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

  • 1 MB 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 a 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

  • IEEE 1588 Ethernet MAC with hardware time stamping provides precision clock synchronization for real-time industrial control
  • 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 by 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
  • System security and tamper detect with a secure real-time clock with independent battery supply. Secure key storage with internal/external tamper detect for unsecured flash, temperature, clock, and supply voltage variations and physical attack detection
