ARM Cortex-M4 at 50 MHz — small-footprint MCU for industrial control
It has 32 KB Flash, 8 KB RAM, and 2 KB EEPROM on-chip.
Industrial temperature grade and wide supply — fits harsh environments
Rated for -40°C to 105°C, the MK20DX32VFT5 operates from 1.71 V to 3.6 V supply.
Peripherals and connectivity — USB OTG, I²S, 11-channel 16-bit ADC
On the peripheral side, the MK20DX32VFT5 includes USB OTG, I²C, SPI, UART/USART, and IrDA for connectivity, plus an 11-channel 16-bit ADC for sensor inputs. DMA, I²S, LVD, POR, PWM, and WDT round out the set — enough for a human-machine interface panel or a sensor hub that needs audio or waveform output.
That means NXP continues to manufacture it, and there is no last-time-buy or end-of-life notice to track. For a BOM freeze, this part is a stable line item — no urgency to source a replacement.
