Multistandard radio module (MSR module) block diagram MSR module block diagram 1
RF chip block diagram Mode of operation The radio part is software defined so it can operate in different modes, in the module this is as a Bluetooth or 802.15.4 transceiver. Al time critical tasks for the radio is handled by the ARM M0 CPU which is dedicate d for the radio. The communication with the main CPU is handler over a shared RAM. The main micro is an ARM M4F with op to 704K flash and 144K SRAM and 256K ROM (mostly used for operating system, BLE and 802.15.4 stack.
