DESCRIPTION
The ST95022 is an high speed 2 Kbit Electrically Erasable Programmable Memory (EEPROM) fabricated 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).
