FRAM (Ferroelectric RAM) combines the speed of SRAM with the persistence of EEPROM — data is written instantly and retained for up to 95 years at room temperature.\n\nUnlike Flash or EEPROM, FRAM has no page-write limitations and supports an extraordinary 10 trillion read/write cycles per byte, virtually eliminating wear-levelling concerns. This makes it ideal for high-frequency datalogging and data buffering applications, especially in low-power or inconsistent-power environments.\n\nKey Features\n\n\n256 Kbit (32 KByte) FRAM Storage – Non-volatile memory with instant read/write access\n\nI2C Interface – Runs at up to 1 MHz clock rate for fast data transfer\n\n3V & 5V Compatible – Works with both 3.3V and 5V power and logic levels\n\n10 Trillion Write Cycles – Virtually unlimited endurance with no wear-levelling needed\n\n95-Year Data Retention – Non-volatile storage retains data without power\n\nNo Page Writes – Each byte is individually addressable, unlike Flash or EEPROM\n\nBreadboard-Friendly – Standard breakout board format with 0.1\" header pitch\n\n\nIdeal For\n\nHigh-frequency datalogging and sensor data buffering\nLow-power or battery-backed data storage\nConfiguration and calibration data that must survive power cycles\nProjects requiring fast, reliable non-volatile memory without EEPROM limitations\n\n\nPackage Contents\n\n1× Adafruit I2C FRAM Breakout Board (256 Kbit / 32 KByte)\n1× 0.1\" Male Header Strip\n\n\nResources\n\nAdafruit I2C FRAM Breakout Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13090,"title":"Default Title","sku":"AF-1895","price":19.96,"on_sale":false,"in_stock":true,"available_quantity":76,"option1":"Default Title"}]}
