- 16 GPIOs
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)
- 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
