Product details

The MK20DX256VMD10 is a 32-bit ARM Cortex-M4 MCU from the Kinetis K20 series, clocked at 100 MHz with 256 KB of Flash, 64 KB of RAM, and 4 KB of EEPROM.

Peripherals and connectivity — what is on chip

The MK20DX256VMD10 integrates a 42-channel 16-bit ADC and a 2-channel 12-bit DAC, which covers multi-sensor acquisition and analog output without external converters. The USB OTG with on-chip transceiver simplifies a device/host/OTG port to a single connector and a few passives. The EBI is useful if you need to attach an external SRAM or a parallel LCD controller, but it consumes 20+ I/Os — plan the pin allocation against the 100 available GPIOs. DMA, I²S, and a programmable watchdog timer are also on board.

Frequently asked questions

What is the difference between MK20DX256VMD10 and MK20DX128VMD10?

The only difference is the Flash memory size: the MK20DX256VMD10 has 256 KB, while the MK20DX128VMD10 has 128 KB. Both share the same 144-MAPBGA package, pinout, 100 MHz Cortex-M4 core, 64 KB RAM, and peripheral set, making them pin-compatible for a drop-in swap.

Where can I buy MK20DX256VMD10?

The MK20DX256VMD10 is sourced and quoted to order against an RFQ through our independent distribution desk. Availability and current pricing are confirmed at quote time — submit an RFQ for a competitive price and lead time.

What is MK20DX256VMD10's listed speed?

The core processor runs at 100 MHz. This is the maximum clock frequency for the ARM Cortex-M4 core; the bus clock and peripheral clocks are configurable via the system clock divider.

What is the pinout of MK20DX256VMD10?

The pinout is defined for the 144-MAPBGA package. The exact ball assignment is available in the NXP MK20DX256 reference manual and datasheet. The part shares the same pinout as the MK20DX128VMD10, so that document covers both.
