Description

The NV25128 is a EEPROM Serial 128−Kb SPI Automotive

Grade 1 device internally organized as 16Kx8 bits. This features

a64−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 NV25128 device.

The device features software and hardware write protection, including
