Description
M95160, M95080
The M95160, M95160-W, M95160-R, M95080, M95080-W and M95080-R are electrically
erasable programmable memory (EEPROM) devices. They are accessed by a high-speed
SPI-compatible bus. The memory array is organized as 2048 x 8 bit (M95160), and 1024 x 8
bit (M95080).
The device is accessed by a simple serial interface that is SPI-compatible. The bus signals
are C, D and Q, as shown in Table 2 and Figure 2.
The device is selected when Chip Select (S) is taken low. Communications with the device
can be interrupted using Hold (HOLD).
