Product details

Compact Cortex-M4 with USB and industrial temperature range

The MK20DX32VFM5: 32-bit ARM Cortex-M4 MCU at 50 MHz with 32 KB Flash, 8 KB RAM, 2 KB EEPROM, USB OTG, and 6-channel 16-bit ADC.

50 MHz Cortex-M4 — what it buys the BOM

The DSP extension and floating-point unit (FPU) are absent on this Cortex-M4 — it is the single-precision FPU-less variant, so keep that in mind if your algorithm relies on hardware float.

Peripheral set and I/O budget

Twenty I/O pins with I²C, SPI, UART, IrDA, and USB OTG connectivity. Six-channel 16-bit ADC and DMA offload the CPU.

Lifecycle status is Active. No last-time-buy or NRND flag. Available through independent distribution.

Frequently asked questions

What is the MK20DX32VFM5 operating temperature range?

The MK20DX32VFM5 is rated for -40°C to 105°C ambient, covering industrial and extended-temperature environments.

What is the operating voltage of MK20DX32VFM5?

The supply voltage range is 1.71 V to 3.6 V, allowing operation from a single 3.3 V rail or a 1.8 V battery with a boost converter.

What is the closest pin-compatible alternative to MK20DX32VFM5?

Pin-compatible density upgrades within the Kinetis K20 family — MK20DX64VFM5 (64 KB Flash) and MK20DX128VFM5 (128 KB Flash) — share the same 32-QFN-EP footprint and peripheral set. Firmware migration requires only a memory map adjustment.
