Product details
Overview
MK20DN512VLL10 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control and signal processing in industrial and automotive applications. It operates at up to 100 MHz, integrates 512 KB flash and 128 KB RAM, supports -40°C to +105°C ambient temperature, and features dual CAN interfaces, USB OTG, and two 16-bit SAR ADCs with integrated PGA.
For engineers reviewing the MK20DN512VLL10 datasheet, MK20DN512VLL10 pinout, MK20DN512VLL10 application, or MK20DN512VLL10 equivalent, key selection considerations include its 100-pin LQFP package, 100 MHz core frequency, FlexBus interface, low-power stop modes down to 2.1 µA, and dual CAN 2.0B compliance - all critical for real-time motor control, sensor fusion, and connected industrial edge nodes.
Technical Context
The MK20DN512VLL10 implements an ARM Cortex-M4 core with hardware DSP instructions and a Memory Protection Unit (MPU), enabling deterministic real-time execution and secure multi-tasking. Its clock system includes a 3–32 MHz main crystal oscillator, 32 kHz RTC oscillator, and Multi-Purpose Clock Generator supporting dynamic frequency scaling across power modes.
Peripheral integration centers on mixed-signal capability: two independent 16-bit SAR ADCs each with programmable gain amplifier (up to ×64), 12-bit DAC, three analog comparators with internal 6-bit DACs, and TSI-based capacitive touch sensing. Communication is supported by five UARTs, three SPIs, two I²C modules, USB full/low-speed OTG, SDHC, and two CAN controllers compliant with ISO 11898-1.
