Product Overview EA2M: Serial CMOS EEPROM Memory, Low-Power 2Mb SPI For complete documentation, see the data sheet Product Description 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. OnChip 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.
