Running a lightweight application code onto the Xbee ZB module.

Hi,

Is there any possibility where I can run a light weight application code onto the Xbee ZB module itself, elimination the need for an external microcontroller ??

Thanks,
Gaurav

Programmable XBee ZB…

Particularly:
Programmability
Memory 32 KB Flash / 2 KB RAM)
CPU/Clock Speed HCS08 / Up to 50.33 MHz

Have a read in the manual here:

The S2B modules that have the programmable option populated have a secondary processor with 32k of flash
and 2k of RAM. This allows module integrators to put custom code on the XBEE module to fit their own unique
needs.
