CAN controller with two channels.
Digital peripherals:
SD/MMC memory card interface.
Up to 165 General Purpose I/O (GPIO) pins depending on the packaging, with
configurable pull-up/down resistors, open-drain mode, and repeater mode. All
GPIOs are located on an AHB bus for fast access and support Cortex-M3
bit-banding. GPIOs can be accessed by the General Purpose DMA Controller. Any
pin of ports 0 and 2 can be used to generate an interrupt.
Two external interrupt inputs configurable as edge/level sensitive. All pins on port 0
and port 2 can be used as edge sensitive interrupt sources.
Four general purpose timers/counters, with a total of eight capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.
Quadrature encoder interface that can monitor one external quadrature encoder.
Two standard PWM/timer blocks with external count input option.
One motor control PWM with support for three-phase motor control.
Real-Time Clock (RTC) with a separate power domain. The RTC is clocked by a
dedicated RTC oscillator. The RTC block includes 20 bytes of battery-powered
backup registers, allowing system status to be stored when the rest of the chip is
powered off. Battery power can be supplied from a standard 3 V lithium button cell.
The RTC will continue working when the battery voltage drops to as low as 2.1 V.
An RTC interrupt can wake up the CPU from any reduced power mode.
Event Recorder that can capture the clock value when an event occurs on any of
three inputs. The event identification and the time it occurred are stored in
registers. The Event Recorder is located in the RTC power domain and can
therefore operate as long as there is RTC powe
