The 170 MHz clock is the headline number, but the practical gain comes from the Cortex-M4F's DSP extensions and single-cycle MAC. If your firmware runs a PID loop or a floating-point filter, this core saves you the cycle-count gymnastics an M3 or M0+ would need. The 112 KB SRAM gives enough headroom for two 256-point FFT buffers plus the control stack.
Analog peripherals: 24-channel ADC, 4-channel DAC
Twenty-four 12-bit ADC channels and four 12-bit DAC channels are on-chip. For a mixed-signal design like a three-phase motor controller with current sensing on all legs plus a DAC output for an analog reference, you can keep the bill of materials tight — no external ADC or DAC needed. The ADC can sample multiple channels in sequence without CPU intervention via the DMA engine listed in the peripherals block.
64-UFBGA 5x5 mm — layout and rework notes
The 52 I/O count in this package gives enough GPIO for a CAN node with a parallel LCD or a sensor array, but every pin is committed; there's no room for a spare.
On the connectivity side: CANbus, I2C, SPI, UART/USART, and USB are all present, along with SAI for audio serial interfaces and IrDA/IRTIM for infrared. The Brown-out Detect/Reset, POR, and WDT are standard safety peripherals for industrial environments.
It fits factory automation, outdoor telecom cabinets, and HVAC controllers.
