Description

The M95256, M95256-W, M95256-R and M95256-DR are electrically erasable programmable memory (EEPROM) devices. They are accessed by a high speed SPI compatible bus. Their memory array is organized as 32768 × 8 bits. The M95256-DR also offers an additional page, named the Identification Page (64 bytes) which can be written and (later) permanently locked in Read-only mode. This Identification Page offers flexibility in the application board production line, as the Identification Page can be used to store unique identification parameters and/or parameters specific to the production line.
