EEPROM | NV25256
概览
NV25256 is a EEPROM Serial 128-Kb SPI - Automotive Grade 0 (+150°C) device internally organized as 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. 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.
