— Dedicated serial peripheral interface (SPI) connected internally to sub-1 GHz transceiver
— Multiple clock source options
– Internal clock generator (ICG) with 243 kHz oscillator that has +/-0.2% trimming resolution
and +/-0.5% deviation across voltage.
– Startup oscillator of approximately 8 MHz
– External crystal or resonator
– External source from modem clock for very high accuracy source or system low-cost option
— In-circuit debug and FLASH programming available via on-chip background debug module
(BDM)
— System protection features
– Programmable low voltage interrupt (LVI)
– Optional watchdog timer (COP)
– Illegal opcode detection
— Peripherals
– ADC — 10-channel, 12-bit resolution; 2.5 ms conversion time; automatic compare
function; 1.7 mV/°C temperature sensor; internal bandgap reference channel; operation in
stop3; fully functional from 3.6 V to 1.8 V
– ACMPx — Two analog comparators with selectable interrupt on rising, falling, or either
edge of comparator output; compare option to fixed internal bandgap reference voltage;
outputs can be optionally routed to TPM module; operation in stop3
