描述 Description

The M95512-W, M95512-R and M95512-DR are electrically erasable programmable memory (EEPROM) devices accessed by a high-speed SPI-compatible bus. In the rest of the document these devices are referred to as M95512, unless otherwise specified. The M95512-DR also offers an additional page, named the Identification Page (128 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 it can be used to store unique identification parameters and/or parameters specific to the production line.
