Product details

72 MHz Cortex-M4 with 256 KB Flash — what it means for the BOM

The NXP MK20DX256VLH7557 is a Kinetis K20 series 32-bit ARM Cortex-M4 MCU clocked at 72 MHz, with 256 KB Flash and 64 KB RAM on a single-core architecture. It carries a full set of peripherals: DMA, I²S, LVD, POR, PWM, and WDT, plus connectivity including CANbus, EBI/EMI, I²C, IrDA, SPI, UART/USART, USB, and USB OTG.

Connectivity and peripherals — what the block can do

The CANbus interface makes this a natural fit for CANopen nodes in mobile equipment or industrial automation. USB OTG allows the MCU to act as either a USB host (flash drive, keyboard) or device (debug, data logging) without an external PHY — useful for field-update or data-harvesting scenarios.

Lifecycle and sourcing

The MK20DX256VLH7557 is listed as Active per the manufacturer lifecycle status. That means it is still in ongoing production with no announced last-time-buy or end-of-life window.

Frequently asked questions

What is the closest pin-compatible alternative to MK20DX256VLH7557?

The Kinetis K20 family includes pin-compatible density variants in the same 64-LQFP package, such as the MK20DX128VLH7 (128 KB Flash / 32 KB RAM) and MK20DX64VLH7 (64 KB Flash / 16 KB RAM). These share the same footprint and peripheral set, allowing a memory-scaled drop-in without a board revision.

What is MK20DX256VLH7557's listed speed?

The MK20DX256VLH7557 is rated for a 72 MHz core speed on the ARM Cortex-M4 processor.
