DESCRIPTION

The ST95022 is an high speed 2 Kbit Electrically

Erasable Programmable Memory (EEPROM) fab-

ricated with STMicroelectronics’s High Endurance

Single Polysilicon CMOS technology. The memory

is accessed by a simple SPI bus compatible serial

interface. The bus signals are a serial clock input

(C), a serial data input (D) and a serial data output

(Q).
