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).
