Product details

Kinetis K50 MK51DX128CLH7 — ARM Cortex-M4 with USB and mixed-signal integration

The NXP MK51DX128CLH7 is a 32-bit ARM Cortex-M4 microcontroller from the Kinetis K50 series, running at 72 MHz with 128 KB of Flash program memory and 32 KB of RAM. The part also carries 2 KB of EEPROM for non-volatile parameter storage and an internal oscillator, reducing external component count on the board.

Mixed-signal headroom: 18-channel 16-bit ADC and 12-bit DAC

For a sensor-fusion board reading multiple thermocouples, strain gauges, or current shunts, this ADC channel count reduces the need for an external multiplexer or a second MCU. The DAC can generate a reference or an analog setpoint for a downstream regulator or amplifier stage.

Frequently asked questions

Does MK51DX128CLH7 have USB and what are its communication interfaces?

Yes, the MK51DX128CLH7 integrates a USB 2.0 OTG controller. Other serial interfaces include I²C, SPI, UART/USART, and IrDA. It also has a DMA controller to move data between peripherals without CPU intervention.

What is MK51DX128CLH7's listed speed?

The MK51DX128CLH7 runs at 72 MHz from its ARM Cortex-M4 core. At this speed the flash controller needs one wait state inserted for zero-wait access; the PLL and clock tree are configured through the internal oscillator.
