Industry-leading ARM® Cortex -M3 processor

- Leading 32-bit processing performance

- Highly efficient Thumb-2 instruction set

- Operation at 6, 12, or 24 MHz

- Flexible Nested Vectored Interrupt Controller

Low power consumption, advanced management

- RX Current (w/ CPU): 26 mA

- TX Current (w/ CPU, +3 dBm TX): 31 mA

- Low deep sleep current, with retained RAM and GPIO:

400 nA without/800 nA with sleep timer

- Low-frequency internal RC oscillator for low-power sleep

timing

- High-frequency internal RC oscillator for fast (110 µs)

processor start-up from sleep

Exceptional RF Performance

- Normal mode link budget up to 103 dB; configurable up

to 110 dB

- –100 dBm normal RX sensitivity; configurable to 

–102 dBm (1% PER, 20 byte packet)

- +3 dB normal mode output power; configurable up to

+8 dBm

- Robust Wi-Fi and Bluetooth coexistence

Innovative network and processor debug

- Packet Trace Port for non-intrusive packet trace with

Ember development tools

- Serial Wire/JTAG interface

- Standard ARM debug capabilities: Flash Patch & Break-

point; Data Watchpoint & Trace; Instrumentation Trace

Macrocell

Application Flexibility

- Single voltage operation: 2.1–3.6 V with internal 1.8 and

1.25 V regulators

- Optional 32.768 kHz crystal for higher timer accuracy

- Low external component count with single 24 MHz 

crystal

- Support for external power amplifier

- Small 7x7 mm 48-pin QFN package
