DESCRIPTION

The ST950x0 is a family of Electrically Erasable

Programmable Memories (EEPROM) fabricated

with STMicroelectronics’s High Endurance Single

Polysilicon CMOS technology. Each 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).
