Family of Microcontrollers
Analog Interfaces
4- to 16-channel 10-bit successive-
approximation A/D converter (ADC)
2-channel, 14-bit delta-sigma ADC
2- to 4-channel 8-bit D/A converter
Timers
Rich suite of 8-bit and 16-bit
multifunction, multipurpose timers
– Input capture, output compare, auto
reload, event counter, up/down counter,
interval timer, and sleep mode timer
3-phase Motor Control Timer
– 2-phase encoder with up/down count
capability
– Suitable for motor control apps
Asynchronous Event Counter (AEC)
– Counts events even when system clock
is disabled for power saving
Watchdog timer (WDT) with inde-
pendent RC circuit for greater safety
10-bit or 14-bit Pulse Width
Modulation (PWM) timer with
ripple-reduction feature
– Can be used as a D/A converter by
adding an external low-pass filter
Real-Time Clock (RTC): seconds,
minutes, hours, days and weeks
Arbitrary Waveform Generation /
Programmable Pulse Generator
(PPG) / Timing Pattern Controller
(TPC)
Arbitrary waveform patterns are
stored in memory and generated on
output pins with the PPG or TPC in
conjunction with a timer and DMA
Provides 8/16-bit programmable pulse
outputs using TPU as base
Output trigger signals can be selected
in 4-bit groups
Each group can operate both
simultaneously and independently
Output trigger signals can operate in
parallel with DTC and DMAC
