EA2M Datasheet, PDF (1/14 Pages) ON Semiconductor – 2 Mb SPI Serial CMOS EEPROM

EA2M
2 Mb SPI Serial CMOS
EEPROM
Description
The EA2M is a 2 Mb Serial CMOS EEPROM device internally
organized as 256Kx8 bits. This features a 256−byte page write buffer
and supports the Serial Peripheral Interface (SPI) protocol. The device
is enabled through a Chip Select (CS) input. In addition, the required
bus signals are clock input (SCK), data input (SI) and data output (SO)
lines. The HOLD input may be used to pause any serial
communication with the EA2M device. The device features software
and hardware write protection, including partial as well as full array
protection. On−Chip ECC (Error Correction Code) makes the device
suitable for high reliability applications.
The EA2M device is designed for ultra−low power consumption,
targeting real−time data logging applications, hearing aids and
other medical devices and battery operated applications.
