Two GPIO group interrupt modules enable an interrupt based on a programmable
pattern of input states of a group of GPIO pins.
Four general-purpose timer/counters with capture and match capabilities.
One motor control PWM for three-phase motor control.
One Quadrature Encoder Interface (QEI).
Repetitive Interrupt timer (RI timer).
Windowed watchdog timer.
Ultra-low power Real-Time Clock (RTC) on separate power domain with 256 bytes
of battery powered backup registers.
Event recorder with three inputs to record event identification and event time; can
be battery powered.
Alarm timer; can be battery powered.
One 10-bit DAC with DMA support and a data conversion rate of 400 kSamples/s.
Two 10-bit ADCs with DMA support and a data conversion rate of 400 kSamples/s.
Hardware-based AES decryption programmable through an on-chip API.
Two 128-bit secure OTP memories for AES key storage and customer use.
Random Number Generator (RNG) accessible through AES API.
Unique ID for each device.
Single 3.3 V (2.2 V to 3.6 V) power supply with on-chip internal voltage regulator for
the core supply and the RTC power domain.
RTC power domain can be powered separately by a 3 V battery supply.
Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep
power-down.
Processor wake-up from Sleep mode via wake-up interrupts from various
peripherals.
Wake-up from Deep-sleep, Power-down, and Deep power-down modes via
external interrupts and interrupts generated by battery powered blocks in the RTC
power domain.
Brownout detect with four separate thresholds for interrupt and forced reset.
Power-On Reset (POR).
