Description

M95160-x, M95080-x

The M95160-x and M95080-x 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-x), and 1024 x 8 bit (M95080-x).

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 1.

The device is selected when Chip Select (S) is taken low. Communications with the device

can be interrupted using Hold (HOLD).
