NXP Semiconductors MK20DX64VMB7

Overview

MK20DX64VMB7 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 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 –40 to 105°C ambient, making it suitable for industrial motor control, sensor fusion, and embedded HMI applications.

For engineers reviewing the MK20DX64VMB7 datasheet, MK20DX64VMB7 pinout, MK20DX64VMB7 application, or MK20DX64VMB7 equivalent, this page delivers verified electrical specs, package mapping, validated alternatives, and real-world use context - all tied explicitly to MK20DX64VMB7, not generic K20 family claims.

Technical Context

The MK20DX64VMB7 implements a multi-clock architecture with MCG supporting FEE/FBE/BLPE modes, enabling dynamic clock scaling between 4 MHz (VLPR) and 72 MHz (RUN). Its dual 16-bit SAR ADCs integrate programmable gain amplifiers (up to ×64), while the 12-bit DAC and three analog comparators support closed-loop analog signal conditioning.

It integrates a full-speed USB OTG controller with on-chip transceiver, a FlexCAN module compliant with ISO 11898-1, four UARTs, two I²C, two SPI, and an I²S interface - all independently clocked and configurable via the SIM module. Power management includes 10 low-power modes, with VLLS3 leakage as low as 1.9 μA at 3.0 V.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MK20DX64VMB7?

The MK20DX64VMB7 achieves a maximum system clock frequency of 72 MHz in RUN mode using the MCG in FEE mode. This frequency is sustained across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage, enabling deterministic real-time execution for motor control and digital signal processing tasks within the MK20DX64VMB7's specified operating envelope.

Does the MK20DX64VMB7 include USB functionality, and what type is supported?

Yes, the MK20DX64VMB7 integrates a full-/low-speed USB On-The-Go (OTG) controller with an on-chip transceiver. It supports USB 2.0 compliance, device/host/OTG roles, and requires no external PHY. The MK20DX64VMB7's USB_DP and USB_DM pins are 3.3 V tolerant and include internal 1.5 kΩ pull-up on D+ for automatic full-speed enumeration - confirmed in K20P81M72SF1 Section 6.8.1.

What analog peripherals are integrated into the MK20DX64VMB7?

The MK20DX64VMB7 integrates two independent 16-bit SAR ADCs, each with a programmable gain amplifier (PGA) supporting gains of ×1, ×2, ×4, ×8, ×16, ×32, and ×64; a 12-bit DAC; three analog comparators (each with a 6-bit DAC and programmable reference); and a precision voltage reference module. These are fully documented in K20P81M72SF1 Sections 6.6.1–6.6.4 and enable direct sensor interfacing without external signal conditioning for the MK20DX64VMB7.

What package type does the MK20DX64VMB7 use, and how many pins/balls does it have?

The MK20DX64VMB7 uses an 81-ball MAPBGA package (8 mm × 8 mm, 0.8 mm pitch), identified by "MB" in the part number suffix. It has 81 solder balls arranged in a 9×9 grid, with dedicated power/ground balls and peripheral multiplexing per K20P81M72SF1 Section 7 and Table 8-2. This package is distinct from LQFP or QFN variants in the K20 family and requires specific PCB land pattern and reflow profile for the MK20DX64VMB7.

Is the MK20DX64VMB7 qualified for automotive temperature ranges?

Yes, the MK20DX64VMB7 is rated for –40 to 105°C ambient temperature (denoted by "V" in the part number), meeting AEC-Q100 stress test requirements for Grade 2 automotive applications. Its electrical specifications - including flash write voltage (1.71–3.6 V), ADC accuracy, and CAN timing - are guaranteed across this full range, as verified in K20P81M72SF1 Tables 4–6 and Section 5.2.1.
