Processing power
The RN52m incorporates a powerful Cortex-M4F processor enabling the most demanding applications with
complex arithmetic requirements to be realized in a single chip solution. The IC supports DSP instructions, a
Floating Point Unit (FPU), single-cycle multiply and accumulate, and hardware divide for energy-efficient process
of computationally complex operations.
Multiprotocol radio
The 2.4GHz radio supports multiple protocols including Bluetooth low energy, ANT and 2.4GHz proprietary. The
radio has high definition RSSI and highly automated functionality, including EasyDMA for direct memory access
during packet send and retrieve. Nordic provides protocol stacks for Bluetooth low energy. ANT protocol stacks
are available from ANT here: www.thisisant.com.
Power Efficiency
The RN52m module is an extremely power efficient device that can run from a supply between 1.7V and 3.6V. All
individual peripherals and clocks offer complete flexibility of power down when not required for task operation
thus minimizing power consumption to a minimum. The IC has a comprehensive system of automated and
adaptive power management features. These features range across the entire IC’s operation from power supply
switching to peripheral bus/EasyDMA memory management, to automated shut down of all but the absolute
essential peripherals required to perform a task.
SoftDevice
The RN52m is supported by the S132 SoftDevice, a Bluetooth 5 pre-qualified protocol stack.
