The Adafruit I2C Non-Volatile 256Kbit / 32KByte FRAM breakout gives your next project fast, persistent storage using cool new ferroelectric RAM technology. It's low-power, has a fast write speed, and each location can be written to 10 trillion times. Once written, data will be kept safe for 95 years at room temperature, though there may not be Arduinos then. The I2C interface runs at 1MHz and the board is happy with 3 to 5V power and logic. Supplied as a fully assembled board plus a 1 x 8-pin 0.1in. pitch male header strip for you to solder in as required. * 256 Kbits (32 Kbytes) of storage * 2-wire I2C interface * 3 to 5V power and logic compatible * Adafruit part no. 1895 *Customers looking to resell on eBay or Amazon should contact Adafruit directly. https://elecena.pl/product/27279020/adafruit-1895-fram-breakout-i2c-non-volatile-256kbit-32kbyte 2024-11-14 https://elecena.pl/product/27279020/adafruit-1895-fram-breakout-i2c-non-volatile-256kbit-32kbyte 2025-03-28 https://elecena.pl/product/27279020/adafruit-1895-fram-breakout-i2c-non-volatile-256kbit-32kbyte 2025-05-12 https://elecena.pl/product/27279020/adafruit-1895-fram-breakout-i2c-non-volatile-256kbit-32kbyte 2025-06-17 https://elecena.pl/product/27279020/adafruit-1895-fram-breakout-i2c-non-volatile-256kbit-32kbyte 2025-07-26 https://elecena.pl/product/27279020/adafruit-1895-fram-breakout-i2c-non-volatile-256kbit-32kbyte 2025-09-25
