Product details
Overview
MKL04Z16VLC4 from NXP Semiconductors (formerly Freescale) is an ultra-low-power 32-bit ARM Cortex-M0+ microcontroller designed for cost-sensitive, battery-powered embedded systems. It operates at up to 48 MHz core frequency, integrates 16 KB flash and 2 KB SRAM, features a 12-bit SAR ADC with 14 single-ended channels, one analog comparator with four inputs, and supports multiple low-power modes including VLPS and STOP. It is used in portable medical sensors and smart metering endpoints requiring long runtime and reliable mixed-signal operation.
For engineers reviewing the MKL04Z16VLC4 datasheet, MKL04Z16VLC4 pinout, MKL04Z16VLC4 application, or MKL04Z16VLC4 equivalent, key selection criteria include its 32-pin LQFP package, 4-channel DMA support, real-time clock (RTC), 64-byte cache, and compatibility with Kinetis KL0x development tools and MCUXpresso IDE.
Technical Context
The MKL04Z16VLC4 implements a 48 MHz ARM Cortex-M0+ core with two-stage pipeline and zero-wait-state flash execution, enabling efficient interrupt response and low CPI. Its system architecture includes a 64-byte cache, integrated Bit Manipulation Engine (BME), and Micro Trace Buffer (MTB) for lightweight debug trace.
It integrates a full-featured power management controller supporting 10 low-power modes, a 32 kHz–32 MHz crystal oscillator interface, FLL-based clock generation (20–48 MHz), and peripherals including one 6-channel + one 2-channel TPM, one 32-bit PIT, one LPTMR, one RTC, and one low-power UART - all operable in low-power states without waking the CPU.
Key Specifications

FAQ
What is the maximum operating frequency and voltage range for MKL04Z16VLC4?
The MKL04Z16VLC4 operates at a maximum core frequency of 48 MHz across its full supply voltage range of 1.71 V to 3.6 V. Flash programming and analog peripherals remain fully functional down to 1.71 V, and the device supports ambient temperatures from –40 °C to +105 °C in its 32-pin LQFP package. This makes MKL04Z16VLC4 suitable for industrial-grade portable equipment.
Does MKL04Z16VLC4 include a real-time clock (RTC) and how is it powered in low-power modes?
Yes, MKL04Z16VLC4 includes a 32-bit real-time clock (RTC) with calendar functionality. The RTC remains operational in STOP and VLPS low-power modes using either the internal 1 kHz LPO or an external 32.768 kHz crystal connected to RTC_CLKIN. This allows MKL04Z16VLC4 to maintain accurate timekeeping and generate periodic wake-up interrupts without CPU intervention.
How many ADC channels does MKL04Z16VLC4 support and what resolution options are available?
MKL04Z16VLC4 features a 12-bit successive approximation ADC with up to 14 single-ended input channels, including one dedicated temperature sensor channel. It supports configurable resolution modes (12-bit, 10-bit, 8-bit), right-aligned unsigned output format, and hardware averaging. The ADC operates independently in low-power modes, enabling MKL04Z16VLC4 to perform sensor measurements without waking the core.
Is MKL04Z16VLC4 pin-compatible with other Kinetis L series MCUs in the same package?
Yes, MKL04Z16VLC4 is pin-compatible with all other KL0x family members offered in the 32-pin LQFP (LC) package, including MKL04Z8VLC4, MKL04Z32VLC4, MKL05Z16VLC4, and MKL05Z32VLC4. This allows hardware reuse and migration paths within the Kinetis L portfolio while preserving PCB layout and signal routing integrity.
What debug interface does MKL04Z16VLC4 support and is trace capability included?
MKL04Z16VLC4 supports 2-pin Serial Wire Debug (SWD) for programming and real-time debugging. It also includes a Micro Trace Buffer (MTB) that uses on-chip SRAM to capture instruction trace data - enabling non-intrusive analysis of program flow and ISR timing without requiring external debug probes or additional pins.
