Description

The NV25640 is a EEPROM Serial 64−Kb SPI Automotive Grade 1

device internally organized as 8Kx8 bits. This 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 NV25640 device. The device

features software and hardware write protection, including partial as

well as full array protection.
