Arduino library which defines methods for accessing most of the Fujitsu MB85nnn family FRAM memories. The library allows efficient reading from and writing to Fujitsu FRAM memories using I2C and allowing use of objects such as arrays or structures in addition to writing single bytes at a time. The FRAM memory has several advantages over conventional SRAM in that it allows at least 10 trillion read/write cycles which means that the programmer doesn't have to worry about heavy use of FRAM for changing data. The FRAM is 5V tolerant and there is an Adafruit breakout available.
Up to 8 devices can be put on an I2C and the library allows several memories to be treated as one large contiguous memory. The following memories are supported:
| Memory Type | Storage Bits | Datasheets |
| MB85RC512T | 512 kbit / 64KB | MB85RC512T Datasheet |
| MB85RC256V | 256 kbit / 32KB | MB85RC256V Datasheet |
| MB85RC128A | 128 kbit / 16KB |
MB85RC64TA Datasheet MB85RC64A Datasheet MB85RC64V Datasheet |
See the Wiki pages for details of the class and the variables / functions accessible in it.
