256 Kbit non-volatile FRAM with 40 MHz SPI
The Cypress FM25V02A-GTR is a 256 Kbit Ferroelectric RAM (FRAM) memory chip from the F-RAM™ series. It stores data as 32K x 8 bits and communicates over a standard SPI bus at up to 40 MHz. The supply range spans 2V to 3.6V, making it comfortable on a 3.3V rail or a 2.5V battery-backed line.
No last-time-buy notice, no phase-out date on the horizon.
2V to 3.6V supply — fits 3.3V and 2.5V rails
The supply range is 2V to 3.6V, so it works on a 3.3V rail with margin or on a 2.5V rail without a regulator. No level-shifting needed on the SPI lines if the host MCU runs at the same voltage. The 40 MHz clock is rated across the full supply range, so throughput doesn't drop at lower voltages.
8-SOIC — field-swappable footprint
Pin spacing is wide enough for hand soldering with a fine-tip iron, and the orientation is marked clearly on the package. If you are swapping this in a repair or retrofit, no hot-air station required — just a steady hand and a solder wick.
