Description
The M95128, M95128-W and M95128-R are electrically erasable programmable memory
(EEPROM) devices accessed by a high speed SPI-compatible bus. The memory array is
organized as 16384 x 8 bits.
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).
In order to meet environmental requirements, ST offers these devices in ECOPACK®
