Product details

The NXP MKL46Z256VLH4 is a Kinetis KL4 series ARM Cortex-M0+ 32-bit MCU clocked at 48 MHz, with 256 KB Flash and 32 KB RAM. The 64-LQFP package gives you 50 GPIOs. Operating from 1.71 V to 3.6 V across -40 to 105 °C, it fits industrial control panels, HMI front-ends, sensor nodes, and battery-powered instrumentation where USB host/peripheral connectivity is needed without an external PHY.

The 48 MHz core handles real-time control loops and protocol bridging without a co-processor. The 256 KB Flash supports a USB stack or graphics library.

Frequently asked questions

What is the closest pin-compatible alternative to MKL46Z256VLH4?

The MKL46Z128VLH4 (128 KB Flash) is pin-compatible in the same 64-LQFP footprint. The MKL46Z256VLL4 (100-LQFP) shares the same core and memory but has a different pin count and more I/O.

Does MKL46Z256VLH4 have an internal oscillator?

Yes, it includes an internal oscillator, so you can run without an external crystal for cost-sensitive designs.

What is MKL46Z256VLH4's listed speed?

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