General Description
2
The SA25C020 is a 2Mb (512K X 4) CMOS
non-volatile serial EEPROM. This device
fully conforms to the SPI 4-wire protocol, is
enabled through the Chip Select (CSb) pin,
and uses Clock (SCK), Data-in (SI) and
Data-out (SO) pins to synchronously control
data

between
microcontroller and the Serial EEPROM.

The memory can be written from 1 up to
256 bytes at a time via the Byte / Page
Write (PW) instruction.
The memory consists of 1024 pages or
262,144 bytes.
Each device requires only a 3.0V power
supply (2.7 V to 3.6 V) for both read and
write functions. Internally generated and
regulated voltages are provided for the
