NXP Semiconductors MKL16Z128VFM4R

Overview

MKL16Z128VFM4R from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ microcontroller in 32-pin QFN (5 × 5 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 monitors.

For engineers reviewing the MKL16Z128VFM4R datasheet, MKL16Z128VFM4R pinout, MKL16Z128VFM4R application, or MKL16Z128VFM4R equivalent, key selection criteria include its 4-channel DMA support, 16-bit SAR ADC with hardware averaging, dual UART + I²C + SPI interfaces, and verified compatibility with Kinetis L-family toolchains and SDKs.

Technical Context

The MKL16Z128VFM4R implements a tightly coupled Cortex-M0+ core with Bit Manipulation Engine and Micro Trace Buffer for real-time debug visibility. Its clock system integrates MCG with FEI/BLPI/PEE modes, supporting internal 4 MHz IRC and external 32 kHz–32 MHz crystals for precise low-power timing control.

Power management includes nine low-power modes (VLPR, VLPS, LLS, VLLS0–3), with sub-µA stop currents and 4.5 µs wakeup from VLPS/STOP - enabled by clock gating, 90nm TFS process, and zero-wait-state flash controller optimized for energy-constrained embedded firmware.

FAQ

What is the maximum operating frequency of the MKL16Z128VFM4R core?

The MKL16Z128VFM4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achievable using the Phase-Locked Loop (PLL) in PEE mode with an external crystal or internal reference clock. At 48 MHz, the device delivers 1.27 CoreMark/MHz performance, validated across the full −40°C to +105°C temperature range and 1.71–3.6 V supply voltage.

Does the MKL16Z128VFM4R support hardware-based capacitive touch sensing?

Yes, the MKL16Z128VFM4R integrates a dedicated Touch Sensing Interface (TSI) module capable of hardware-accelerated capacitive sensing with 16-bit resolution. It supports up to 16 electrodes, automatic baseline tracking, and noise filtering - enabling robust touch buttons, sliders, or wheels without external components or CPU intervention during measurement cycles.

What low-power modes are available on the MKL16Z128VFM4R, and what is the lowest current consumption?

The MKL16Z128VFM4R offers nine low-power modes, including VLLS0 (Very-Low-Leakage Stop Mode 0). In VLLS0 with PORPO = 1, it achieves 0.23 µA typical current at 25°C and 3.0 V while retaining full SRAM and register contents. Wakeup occurs in 4.5 µs from VLPS/STOP and under 120 µs from VLLS0, making it ideal for infrequent-event battery-powered applications.

Can the MKL16Z128VFM4R operate from a single 3.3 V supply across all peripherals?

Yes, the MKL16Z128VFM4R operates across a unified 1.71–3.6 V supply range for both digital (VDD) and analog (VDDA) domains. All peripherals - including the 16-bit ADC, 12-bit DAC, comparators, and communication interfaces - are fully functional within this range. The device specifies VDD-to-VDDA differential tolerance of ±0.1 V, allowing direct connection of VDD and VDDA with proper decoupling.

Is the MKL16Z128VFM4R pin-compatible with other Kinetis L-series MCUs?

No, the MKL16Z128VFM4R is not pin-compatible with other Kinetis L-series MCUs due to its specific 32-pin QFN (VFM4) package and unique pin multiplexing. While it shares identical peripheral register maps, SDK support, and toolchain compatibility with KL1x/KL2x devices, migrating to another package (e.g., VFT4 or VLH4) requires PCB redesign. Functional equivalence exists, but mechanical compatibility does not.
