Description

NV25080, NV25160, NV25320, NV25640 are a EERPOM Serial

8/16/32/64−Kb SPI Automotive Grade 0 devices internally organized

as 1K/2K/4K/8Kx8 bits. It features a 32−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.
