NXP Semiconductors MKL16Z128VFT4

Overview

MKL16Z128VFT4 from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ microcontroller in 48-pin QFN (7 × 7 mm, 0.5 mm pitch), featuring 128 KB flash, 16 KB SRAM, and ultra-low-power operation down to 0.4 µA in VLLS0 mode with full state retention - deployed in battery-powered industrial sensors and portable medical devices requiring deterministic wake-up and secure firmware execution.

For engineers reviewing the MKL16Z128VFT4 datasheet, MKL16Z128VFT4 pinout, MKL16Z128VFT4 application, or MKL16Z128VFT4 equivalent, key selection criteria include its 9 low-power modes, integrated 16-bit SAR ADC + 12-bit DAC, TSI touch interface, dual UART/I²C/SPI support, and AEC-Q100 Grade 2 qualification for extended temperature operation (–40 to 105°C).

Technical Context

The MKL16Z128VFT4 implements a tightly coupled Cortex-M0+ core with Bit Manipulation Engine and Micro Trace Buffer, paired with a multi-gated 90nm TFS process enabling zero-wait-state flash access and dynamic clock/power gating. Its MCG clock system supports FEI/FBI/BLPI/PEE modes with internal 4 MHz IRC and external 32 kHz/4–16 MHz crystal options.

System-level power optimization includes nine configurable low-power modes (RUN/VLPR/STOP/VLPS/LLS/VLLS0–3), COP watchdog, low-leakage wakeup unit, and SWD debug interface - all coordinated via SMC and PMC modules to achieve sub-µA static current while retaining RAM, registers, and peripheral states.

FAQ

What is the maximum operating frequency and process technology of the MKL16Z128VFT4?

The MKL16Z128VFT4 operates at a maximum core frequency of 48 MHz using an ARM Cortex-M0+ processor fabricated on NXP's 90 nm TFS (Thin Film Silicon) process. This technology enables aggressive clock and power gating, zero-wait-state flash access, and industry-leading energy efficiency - verified in the official NXP datasheet Rev. 7 (October 2023). The MKL16Z128VFT4 achieves 32.3 CoreMark/MHz under benchmark conditions.

Does the MKL16Z128VFT4 support hardware touch sensing, and how many channels are available?

Yes, the MKL16Z128VFT4 integrates a dedicated hardware Touch Sensing Interface (TSI) module supporting up to 16 capacitive sensing channels. It operates independently of the CPU, enabling low-power touch detection during VLPR or STOP modes. The TSI includes built-in charge/discharge circuitry and noise filtering - confirmed in Section 3.9.1 of the KL16 Reference Manual. This capability is fully implemented in the MKL16Z128VFT4 and requires no external components.

What are the lowest power consumption modes supported by the MKL16Z128VFT4, and what is the typical current draw?

The MKL16Z128VFT4 supports nine low-power modes, with VLLS0 (Very-Low-Leakage Stop Mode 0) delivering the lowest static current: 0.23 µA at 25°C and 3.0 V when PORPO = 1 (no brownout detection). Full register and RAM state are retained, and wake-up occurs in 4.5 µs. These values are measured per Table 9 in the NXP Kinetis KL16 Sub-Family datasheet Rev. 7. The MKL16Z128VFT4 achieves this via deep power gating and optimized leakage control in its 90 nm TFS process.

Which communication interfaces are integrated into the MKL16Z128VFT4, and are they all accessible on the 48-pin QFN package?

The MKL16Z128VFT4 integrates two UARTs, two I²C modules, two SPI modules, and one I²S/SAI audio interface - all fully routed to the 48-pin QFN package (VFT4 suffix). Pin assignments are documented in Section 5.2 "KL16 pinouts" of the datasheet, confirming availability of UART0/1, I²C0/1, SPI0/1, and SAI0 signals on dedicated pins. No interface is disabled or multiplexed out in this variant - the MKL16Z128VFT4 maintains full peripheral accessibility within its compact footprint.

Is the MKL16Z128VFT4 qualified for automotive applications, and what temperature range does it support?

Yes, the MKL16Z128VFT4 is qualified to AEC-Q100 Grade 2 (–40 to +105°C ambient), making it suitable for automotive body electronics and industrial environments. Its specified operating temperature range is –40°C to +105°C, with validated performance across voltage (1.71–3.6 V) and thermal extremes - confirmed in Table 15 "Thermal operating requirements" and Section 6 "Ordering parts" of the NXP datasheet. This qualification applies directly to the MKL16Z128VFT4 part number.
