Flash based non-volatile storage

Keywords:library  flash memory  non volatile storage 

This application note by describes the implementation and use of a library that allows on-chip flash memory to be used for non volatile storage, in a similar manner to EEPROM.

The NXP LPC1100, LPC1300, LPC1700 and LPC2000 family of ARM7 and ARM Cortex microcontrollers provide on-chip flash memory for storage of firmware. A frequent requirement for embedded systems is the storage of variables whose values need to persist through resets of the system. For microcontrollers without on chip EEPROM there are two basic options. One is to attach an external EEPROM device, perhaps using I2C or SPI. The second is to use the on-chip flash memory for variable storage.
