Program memory is 256 KB of Flash, backed by 64 KB of SRAM and a separate 2 KB EEPROM block for configuration parameters that survive reprogramming cycles. The 35-channel 16-bit ADC is the standout peripheral — enough resolution and channel count to sample multiple analog sensors without an external multiplexer, while the single 12-bit DAC handles analog output or waveform generation. Connectivity includes USB with OTG, multiple I²C and SPI buses, UARTs with IrDA support, and an I²S audio interface. The 78 GPIOs in the 121-MAPBGA package give enough headroom for a sensor array plus a display or keypad. The internal oscillator reduces external BOM count, though a crystal can be added for tighter timing accuracy. ## 121-MAPBGA footprint — layout notes for the 8x8 mm array The 121-MAPBGA (8x8 mm) package is a ball grid array. Decouple with a ceramic capacitor on the main rail and a capacitor per supply pin pair, placed as close to the balls as via geometry allows. The package is MSL 3 per the standard Kinetis BGA family — bake before reflow if the moisture barrier bag has been open longer than the floor-life window. No exposed thermal pad; junction temperature is managed through the BGA balls and the PCB copper plane. A four-layer board with a solid ground plane under the package is recommended for thermal and signal-integrity reasons. ROHS3 compliant — no exemption-driven lead content.","metaTitle":"NXP MK51DX256CMC7 Kinetis K50 MCU, ARM Cortex-M4, 72 MHz","metaDescription":"NXP MK51DX256CMC7 Kinetis K50 MCU: ARM Cortex-M4 at 72 MHz, 256 KB Flash, 64 KB RAM, 35x16-bit ADC, 121-MAPBGA.
