Feature
Description
Mixed‐signal capability
• High‐speed 16‐bit ADC with configurable resolution
• Single or differential output modes for improved noise rejection
• 500 ns conversion time achievable with programmable delay block triggering
• Two high‐speed comparators providing fast and accurate motor overcurrent protection by
driving PWMs to a safe state
• Optional analog voltage reference provides an accurate reference to analog blocks
• One 12-bit DACs
Performance
• 120 MHz ARM Cortex‐M4 core with DSP instruction set, single precision floating point
unit, single cycle MAC, and single instruction multiple data (SIMD) extensions
• Up to four channel DMA for peripheral and memory servicing with reduced CPU loading
and faster system throughput
• Cross bar switch enables concurrent multimaster bus accesses, increasing bus bandwidth
• Independent flash banks allowing concurrent code execution and firmware updating with
no performance degradation or complex coding routines
Timing and control
• Four Flex Timers 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
• One low-power timer
• One independent real-time clock
Connectivity and
communications
• Full‐Speed USB device/host/on‐the‐go with device charge detect capability
• Optimized charging current/time for portable USB devices, enabling longer battery life
• USB low‐voltage regulator supplies up to 120 mA off-chip at 3.3 volts to power external
components from 5‐volt input
• Five UARTs:
— One UART supports RS232 with flow control, RS485, and ISO7816
— Four UARTs support RS232 with flow control and RS485
• One Inter‐IC Sound (I2S) serial interface for audio system interfacing
• Three DSPI modules and three I2C modules
• Secured digital host controller (SDHC)
• One FlexCAN module
• One Ethernet module with 1588
• A multifunction external bus interface (FlexBUS) controller capable of interfacing to slave-
only devices.
