Product details
Overview
MKL16Z64VFT4 from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ based microcontroller in 48-pin QFN (7 × 7 mm, 0.5 mm pitch), featuring 64 KB flash, 8 KB SRAM, and ultra-low-power operation down to 2 μA in VLLS0 mode with full state retention. It integrates a 16-bit SAR ADC, 12-bit DAC, two UARTs, two I²C modules, two SPIs, I²S/SAI, TSI touch interface, and six-channel TPM - optimized for battery-powered industrial sensors and portable HMI devices.
For engineers reviewing the MKL16Z64VFT4 datasheet, MKL16Z64VFT4 pinout, MKL16Z64VFT4 application, or MKL16Z64VFT4 equivalent, key selection criteria include its 48-pin QFN package compatibility, -40°C to +105°C extended temperature range, 1.71–3.6 V supply voltage, nine low-power modes, and support for SWD debug with Micro Trace Buffer - critical for energy-constrained embedded designs requiring rapid wake-up (<5 μs from VLPS/STOP) and mixed-signal integration.
Technical Context
The MKL16Z64VFT4 implements a tightly coupled Cortex-M0+ core with Bit Manipulation Engine and hardware divide, paired with a zero-wait-state flash controller and clock/power gating architecture built on 90 nm TFS technology. Its MCG clock system supports multiple modes including FEI, FBE, BLPI, and PEE, enabling dynamic switching between 48 MHz run and 4 MHz VLPR operation.
System-level integration includes a 4-channel DMA supporting 63 request sources, low-leakage wakeup unit with configurable pins, COP watchdog, and LPUART with 16× oversampling. Analog subsystem comprises a 16-bit SAR ADC with programmable gain amplifier, 12-bit DAC, and analog comparator with integrated 6-bit DAC reference - all operating across the full 1.71–3.6 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKL26Z64VFT4 | Same KL family, adds USB OTG controller and higher ADC sample rate (1.2 MSPS); 128 KB flash option available. | Better suited for USB-connected diagnostic tools or firmware-upgradable field devices. | Select MKL26Z64VFT4 only if native USB device functionality is required; otherwise MKL16Z64VFT4 offers lower cost and identical power/performance for non-USB use cases. |
| STM32L071KBT6 | ARM Cortex-M0+, 32 MHz max, 128 KB flash, 20 KB SRAM; different pinout (32-pin LQFP), no integrated TSI or SAI. | Preferred for cost-sensitive, low-I/O designs where USB or audio is unnecessary and ST ecosystem tooling is mandated. | Choose STM32L071KBT6 when leveraging ST's CubeMX/LL drivers or when footprint constraints favor 32-pin LQFP over 48-pin QFN. |
Compared with MKL26Z64VFT4 and STM32L071KBT6, the MKL16Z64VFT4 delivers optimal balance of ultra-low-power operation (0.23 µA VLLS0), integrated touch (TSI), and audio-ready peripherals (I²S/SAI) in a compact 48-pin QFN - making it the most direct fit for battery-powered HMI and sensor edge nodes without USB requirements.

FAQ
What is the maximum operating frequency of the MKL16Z64VFT4 core?
The MKL16Z64VFT4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achieved using the MCG's PEE mode with an external crystal and PLL. In very-low-power run (VLPR) mode, the core operates up to 4 MHz - a deliberate trade-off enabling 161 µA typical active current while retaining full code execution capability. The MKL16Z64VFT4's flash controller supports zero wait states at both speeds, ensuring deterministic performance.
Does the MKL16Z64VFT4 support hardware touch sensing?
Yes, the MKL16Z64VFT4 integrates a dedicated hardware Touch Sensing Input (TSI) module capable of driving up to 16 electrodes with 16-bit resolution and built-in noise rejection. It operates independently of the CPU during scanning, allowing touch detection in low-power modes like VLPS and STOP. The TSI module is fully supported in NXP's Kinetis SDK and requires no external components - making it ideal for implementing robust capacitive buttons, sliders, or wheels in the MKL16Z64VFT4-based design.
What are the power consumption characteristics of the MKL16Z64VFT4 in stop mode?
In standard STOP mode, the MKL16Z64VFT4 consumes 305 µA typical (326 µA max) at 25°C and 3.0 V. However, its ultra-low-leakage variants offer significantly lower draw: VLLS0 mode achieves 0.23 µA typical (0.69 µA max) when PORPO = 1, preserving full SRAM and register state. All stop modes retain RTC operation with 32 kHz crystal, and wake-up occurs in ≤5 μs - critical for event-driven applications like occupancy sensing or alarm monitoring where the MKL16Z64VFT4 must respond rapidly after extended sleep.
Which communication interfaces are available on the MKL16Z64VFT4?
The MKL16Z64VFT4 provides two UART modules (including LPUART with 16× oversampling), two I²C modules, two SPI modules, and one I²S/SAI audio interface. All are accessible via dedicated pins on the 48-pin QFN package, with flexible pin multiplexing allowing concurrent use - for example, UART0 for host communication, I²C0 for sensor bus, and SPI0 for display interface. No external transceivers are needed for basic RS-232 or I²C operation, though level-shifting may be required for RS-485 or high-voltage I²C buses interfacing with the MKL16Z64VFT4.
What development tools are officially supported for the MKL16Z64VFT4?
NXP officially supports the MKL16Z64VFT4 with Kinetis SDK v2.x, MCUXpresso IDE (Eclipse-based), and the FRDM-KL25Z and FRDM-KL26Z evaluation boards - both of which share pin-compatible headers and can host the MKL16Z64VFT4 via socket adapter or custom carrier board. Debugging uses standard ARM SWD protocol, compatible with J-Link, CMSIS-DAP, and OpenSDA interfaces. NXP also provides reference designs for touch HMI and sensor fusion that target the MKL16Z64VFT4 directly.
