Description  
PIN CONFIGURATION  
NV25128, NV25256 are EEPROM Serial 128/256 kb SPI  
Automotive Grade 0 devices internally organized as 16K/32Kx8 bits.  
It 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  
NV25xxx 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.
