Description

NV25080LV, NV25160LV, NV25320LV, NV25640LV are

a EEPROM Serial 8/16/32/64−Kb SPI Low Voltage Automotive

Grade 1 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.
