Features
Ultra-Low-Power
- Flexible low-power modes with power and clock gating for optimal peripheral activity and recovery times. Stop currents of <340 nA, run currents of 250 µA/MHz, 4.5 µs wake-up from Stop mode
- Full memory and analog operation down to 1.71 volts for extended battery life
- Low-leakage wake-up unit with up to seven internal modules and 16 pins as wake-up sources in low-leakage stop (LLS)/very low-leakage stop (VLLS) modes
- Low-power timer for continuous system operation in reduced power state
Flash and SRAM
- Up to 1 MB of flash. Fast access, high reliability with four-level security protection
- 256 KB of SRAM
Mixed-Signal Capability
- Two high-speed, 16-bit analog-to-digital converters (ADCs) with configurable resolution. Single or differential output mode operation for improved noise rejection. 500 ns conversion time achievable with programmable delay block triggering
- Two 12-bit digital-to-analog converters (DACs) for analog waveform generation for audio applications
- Three high-speed comparators providing fast and accurate motor over-current protection by driving PWMs to a safe state
- Analog voltage reference provides an accurate reference to analog blocks, ADC and DAC, and replaces external voltage references to reduce system cost
Performance
- Arm® Cortex®-M4 core + DSP. 120 MHz, single-cycle MAC, single instruction multiple data (SIMD) extensions, single precision floating point unit
- Up to 16-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
- Crossbar switch enables concurrent multi-leader bus accesses, increasing bus bandwidth
- Independent flash banks allow concurrent code execution and firmware updating with no performance degradation or complex coding routines
Timing and Control
- Up to four FlexTimers with a total of 20 channels. Hardware dead-time insertion and quadrature decoding for motor control
- Carrier modulator timer for infrared waveform generation in remote control applications
- Four-channel 32-bit periodic interrupt timer provides time base for RTOS task scheduler or trigger source for ADC conversion and programmable delay block
Human-Machine Interface (HMI)
- GPIO with pin interrupt support
Connectivity and Communications
- USB 2.0 On-The-Go (full-speed) with USB transceiver. Intelligent design with embedded 48 MHz oscillator allowing for USB crystal-less system design. Device charge detect optimizes charging current/time for portable USB devices enabling longer battery life. Low-voltage regulator supplies up to 120 mA off-chip at 3.3 volts to power external components from 5 volts input
- Up to six UARTs with IrDA support including one UART with ISO7816 smart card support. Variety of data size, format and transmission/reception settings supported for multiple industrial communication protocols
- Inter-IC Sound (I²S) serial interface for audio system interfacing
- CAN module for industrial network bridging
- Three DSPI and three I²C
Reliability, Safety and Security
- Memory protection unit provides memory protection for all leaders on the crossbar switch, increasing software reliability
- Cyclic redundancy check engine validates memory contents and communication data, increasing system reliability
- Independent-clocked COP guards against clock skew or code runaway for fail-safe applications such as the IEC 60730 safety standard for household appliances
- External watchdog monitor drives output pin to safe state external components if watchdog event occurs
