Description
The M95640, M95640-W and M95640-R are electrically erasable programmable memory
(EEPROM) devices. They are accessed by a high-speed SPI-compatible bus. The devices
are 64 Kbit devices organized as 8192 × 8 bits.
The M95640-D also offers an additional page, named the Identification Page (32 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.
The device is accessed by a simple serial interface that is SPI-compatible. The bus signals
are C, D and Q, as shown in
The device is selected when Chip Select (S) is taken low. Communications with the device
can be interrupted using Hold (HOLD).
