MKL16Z256VLH4

MKL16Z256VLH4 is an NXP (Kinetis) L-family microcontroller based on the ARM Cortex-M0+ core. It’s aimed at low-cost, low-power embedded apps, running up to 48 MHz with 256 KB of flash and about 32 KB of SRAM. On-chip peripherals typically include multiple GPIOs, a 12‑bit ADC, PWM/timers, and serial interfaces (USART/UART, I2C, SPI); some variants may offer USB device capability. It supports a wide supply range (roughly 1.71–3.6 V) and several power/low-power modes ideal for battery-powered designs. The VLH4 suffix identifies the specific package/variant of this part. Development is supported by MCUXpresso IDE and the Kinetis SDK. Common use cases include sensor hubs, IoT nodes, consumer electronics, and other cost-sensitive control tasks.
