Product details

48 MHz Cortex-M0+ with USB — compact industrial MCU

The NXP MKL27Z128VFM4 is a 32-bit ARM Cortex-M0+ microcontroller from the Kinetis KL2 series, clocked at 48 MHz with 128 KB Flash and 32 KB RAM. It integrates a full-speed USB controller alongside I²C, SPI, and UART/USART serial interfaces.

The 32 KB RAM handles double-buffered USB endpoints and a few hundred bytes of packet data; designs streaming continuous ADC samples over USB should budget RAM for a circular buffer. The internal oscillator trims to within 1–2% accuracy, sufficient for USB full-speed timing without an external crystal in many applications.

Frequently asked questions

What is MKL27Z128VFM4's listed speed?

The core runs at 48 MHz, which is the maximum clock for the ARM Cortex-M0+ in this Kinetis KL2 variant.

What is the closest pin-compatible alternative to MKL27Z128VFM4?

The Kinetis KL2 family includes pin-compatible density options such as MKL27Z64VFM4 (64 KB Flash) and MKL27Z256VFM4 (256 KB Flash) in the same 32-HUQFN package, allowing a memory upgrade without a PCB change.
