– 32 kHz oscillator for RTC with calibration
– Internal 8 MHz RC with x 16 PLL option
– All mappable on external interrupt vectors
– Several 5 V-tolerant
Interconnect matrix
12-channel DMA controller
Four ADCs 0.20 μs (up to 40 channels) with
selectable resolution of 12/10/8/6 bits, 0 to
3.6 V conversion range, separate analog
supply from 2.0 to 3.6 V
Two 12-bit DAC channels with analog supply
from 2.4 to 3.6 V
Seven ultra-fast rail-to-rail analog comparators
with analog supply from 2.0 to 3.6 V
Four operational amplifiers that can be used in
PGA mode, all terminals accessible with analog
supply from 2.4 to 3.6 V
