Description
The NV25010/20/40 are a EEPROM Serial 1/2/4−Kb SPI
Automotive Grade 1 devices internally organized as
128x8/256x8/512x8 bits. They feature a 16−byte page write buffer and
support the Serial Peripheral Interface (SPI) protocol. The device is
enabled through a Chip Select (CS) input. In addition, the required bus
signals are a clock input (SCK), data input (SI) and data output (SO)
lines. The HOLD input may be used to pause any serial
communication with the NV25010/20/40 device. These devices
feature software and hardware write protection, including partial as
well as full array protection.
