DESCRIPTION
The ST95P08 is an 8 Kbit Electrically Erasable
Programmable Memory (EEPROM) fabricated with
STMicroelectronics’s High Endurance Single
Polysilicon CMOS technology. The 8 Kbit memory
is organised as 64 pages of 16 bytes. 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). The device connected to the bus is selected
when the chip select input (S) goes low. Commu-
nications with the chip can be interrupted with a
hold input (HOLD). The write operation is disabled
by a write protect input (W).
