It features 128 KB on-chip flash, 16 KB RAM, 32 KB FlexNVM, operates from 1.71–3.6 V, supports –40 to 105°C ambient temperature, and delivers 1.25 Dhrystone MIPS/MHz at up to 50 MHz core frequency.

For engineers reviewing the MK20DX128VMP5 datasheet, MK20DX128VMP5 pinout, MK20DX128VMP5 application, or MK20DX128VMP5 equivalent, key selection considerations include its FlexMemory architecture (separate 32 KB FlexNVM + 2 KB FlexRAM), USB On-The-Go controller with integrated transceiver, 16-bit SAR ADC, dual analog comparators with 6-bit DACs, and support for eight low-power modes including VLLS0 with sub-μA stop current.

Technical Context

The MK20DX128VMP5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, enabling efficient motor control and audio preprocessing. Its clock system integrates a multi-purpose clock generator (MCG) supporting internal/external oscillators (3–32 MHz crystal, 32 kHz RTC crystal), PLL, and fine-grained peripheral clock gating.

Peripherals include a full-speed USB OTG controller with on-chip transceiver, three UARTs, two I²C modules, two SPI interfaces, I²S, eight-channel PWM timer, quadrature decoder, real-time clock, and programmable delay block - all accessible via configurable pin multiplexing in the 64-pin MAPBGA package.

FAQ

What is the maximum operating frequency of the MK20DX128VMP5?

The MK20DX128VMP5 operates at a maximum core frequency of 50 MHz. This is achieved using the internal PLL driven by the main crystal oscillator (EXTAL0/XTAL0). The system clock (fSYS), bus clock (fBUS), and flash clock (fFLASH) are derived from this source, with fFLASH limited to 25 MHz for reliable flash access timing. The MK20DX128VMP5 maintains full functionality-including USB, ADC, and DMA-at this speed under specified voltage (1.71–3.6 V) and temperature (–40 to 105°C) conditions.

Does the MK20DX128VMP5 include an integrated USB transceiver?

Yes, the MK20DX128VMP5 includes a full-speed/low-speed USB On-The-Go controller with an integrated transceiver. This eliminates the need for an external USB PHY chip. The USB_DP and USB_DM pins connect directly to the USB connector, and the internal USB voltage regulator (VREGIN) accepts 3.0–3.6 V input. The MK20DX128VMP5 supports USB device, host, and OTG roles, and complies with USB 2.0 specification for full-speed (12 Mbps) and low-speed (1.5 Mbps) operation.

What memory types are available on the MK20DX128VMP5?

The MK20DX128VMP5 provides 128 KB of program flash memory, 16 KB of general-purpose SRAM, 32 KB of FlexNVM, and 2 KB of FlexRAM. FlexNVM can be configured as data flash (for EEPROM emulation) or additional program flash; FlexRAM serves as user-accessible RAM that retains data during certain low-power modes. Unlike standard flash, FlexNVM supports byte-level erase and >100,000 write cycles - a key differentiator of the MK20DX128VMP5 within the K20 family.

What is the operating temperature range for the MK20DX128VMP5?

The MK20DX128VMP5 is rated for an ambient operating temperature range of –40 to 105°C. This is indicated by the "V" suffix in the part number (MK20DX128VMP5). The device meets industrial and extended-temperature automotive requirements, supporting reliable operation in under-hood, motor drive, and industrial control environments. All electrical specifications - including flash programming, ADC accuracy, and USB timing - are guaranteed across this full range when supplied within the 1.71–3.6 V voltage window.

How does the MK20DX128VMP5 support low-power design?

The MK20DX128VMP5 supports seven low-power modes, including VLLS0 (Very-Low-Leakage Stop mode 0) with typical current draw of 0.37 μA at –40°C. Key enablers include the low-leakage wakeup unit, programmable brown-out detection, and independent clock gating per peripheral. In VLLS0, the POR circuit remains active while most logic is powered down - allowing wake-up via RTC alarm, GPIO, or LLWU inputs. The MK20DX128VMP5 also offers VLPR (Very-Low-Power Run) mode at 4 MHz, drawing just 867 μA, enabling background processing during extended sleep intervals.
