Kinetis K20 at 100 MHz — what the core speed buys you
The 512 KB Flash and 128 KB RAM support firmware with USB, CANopen, and an RTOS.
Industrial temperature and analog integration
The 42-channel 16-bit ADC and dual 12-bit DAC let you sample multiple current-sense resistors and generate a reference or control voltage without external converters — a BOM consolidation move that also keeps the layout tight.
The 100 GPIOs in the 144-LQFP package give enough pins to drive a parallel LCD, a keypad matrix, and a handful of sensors without a port expander. DMA offloads the core for high-throughput data moves, and the I²S interface handles audio codecs directly.
NXP has marked this device as Not Recommended for New Designs (NRND). If you are qualifying a new board, look at the active Kinetis K2x or K6x family members for a pin-compatible path forward.
