It packs 128 KB of Flash program memory, 32 KB of SRAM, and 2 KB of EEPROM on-chip. 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. Standard serial interfaces — I²C, SPI, UART/USART, and IrDA — cover most sensor and actuator links. The 35 general-purpose I/O lines in the 64-LQFP package leave enough headroom for a keypad, display, and a few discrete controls without needing a port expander. ## Package and rework considerations The 64-LQFP package (10x10 mm body) is a garden-variety QFP. Tape & Reel and Cut Tape options are available. ## Sourcing and lifecycle The MK50DX128CLH7R carries an Active lifecycle status — no end-of-life notice, no last-time-buy window to track. That means it is still in regular production and can be specified into new designs without worrying about a forced redesign cycle. It is ROHS3 compliant, so no conflict with EU or global RoHS requirements.","metaTitle":"NXP MK50DX128CLH7R Kinetis K50 MCU, ARM Cortex-M4, 72 MHz","metaDescription":"NXP MK50DX128CLH7R 32-bit MCU with 128 KB Flash, 32 KB SRAM, 2 KB EEPROM, USB OTG, 22x16b ADC.
