":"Cypress FM25V02A-DG 256Kbit FRAM, SPI 40 MHz, 2V-3.6V, -40°C to 85°C, 8-DFN.
