This puts it in the mid-range performance tier for Cortex-M3 parts — enough headroom for a CAN gateway, a motor-control loop with sensor feedback, or a USB-enabled human-machine interface without needing external memory. The 67 GPIOs in a 100-LQFP package give you room for a parallel LCD bus, a bank of opto-coupled inputs, and still leave pins for the debug header.
Connectivity and peripherals for industrial control
This MCU carries a CAN 2.0B controller, full-speed USB (device/host/OTG), multiple UARTs with IrDA and LIN support, plus SPI, I²C, and SSI serial interfaces. For motion control there's a quadrature encoder interface (QEI) and PWM timers. The 16-channel 12-bit ADC samples at rates suitable for current sensing or thermocouple linearisation.
For production runs or repair stock, procurement goes through the independent surplus and broker channel — sealed reels with consistent date-codes are the preferred buy, not mixed-date repackaged lots.
