NV25010, NV25020,
NV25040
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.
