Description

The NV25256 is a EEPROM Serial 256−Kb SPI Automotive

Grade 1 device internally organized as 32Kx8 bits. This features a

64−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 NV25256 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.
