Can someone provide HOW MUCH RAM and Flash required for the Zibee Pro stack  ? and MCU computing power?

    Dears,

    You can refer to the map file that is generated by Zstack HA example for detail information.

    Thanks YiKai  for your reply

    But this sample example is for how much of nodes i.e. no of end-nodes,router ? etc..

    Hi Kiran

    My application is Wireless Sensor Network..? And for that i think it will not require this much of memory?

    which protocol u r using for WSN ? if Zstack pro then this much RAM FLASH needed.(under MSP430)

    Yes we are going to use zigbee pro with cc253x and MSP430f543x ..

    So you will be using the Z-Stack remotely by running the Z-Stack on the CC2530, which is referred to as a ZNP, ZigBee Network Processor, and the MSP is the host. You will only need to implement the uppermost layer on the host, the Application layer, so the memory requirements will be very much less than running directly on the Z-Stack (i.e. numbers above). So it depends on how sophisticated your Host code needs to be - two points of reference are the super small but super simplistic apps on the mini-ZNP kit and the full blown SE and HA compliant profiles implemented in the ZAP installer.

    Yes..we will use MSP430F with CC2530(z-stack PRO) for mesh topology(Combined circuit will act as end-device node /router) ..So as no of nodes increases ,does it effect on flash/ram size of  CC2530  (which is 256K & 10k)? Bcoz as no of nodes increases,tables and other information will need to handle in flash

    The CC2530 ZNP has enough memory for the default settings: neighbor table of 16, max associated devices of 20 (max of 6 of 20 as Routers). The bigger the network does not affect the maximums of any device in the network.
