Product details
Overview
MK50DX128CLH7R from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extension, operating at 72 MHz, featuring 128 KB program flash, 32 KB SRAM, and 32 KB FlexNVM for configurable EEPROM/data storage. It integrates dual 16-bit ADCs, one 12-bit DAC, two analog comparators, USB OTG LS/FS with device charger detect, and supports industrial temperature range (–40°C to +85°C) in a 64-pin LQFP package.
For engineers reviewing the MK50DX128CLH7R datasheet, MK50DX128CLH7R pinout, MK50DX128CLH7R application, or MK50DX128CLH7R equivalent, key selection criteria include its FlexMemory configurability, USB DCD capability, 5V-tolerant GPIO, low-power timer support, and compatibility with Kinetis SDK and MCUXpresso IDE for rapid embedded development.
Technical Context
The MK50DX128CLH7R implements an ARM Cortex-M4 core with hardware-accelerated DSP instructions but no floating-point unit. Its memory subsystem includes independent FlexNVM (32 KB) partitionable between data flash and high-endurance EEPROM emulation via FlexRAM (2 KB), enabling byte-write/erase operations without CPU intervention.
Peripherals are organized around a multi-channel DMA controller (16 channels), dual FTM modules (1×8-channel motor control/PWM + 2×2-channel quadrature decoder), CMT for IR carrier generation, and full-speed USB OTG with integrated transceiver and dedicated charger detection logic - all clocked via MCG with FLL/PLL options and supported by low-leakage wake-up unit for ultra-low-power operation.

FAQ
What is the maximum operating frequency and core type of the MK50DX128CLH7R?
The MK50DX128CLH7R features an ARM Cortex-M4 core with DSP instruction set and operates at a maximum frequency of 72 MHz. It does not include a floating-point unit (FPU). This configuration balances computational throughput for signal processing tasks - such as motor control or sensor fusion - with deterministic real-time behavior and low power consumption, making it suitable for battery-operated and thermally constrained applications where the MK50DX128CLH7R is deployed.
Does the MK50DX128CLH7R support USB Device Charger Detect (DCD), and how is it implemented?
Yes, the MK50DX128CLH7R includes dedicated hardware for USB Device Charger Detect (DCD) compliant with USB Battery Charging Specification v1.2. It autonomously identifies SDP (standard downstream port), CDP (charging downstream port), and DCP (dedicated charging port) sources using internal current-sensing circuitry on the USB D+ line. This feature is fully integrated into the USB OTG controller and requires no external components, enabling the MK50DX128CLH7R to configure optimal charging current without host CPU intervention.
How is FlexMemory configured on the MK50DX128CLH7R, and what are its practical benefits?
The MK50DX128CLH7R includes 32 KB FlexNVM and 2 KB FlexRAM. FlexRAM can be allocated as high-endurance EEPROM (up to 10 million write/erase cycles) or as additional system RAM, while FlexNVM can serve as extra program flash, data flash, or EEPROM backup storage. Configuration is done at runtime via flash configuration registers. This eliminates external EEPROM ICs and avoids software-based emulation overhead - a key advantage in applications where the MK50DX128CLH7R manages calibration data, usage logs, or secure keys with frequent updates.
What analog peripherals are integrated into the MK50DX128CLH7R, and how do they support precision measurement?
The MK50DX128CLH7R integrates two 16-bit SAR ADCs (ADC0 with 15 SE + 1 DP channels; ADC1 with 12 SE + 2 DP channels), one 12-bit DAC, two analog comparators, one programmable gain amplifier (PGA), and an internal voltage reference. These peripherals support synchronized sampling, hardware-triggered conversions, and flexible input routing - enabling high-accuracy measurements in applications like energy metering or biomedical sensing where the MK50DX128CLH7R performs real-time signal conditioning and digitization without external signal chain components.
Is the MK50DX128CLH7R pin-compatible with other Kinetis K50 devices, and what package does it use?
Yes, the MK50DX128CLH7R uses a 64-pin LQFP (10 mm × 10 mm) package identified by the "LH" suffix, and all K50 devices sharing the LH package are pin-for-pin compatible per Freescale's documentation. This allows direct migration to higher-flash variants (e.g., MK50DX256CLH7R) or alternate sub-families (e.g., MK51DX128CLH7R) without PCB redesign. The MK50DX128CLH7R maintains identical pin mapping for power, reset, debug, USB, and primary peripheral signals across this package group.
