Product details
Overview
MKL03Z8VFG4R from NXP Semiconductors is an ARM Cortex-M0+ microcontroller in a 16-pin QFN (3 × 3 mm, 0.5 mm pitch) package, featuring 8 KB flash, 2 KB SRAM, and operation up to 48 MHz. It delivers ultra-low-power performance with 77 nA deep-sleep current, 2.2 µA static retention mode, and 7.5 µs wake-up time-ideal for battery-powered IoT edge nodes requiring minimal footprint and extended runtime.
For engineers reviewing the MKL03Z8VFG4R datasheet, MKL03Z8VFG4R pinout, MKL03Z8VFG4R application, or MKL03Z8VFG4R equivalent, key selection criteria include its 16-pin QFN thermal profile (–40 to 105°C), integrated 12-bit ADC (818 ksps, 7 channels), LPUART/I²C/SPI interfaces, and support for nine low-power modes including VLLS0/VLLS3.
Technical Context
The MKL03Z8VFG4R implements an ARM Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB) for efficient debug and code execution. Its clock system integrates a 48 MHz high-accuracy internal reference (HIRC), 8/2 MHz low-power oscillator (LIRC), and 32–40 kHz crystal support-enabling precise timing across run, wait, and stop power modes.
System-level integration includes a boot ROM with built-in bootloader, 1.2 V internal voltage reference (VREF), 80-bit unique chip ID, and a low-leakage wakeup unit. Analog functionality centers on a 12-bit SAR ADC with internal reference and a high-speed comparator with embedded 6-bit DAC-supporting sensor signal conditioning without external components.

Does MKL03Z8VFG4R include a factory-programmed bootloader?
Yes, MKL03Z8VFG4R contains 8 KB of ROM with a factory-programmed bootloader supporting UART and I²C interfaces. This enables firmware updates in the field without JTAG or external programming hardware. The bootloader is accessible after reset when the BOOTCFG pin is asserted, and its presence is documented in the KL03 Reference Manual KL03P24M48SF0RM1 section 3.4.1.
What ADC resolution and sampling rate does MKL03Z8VFG4R support?
MKL03Z8VFG4R integrates a 12-bit SAR ADC capable of up to 818 ksps with 7 input channels. It includes an internal 1.2 V voltage reference (VREF) with ±1.5% accuracy, enabling ratiometric measurements independent of supply variation. These specifications are measured and guaranteed across the full –40°C to 105°C temperature range per Table 3.6.1 in the KL03 datasheet.
How many GPIO pins are available on MKL03Z8VFG4R?
MKL03Z8VFG4R provides 14 GPIO pins, all multiplexed with peripheral functions including UART0, I²C0, SPI0, ADC inputs, and timer PWM outputs. Pin assignments are fixed per the 16-pin QFN package layout and are fully documented in Section 5.2 "KL03 pinouts" of the KL03P24M48SF0 datasheet. No additional GPIOs are available beyond these 14.
What low-power modes are supported by MKL03Z8VFG4R?
MKL03Z8VFG4R supports nine distinct low-power modes, including RUN, WAIT, STOP, VLPS, and VLLS0–VLLS3. The deepest mode, VLLS0, achieves 77 nA at 3.0 V with full RAM retention and 7.5 µs wake-up time.
