描述 Description

NV25010LV, NV25020LV and NV25040LV are EEPROM Serial

1/2/4−Kb SPI Low Voltage Automotive Grade 1 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.
