The NXP MK20DX256VLK10R is a 32-bit ARM Cortex-M4 MCU clocked at 100 MHz, with 256 KB Flash, 64 KB RAM, and 4 KB EEPROM on-chip. It integrates USB OTG, CANbus, SPI, I²C, UART, SD, and an external bus interface. The 80-LQFP package with 52 I/O and a 1.71 V to 3.6 V supply range suits compact, mixed-voltage boards.
100 MHz Cortex-M4 — throughput and DSP capability
For a motor drive or power-converter controller, that clock speed buys headroom for sensorless FOC or PFC algorithms alongside communications stack overhead.
Memory and data converters
256 KB Flash and 64 KB RAM are sized for moderate firmware images and data buffers — enough for a CANopen stack with a few hundred parameters. The 4 KB EEPROM stores calibration constants and configuration without needing an external serial EEPROM, saving board area.
USB OTG lets the MCU act as either host or device, useful for on-the-fly data logging to a USB stick or connection to a PC for configuration. CANbus with the integrated controller and transceiver interface covers industrial fieldbus and automotive gateway roles. DMA, I²S, and PWM peripherals offload the core for time-critical tasks like audio streaming or multi-phase motor commutation.
Rated for -40°C to 105°C and 1.71 V to 3.6 V supply range.
