FRAM combines the non-volatile retention of flash with the instant read/write speed of SRAM — no page writes, no block erasing, and each byte can be written 10 trillion times without wear concerns.\n\nThis chip runs at up to 20 MHz SPI clock speeds, retains data for 95 years at room temperature, and is natively 5V compliant — no level shifting needed. It works with both 3V and 5V power and logic straight out of the box.\n\nKey Features\n\n\n64 Kbit FRAM Chip – 8 KBytes non-volatile ferroelectric RAM\n\nSPI Interface – Up to 20 MHz clock speed\n\nInstant Read/Write – No page writes or block erasing required\n\n10 Trillion Write Cycles – Virtually unlimited endurance per byte\n\n95-Year Data Retention – At room temperature\n\n5V Native – Works with both 3V and 5V power and logic\n\nBreadboard-Friendly – Includes 0.1\" header\n\n\nAlso Consider\n\n\nSPI FRAM Breakout – 2 Mbit / 256 KBytes – 32× more storage\n\nSPI FRAM Breakout – 4 Mbit / 512 KBytes – 64× more storage\n\n\nIdeal For\n\nHigh-speed data logging and buffering\nLow-power or inconsistent-power applications\nFrequent read/write scenarios where EEPROM wear is a concern\nNon-volatile storage that needs SRAM-like speed\n\n\nPackage Contents\n\n1× SPI FRAM breakout board (64 Kbit)\n1× Header strip\n\n\nResources\n\n\nAdafruit SPI FRAM Breakout Guide – Schematics, datasheets, and example code for Arduino and CircuitPython\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13095,"title":"Default Title","sku":"AF-1897","price":11.6,"on_sale":false,"in_stock":true,"available_quantity":101,"option1":"Default Title"}]}
