Kinetis K20 MCU for mid-complexity embedded control
The NXP MK20DX64VLH5 is a 32-bit ARM Cortex-M4 microcontroller from the Kinetis K20 series, clocked at 50 MHz with 64 KB of Flash program memory, 16 KB of RAM, and 2 KB of EEPROM on-chip. The part is built for industrial environments with an operating temperature range of -40°C to 105°C and a supply voltage window from 1.71 V to 3.6 V, suiting it for motor drives, factory automation nodes, outdoor telecom gear, and battery-powered instrumentation.
50 MHz Cortex-M4 — throughput for control loops and data acquisition
The on-chip 16-bit ADC samples at sufficient rate for multi-channel analog front-ends in industrial transmitters or motor-current sensing.
Memory fit: 64 KB Flash, 16 KB RAM, 2 KB EEPROM
64 KB of Flash holds firmware for mid-complexity applications like Modbus slave stacks or basic HMI logic. The 16 KB RAM supports moderate data buffers and stack depth. The 2 KB EEPROM stores calibration constants and configuration parameters without needing external serial EEPROM — one less BOM line.
