M95080

16Kbit and 8Kbit Serial SPI Bus EEPROM With High Speed Clock

STMicroelectronics 

M95160, M95080

SUMMARY DESCRIPTION

These electrically erasable programmable memo-

ry (EEPROM) devices 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 tak-

en Low. Communications with the device can be

interrupted using Hold (HOLD).
