Description

NV25128, NV25256 are EEPROM Serial 128/256 kb SPI

Automotive Grade 0 devices internally organized as 16K/32Kx8 bits.

It 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

NV25xxx device. The device features software and hardware write

protection, including partial as well as full array protection. Byte

Level On−Chip ECC (Error Correction Code) makes the device

suitable for high reliability applications. The device offers an

additional Identification Page which can be permanently write

protected.
