EEPROM Serial 1/2/4-Kb SPI

Automotive Grade 0

Description

NV25010, NV25020 and NV25040 are EEPROM Serial 1/2/4−Kb

SPI Automotive Grade 0 devices internally organized as 128x8, 256x8

and 512x8 bits. They feature a 16−byte page write buffer and support

the Serial Peripheral Interface (SPI) protocol. The devices are 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

NV250x0 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.
