It integrates a full-speed USB 2.0 OTG controller alongside I²C, SPI, UART/USART, and IrDA serial interfaces, making it a fit for embedded systems that need a single-chip host for both control and connectivity. 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 The on-chip data converter block provides 18 analog inputs multiplexed into a 16-bit ADC and a single 12-bit DAC output. 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. ## Active lifecycle — no LTB risk for new designs The MK51DX128CLH7 carries an active product status with ROHS3 compliance. For a BOM line that needs a production-qualified Cortex-M4 with USB OTG and a 16-bit ADC, this part is a current-generation choice — not a legacy part being phased out.","metaTitle":"NXP MK51DX128CLH7 Kinetis K50 MCU, ARM Cortex-M4 72 MHz","metaDescription":"NXP MK51DX128CLH7 32-bit MCU with 128 KB Flash, 32 KB RAM, USB OTG, 18x16-bit ADC.
