General Purpose Flash Memory

XBee 868LP RF Modules provides 119 512-byte blocks of flash memory that an application can read and write to. This memory provides a non-volatile data storage area that an application uses for many purposes. Some common uses of this data storage include:

• Storing logged sensor data
• Buffering firmware update data for a host microcontroller
• Storing and retrieving data tables needed for calculations performed by a host microcontroller

The General Purpose Memory (GPM) is also used to store a firmware update file for over-the-air firmware updates of the device itself.
