Product details

72 MHz ARM Cortex-M4 with integrated mixed-signal peripherals

The NXP MK50DX128CLH7R is a 32-bit microcontroller from the Kinetis K50 series, built around an ARM Cortex-M4 core clocked at 72 MHz. The 22-channel 16-bit ADC and single 12-bit DAC let it handle analog sensor inputs and generate analog outputs without external converters. Connectivity includes USB OTG for direct host/peripheral operation, plus EBI/EMI for external memory or parallel-bus expansion.

Package and rework considerations

The 64-LQFP package (10x10 mm body) is a garden-variety QFP. Tape & Reel and Cut Tape options are available.

It is ROHS3 compliant, so no conflict with EU or global RoHS requirements.

Frequently asked questions

Does MK50DX128CLH7R support USB OTG?

Yes, the connectivity list includes USB OTG, so the part can act as either a USB host or peripheral without an external OTG controller.

What is the closest pin-compatible alternative to MK50DX128CLH7R?

Within the Kinetis K50 family, other 64-LQFP devices with the same pinout but different Flash/RAM densities exist (e.g., MK50DX256CLH7 with 256 KB Flash). The exact pin-compatible variant depends on the required memory size; check the K50 family reference manual for the specific order code that matches your footprint and feature set.

What is MK50DX128CLH7R's listed speed?

The core runs at 72 MHz, which is the maximum clock for this Cortex-M4 implementation in the Kinetis K50 series.
