MK20DX64VLH5 - 50MHz Cortex-M4 64KB MCU | NXP
MPN： MK20DX64VLH5 ✓ 啟用中MK20DX64VLH5 概覽
A microcontroller is a semiconductor device that integrates a processor core, program memory, data memory, peripherals, and interface logic into one embedded-control component. In the hierarchy, the MK20DX64VLH5 is an MCU, a 32-bit microcontroller, and part of the Kinetis K20 family. Its Arm Cortex-M4 architecture provides a modern instruction set and deterministic control platform, while the 50 MHz operating frequency supports responsive main-loop or real-time-control execution. The verified sources specifically describe analog, communication, timing, and control peripherals, so the device is suitable for applications combining local computation with sensor acquisition and external control.
The principal verified features include a 50 MHz Arm Cortex-M4 processor, 64 KB flash, 16 KB SRAM, 64-LQFP packaging, USB connectivity, and low-power operation. The 64-LQFP package is 10 mm by 10 mm according to the DigiKey listing, providing a surface-mount solution with accessible perimeter leads for board assembly and inspection. The source snippets also identify a 3.3 V device variant in distributor listings. Exact operating voltage limits, GPIO count, ADC ratings, timer channels, USB electrical limits, memory endurance, and package thermal ratings were not supplied in the verified data and are therefore not inferred here.
Typical applications include USB-connected data acquisition, industrial sensing, motor and actuator control, communications equipment, test and measurement instruments, and compact consumer or embedded-control products. In these systems, the 50 MHz Cortex-M4 core can execute control software while the family’s analog, communication, timing, and control peripherals reduce the need for discrete support components. USB connectivity is particularly useful for configuration, logging, firmware update, or direct host-device communication when the board design includes the required routing and support circuitry.
The main design consideration is verification of the exact electrical, pin, peripheral, and package requirements before layout. Although the verified sources identify the 64-LQFP package, they do not provide a complete pin table in the supplied text. Do not infer USB, ground, power, reset, clock, or debug assignments from generic K20 family material without checking the official datasheet and reference manual. This page distinguishes confirmed distributor and manufacturer information from missing technical details rather than estimating them.

典型應用
MK20DX64VLH5 適用於 6 應用s: USB Data-Acquisition Controller, Industrial Sensor Interface, USB Configuration and Firmware Interface, Compact Motor and Actuator Control, Communication Equipment, Test and Measurement Instrument.
USB Data-Acquisition Controller
The MK20DX64VLH5 fits a USB data-acquisition controller when the design needs local computation, 64 KB flash, 16 KB SRAM, and full-speed USB in one device. The Cortex-M4 core can run sampling control, buffering, calibration, and host-interface software at up to the verified 50 MHz frequency. Use it between external sensors or converters and a USB host for configuration, logging, or real-time transfer. The tradeoff is that the supplied data does not specify ADC resolution, USB endpoint count, pin assignments, or electrical limits, so those details must be confirmed in the official datasheet before schematic capture.
推薦
Industrial Sensor Interface
For an industrial sensor interface, the MK20DX64VLH5 provides a 32-bit 50 MHz Cortex-M4 platform with analog, timing, and control peripherals identified in the verified family description. It can coordinate sensor conditioning, threshold logic, sampling timing, actuator commands, and communication from a compact controller. Its 64 KB flash and 16 KB SRAM are useful for moderate firmware and data buffers, but memory sizing must include protocol stacks and application code. Confirm the exact ADC, GPIO, voltage, temperature, and peripheral ratings before using it in a safety- or regulation-sensitive system.
推薦
USB Configuration and Firmware Interface
The MK20DX64VLH5 can act as the USB configuration and firmware interface for an embedded product when full-speed USB connectivity is needed alongside local control. A USB link can provide a commissioning path for parameter download, diagnostics, firmware updates, or data export, while the Cortex-M4 handles the device-side state machine. The verified data confirms USB functionality but does not provide endpoint, suspend, clock, or power-state details. Those values, along with the exact USB pins and required support components, must be validated against the official NXP documentation.
推薦
Compact Motor and Actuator Control
The MK20DX64VLH5 is suitable for compact motor or actuator control when the application needs deterministic embedded computation and a mix of timing, control, communication, and analog resources. Its 50 MHz Cortex-M4 core can run control algorithms, position or speed logic, fault monitoring, and communications, while the verified family description supports the peripheral mix. Package size and pin count help reduce board area, but motor systems also require verified voltage limits, logic levels, protection, timing resolution, and thermal margins. None of those application-specific ratings are supplied here, so they must be checked in the exact device documentation.
推薦
Communication Equipment
The MK20DX64VLH5 can support communication equipment requiring a 32-bit control plane, local protocol processing, and USB connectivity. The 50 MHz Cortex-M4 core provides headroom for framing, state management, diagnostics, and user-interface support, while the 64 KB flash and 16 KB SRAM fit compact firmware configurations. Communication quality depends on external transceivers, filtering, clocking, impedance control, and protocol timing that are outside this MCU’s verified specifications. Use the family’s communication peripherals as a starting point, then confirm the exact peripheral set and multiplexing for the selected LQFP variant.
推薦
Test and Measurement Instrument
For a compact test or measurement instrument, the MK20DX64VLH5 can coordinate acquisition, control, timing, and USB-based data transfer. The 50 MHz Cortex-M4 core handles instrument state, calibration, limits, and communications, while the verified K20 family description identifies analog and timing resources that can reduce external discrete overhead. The 64 KB flash and 16 KB SRAM are appropriate only for moderate application code and buffers; large datasets usually require external memory. Confirm ADC performance, timer accuracy, analog reference requirements, USB details, and calibration-related specifications before selecting the MCU for precision measurement.

主要差異化特點
- Verified 50 MHz Cortex-M4 performance class (對比MK10DX64VLH5)
- Full-speed USB connectivity is explicitly identified (對比MK10DX64VLH5)
- 64 KB flash and 16 KB SRAM in the verified K20 family description (對比MK10DN64VLH5)

設計說明
Use the verified 64-LQFP, 10 mm x 10 mm package designation to constrain the PCB footprint, but do not release the land pattern from the short distributor excerpt alone. Verify pad dimensions, pin numbering, pin-1 orientation, solder mask, and assembly clearances against the current NXP package drawing. A footprint error can make an otherwise electrically correct design unmanufacturable.
The verified listing identifies a 3.3 V device variant, but the supplied excerpts do not provide the complete operating-voltage range, decoupling requirements, current limits, or power-sequencing rules. Design the power tree from the official MK20DX64VLH5 datasheet, place required bypass capacitors at the specified pins, and verify startup and shutdown behavior across the complete load and temperature range before layout release.
Full-speed USB connectivity is confirmed by the verified family information, but USB pin assignments, impedance requirements, routing guidance, and support-circuit values are not. Confirm the exact USB implementation in the official datasheet, preserve the required return paths, minimize stub length, and follow the manufacturer’s routing and grounding guidance rather than relying on generic USB layout assumptions.
Do not treat same-package, same-frequency, or similar-memory candidates as automatic drop-in replacements. The cross-reference excerpts identify related NXP candidates but do not establish identical pin multiplexing, USB behavior, peripheral mapping, electrical limits, or firmware compatibility. Before replacing MK20DX64VLH5, compare the official datasheets and verify PCB pins, clocking, interrupts, memory organization, and software driver assumptions.
合規資訊
The supplied verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance claims must be confirmed from the current manufacturer product documentation or supplier documentation.
