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.
