CAT25512VI-GT3 Datasheet, PDF (1/16 Pages) ON Semiconductor – 512-Kb SPI Serial CMOS EEPROM

CAT25512
512-Kb SPI Serial CMOS
EEPROM
Description
The CAT25512 is a 512−Kb Serial CMOS EEPROM device
internally organized as 64Kx8 bits. This features a 128−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 CAT25512 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.
