NXP Semiconductors MK20DX64VLH7

Overview

MK20DX64VLH7 from NXP Semiconductors (formerly Freescale) is a Kinetis K20-series 32-bit ARM Cortex-M4 microcontroller with DSP extensions, 64 KB flash, 16 KB SRAM, and 64-pin LQFP package. It operates from 1.71–3.6 V at –40 to 105°C, integrates USB OTG, CAN, dual 16-bit ADCs with PGA, 12-bit DAC, and real-time clock - deployed in industrial motor control and embedded HMI systems.

For engineers reviewing the MK20DX64VLH7 datasheet, MK20DX64VLH7 pinout, MK20DX64VLH7 application, or MK20DX64VLH7 equivalent, key selection criteria include its 72 MHz max CPU frequency, FlexMemory support, low-power stop modes down to 1.47 µA, and integrated analog subsystem for sensor interface and closed-loop control.

Technical Context

The MK20DX64VLH7 implements the ARM Cortex-M4 core with DSP instructions and no FPU. Its MCG clock system supports multiple modes including FEE (72 MHz), FEI (internal 4 MHz), and BLPE (low-power 4 MHz), enabling dynamic power/performance scaling across run, wait, VLPR, STOP, and VLLS modes.

Peripherals are organized into functional domains: dual ADCs with programmable gain amplifiers (x1–x64), three analog comparators with internal 6-bit DACs, eight-channel PWM timer, two quadrature decoder timers, and USB full/low-speed OTG with on-chip transceiver - all accessible via multiplexed I/O pins under configurable port control registers.

FAQ

What is the maximum operating frequency of the MK20DX64VLH7?

The MK20DX64VLH7 supports a maximum system and core clock frequency of 72 MHz in normal run mode. This is achieved using the Multipurpose Clock Generator (MCG) in FEE mode with an external crystal or oscillator. The bus clock runs up to 50 MHz, and flash access is optimized for 25 MHz operation - ensuring deterministic execution of time-critical control algorithms in the MK20DX64VLH7.

Does the MK20DX64VLH7 include USB functionality?

Yes, the MK20DX64VLH7 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver. It supports USB 2.0 device mode at 12 Mbps (full-speed) and 1.5 Mbps (low-speed), eliminating the need for an external PHY. The MK20DX64VLH7 USB module includes dedicated endpoints, DMA support, and suspend/resume handling - enabling HID, CDC, and mass-storage class implementations directly in the MK20DX64VLH7.

What analog peripherals are integrated into the MK20DX64VLH7?

The MK20DX64VLH7 integrates two independent 16-bit SAR ADCs, each with a programmable gain amplifier (PGA) offering gains from x1 to x64; a 12-bit DAC; three analog comparators (each with a built-in 6-bit DAC and programmable reference); and a precision voltage reference. These resources enable high-fidelity sensor interfacing, closed-loop analog control, and mixed-signal signal conditioning - all within the MK20DX64VLH7 without external components.

What low-power modes does the MK20DX64VLH7 support?

The MK20DX64VLH7 supports seven low-power modes: RUN, WAIT, VLPR, STOP, VLPS, LLS, and VLLS (with sub-modes VLLS0–VLLS3). In VLLS1 mode, it draws just 1.47 µA at –40 to 25°C while retaining RAM content and enabling wake-up from GPIO or RTC. The MK20DX64VLH7's low-leakage wakeup unit and configurable clock gating allow granular power optimization across diverse use cases - a defining capability of the MK20DX64VLH7.

Is the MK20DX64VLH7 pin-compatible with other K20 family members?

The MK20DX64VLH7 is pin-compatible with other 64-pin LQFP K20 variants sharing the LH package identifier, including MK20DX128VLH7 and MK20DX256VLH7. All share identical pin assignments, electrical characteristics, and peripheral mapping - enabling hardware reuse across flash-size variants. However, pin compatibility does not extend to different packages (e.g., QFN or BGA) or sub-families (e.g., K22 or K64), and the MK20DX64VLH7 requires verification of flash configuration and clock tree initialization for seamless migration.
