NXP Semiconductors MK20DX64VMC7

Overview

MK20DX64VMC7 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 core microcontroller with DSP extensions, 64 KB flash, 16 KB SRAM, and integrated USB OTG, CAN, dual ADCs, DAC, and TSI. It operates from 1.71–3.6 V at up to 72 MHz and supports industrial temperature range (–40 to 105°C). Used in motor control, industrial sensing, and USB-connected embedded systems requiring real-time analog processing and low-power operation.

For engineers reviewing the MK20DX64VMC7 datasheet, MK20DX64VMC7 pinout, MK20DX64VMC7 application, or MK20DX64VMC7 equivalent, key selection criteria include its 72 MHz Cortex-M4 performance, dual 16-bit SAR ADCs with PGA, USB full/low-speed OTG with on-chip transceiver, CAN 2.0B interface, and support for multiple low-power modes down to 1.47 µA in VLLS1 mode.

Technical Context

The MK20DX64VMC7 implements a multi-clock architecture with MCG (Multipurpose Clock Generator), supporting crystal oscillators at 3–32 MHz and 32 kHz, plus internal reference clocks. Its system includes an 8-channel PWM timer, two quadrature decoder timers, RTC, and programmable delay block - all synchronized to the 72 MHz core clock.

Analog subsystem integration includes two independent 16-bit SAR ADCs each with integrated PGA (gain up to ×64), a 12-bit DAC, three analog comparators with 6-bit DACs, and voltage reference. Communication stack comprises USB OTG, FlexCAN, five UARTs, two SPIs, two I²Cs, I²S, and EZ-Port for flash programming.

FAQ

What is the maximum operating frequency of the MK20DX64VMC7?

The MK20DX64VMC7 supports a maximum system and core clock frequency of 72 MHz, achieved using the MCG in FEE mode with an external 3–32 MHz crystal. This frequency is validated across the full –40 to 105°C temperature range and 1.71–3.6 V supply, delivering 115 DMIPS performance for real-time control tasks while maintaining USB full-speed timing compliance.

Does the MK20DX64VMC7 include a hardware floating-point unit (FPU)?

No, the MK20DX64VMC7 uses the ARM Cortex-M4 core with DSP extensions but does not integrate a hardware FPU. Its part number suffix 'D' (in MK20DX) explicitly denotes the DSP-enabled variant without FPU - confirmed in K20 Sub-Family Data Sheet Section 2.3. Applications requiring intensive floating-point math must use software libraries or select an 'F' suffix variant like MK20FX512VLQ12.

What package type does the MK20DX64VMC7 use, and what are its key mechanical features?

The MK20DX64VMC7 uses a 121-pin MAPBGA package (MC suffix), measuring 8 mm × 8 mm with 0.5 mm ball pitch and RoHS-compliant finish. It features exposed thermal pad for enhanced heat dissipation and supports standard reflow profiles per IPC/JEDEC J-STD-020. Pin assignments follow K20P100M72SF1 Rev. 3, Section 8.2, including dedicated USB, CAN, ADC, and TSI signal groups.

Can the MK20DX64VMC7 operate in USB device mode without external components?

Yes, the MK20DX64VMC7 integrates a full-speed USB 2.0 transceiver and 3.3 V regulator, enabling standalone USB device operation. Only two 27 Ω series resistors on USB_DP/DM and a 1.5 kΩ pull-up resistor on USB_DP (for full-speed enumeration) are required - no external PHY, level shifter, or voltage regulator needed for basic CDC or HID functionality.

How does the MK20DX64VMC7 support low-power design in battery-operated applications?

The MK20DX64VMC7 provides seven low-power modes, including VLLS1 with 1.47 µA typical current at 3.0 V and –40 to 25°C. It retains RAM, RTC, and selected peripherals in deep sleep, wakes in <4.2 µs from STOP mode, and supports autonomous wake-up via GPIO, comparator, or RTC alarm - making it ideal for energy-constrained sensor nodes and portable diagnostics tools.
