FAQ

What is the maximum operating frequency of the MKL16Z128VFT4R core?

The MKL16Z128VFT4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achievable using the internal FLL or external crystal with proper clock configuration (e.g., PEE mode). In very-low-power run (VLPR) mode, the core operates up to 4 MHz to minimize dynamic power consumption while retaining full code execution capability. The MKL16Z128VFT4R datasheet specifies fSYS ≤ 48 MHz as the absolute maximum system clock frequency under all valid operating conditions.

Does the MKL16Z128VFT4R support hardware touch sensing?

Yes, the MKL16Z128VFT4R includes a dedicated Low-Power Hardware Touch Sensor Interface (TSI) module capable of driving up to 16 electrodes with automatic scanning, noise filtering, and baseline tracking. It operates with <1 µA active current in touch-sense mode and supports proximity, button, slider, and wheel configurations. The TSI is fully integrated into the MKL16Z128VFT4R silicon - no external RC networks or dedicated touch controller ICs are required, reducing BOM cost and PCB area.

What are the lowest power consumption modes supported by the MKL16Z128VFT4R?

The MKL16Z128VFT4R supports nine low-power modes, with VLLS0 (Very-Low-Leakage Stop Mode 0) offering the deepest sleep state at 0.23 µA (typical, 25°C, PORPO=1) while retaining full RAM and register contents. VLLS1 draws 0.71 µA and supports limited wake-up sources, while VLPS (Very-Low-Power Stop) consumes 2.69 µA and allows faster 4.5 µs wakeup. All modes are accessible via the SMC module and validated across the -40 to 105°C temperature range specified for the MKL16Z128VFT4R.

Can the MKL16Z128VFT4R operate from a single 1.8 V supply?

Yes, the MKL16Z128VFT4R is fully specified to operate across a 1.71–3.6 V supply range, including stable operation at 1.8 V. At this voltage, the maximum core frequency is reduced to approximately 24 MHz (per clock specification tables), and analog performance (ADC/DAC accuracy, reference stability) remains within datasheet limits. The MKL16Z128VFT4R's wide voltage range enables direct interfacing with 1.8 V logic families and simplifies power architecture in multi-rail systems.

What debug interface does the MKL16Z128VFT4R provide?

The MKL16Z128VFT4R uses a 2-pin Serial Wire Debug (SWD) interface - SWD_DIO and SWD_CLK - compliant with ARM CoreSight standards. This interface supports full-speed programming, real-time debugging, memory inspection, and Micro Trace Buffer (MTB) streaming without halting the CPU. No JTAG header is required; standard ARM SWD debug probes (e.g., NXP LPC-Link2, SEGGER J-Link) are compatible out-of-the-box with the MKL16Z128VFT4R.
