The NXP MK50DX256CMC7 is a Kinetis K50-series 32-bit MCU built around an ARM Cortex-M4 core clocked at 72 MHz. It carries 256 KB of Flash program memory, 64K x 8 of SRAM, and 2K x 8 of EEPROM — enough firmware space and data retention for a sensor-fusion or motor-control application without external storage. The mixed-signal complement is the standout: 36 channels of 16-bit ADC and one 12-bit DAC, which lets this part handle multi-axis analog front-ends and closed-loop control outputs on a single chip. On-chip peripherals include DMA, I²S, LVD, POR, PWM, and WDT, plus connectivity for EBI/EMI, I²C, IrDA, SPI, UART/USART, USB, and USB OTG. The industrial temperature range (-40°C to 85°C) and 1.71 V to 3.6 V supply span make it a fit for factory-floor controllers, outdoor telecom nodes, and instrumentation panels that see thermal cycling.
