The NXP MK20DX128VLH7 is a 32-bit ARM Cortex-M4 MCU from the Kinetis K20 series, clocked at 72 MHz.
Rated for -40 to 105 °C ambient, this MCU operates from 1.71 to 3.6 V supply.
The DMA controller offloads the CPU for high-rate ADC scanning or serial data streaming. The LVD and POR blocks handle brown-out supervision without an external supervisor IC.
The MK20DX128VLH7 is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
Within the Kinetis K20 family, the MK20DX256VLH7 (256 KB Flash) is pin-compatible and a direct drop-in for higher memory needs. The MK20DN128VLH7 (no USB) shares the same footprint but lacks the USB OTG peripheral.
The core runs at 72 MHz, based on the ARM Cortex-M4 with single-cycle MAC and FPU.
