Product details
Overview
MK20DN32VLH5 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control applications requiring real-time signal processing and low-power operation. It features 32 KB program flash, 16 KB RAM, operates at up to 50 MHz, supports -40°C to +105°C ambient temperature, and integrates USB OTG, ADC, PWM timers, and multiple serial interfaces - deployed in industrial motor control systems.
For engineers reviewing the MK20DN32VLH5 datasheet, MK20DN32VLH5 pinout, MK20DN32VLH5 application, or MK20DN32VLH5 equivalent, key selection considerations include its 64-pin LQFP package, FlexMemory absence (flash-only configuration), VDD range of 1.71–3.6 V, integrated USB transceiver, and support for ultra-low-power stop modes down to 0.176 µA.
Technical Context
The MK20DN32VLH5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC operations, enabling efficient filtering and control loop execution. Its clock system includes a multi-purpose clock generator (MCG) supporting internal and external oscillators (3–32 MHz crystal, 32 kHz RTC crystal), plus configurable PLL paths for precise frequency synthesis.
Peripheral integration centers on deterministic real-time response: eight-channel TPM for motor control/PWM, two quadrature decoder timers, 16-bit SAR ADC with programmable sample time, dual analog comparators with 6-bit DACs, and three UARTs with FIFOs. Power management includes five low-power modes (VLPR, VLPS, LLS, VLLS0–VLLS3), each with distinct wake-up sources and current profiles validated across temperature.

FAQ
What is the maximum operating frequency of the MK20DN32VLH5?
The MK20DN32VLH5 supports a maximum system and core clock frequency of 50 MHz, as specified in the K20 Sub-Family Data Sheet Rev. 4. This frequency is achievable across the full -40°C to +105°C temperature range when supplied with 1.71–3.6 V. The MK20DN32VLH5 uses the MCG clock generator to derive this frequency from internal or external oscillators, and its performance is validated with Dhrystone benchmarking at 1.25 MIPS/MHz.
Does the MK20DN32VLH5 include FlexMemory?
No, the MK20DN32VLH5 does not include FlexMemory. The 'N' in its part number denotes "program flash only", confirming the absence of FlexNVM and FlexRAM. This distinguishes it from the MK20DX32VLH5 ('X' = flash + FlexMemory). The MK20DN32VLH5 provides 32 KB of program flash and 16 KB of RAM, with no emulated EEPROM capability - making it optimal for applications requiring fixed-function firmware without runtime data reprogramming.
What package type does the MK20DN32VLH5 use?
The MK20DN32VLH5 uses a 64-pin LQFP package (10 mm × 10 mm), identified by the 'LH' suffix in its part number per the K20 naming convention. This package is RoHS-compliant, has moisture sensitivity level 3, and is compatible with standard surface-mount assembly processes. Pin assignments follow the K20 signal multiplexing scheme documented in Section 8 of the K20 Sub-Family Data Sheet.
Can the MK20DN32VLH5 operate from a single 3.3 V supply?
Yes, the MK20DN32VLH5 operates reliably from a single 3.3 V supply. Its specified VDD range is 1.71 V to 3.6 V, fully encompassing 3.3 V ±10%. Both digital (VDD/VSS) and analog (VDDA/VSSA) domains are supported at this voltage, with ≤0.1 V differential tolerance between them. All peripherals - including USB transceiver, 16-bit ADC, and UARTs - are characterized and guaranteed at 3.3 V operation per the datasheet's electrical specifications.
What USB capabilities does the MK20DN32VLH5 support?
The MK20DN32VLH5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver, supporting USB 2.0 compliance at 12 Mbps (full-speed) and 1.5 Mbps (low-speed). It requires no external PHY, only 27 Ω series resistors on USB_DP/USB_DM and standard ESD protection. The MK20DN32VLH5 supports USB device, host, and OTG roles, with dedicated USB voltage regulator (VREGIN input) and internal pull-up/pull-down control for enumeration.
