NXP Semiconductors MKL16Z64VFT4R

Overview

MKL16Z64VFT4R from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ microcontroller in 48-pin QFN (7 × 7 mm, 0.5 mm pitch), featuring 64 KB flash, 8 KB SRAM, and up to 40 GPIOs. It delivers ultra-low-power operation down to 0.23 µA in VLLS0 mode with full state retention and 4.5 µs wakeup, targeting battery-powered industrial sensors and portable medical devices.

For engineers reviewing the MKL16Z64VFT4R datasheet, MKL16Z64VFT4R pinout, MKL16Z64VFT4R application, or MKL16Z64VFT4R equivalent, key selection criteria include its 48 MHz Cortex-M0+ core, 16-bit SAR ADC + 12-bit DAC analog integration, dual UART/I²C/SPI interfaces, low-leakage wakeup unit, and support for nine power modes - all validated across –40°C to +105°C ambient operation.

Technical Context

The MKL16Z64VFT4R implements a multi-layer bus architecture with AHB and APB bridges, enabling concurrent peripheral access while maintaining deterministic latency. Its MCG clock system supports multiple modes (FEI, FBE, BLPI, VLPR) with factory-trimmed internal oscillators (1000 µs ±100 µs period) and external crystal support from 32 kHz to 32 MHz.

Power management integrates dynamic voltage scaling, clock gating per peripheral, and dedicated low-power timers (LPTMR) that operate independently in VLPS/VLLS modes. The TSI module provides hardware-accelerated capacitive touch sensing with configurable sensitivity and noise immunity, requiring no CPU intervention during scanning.

FAQ

What is the maximum operating frequency of the MKL16Z64VFT4R core?

The MKL16Z64VFT4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achievable using the MCG in PEE mode with an external crystal or internal reference, and is validated across the full –40°C to +105°C temperature range and 1.71–3.6 V supply. At 48 MHz, the MKL16Z64VFT4R delivers 30.5 CoreMark/MHz performance with cache enabled.

Does the MKL16Z64VFT4R support hardware-accelerated capacitive touch sensing?

Yes, the MKL16Z64VFT4R integrates a dedicated Touch Sensing Interface (TSI) module with hardware scan engine, 16-bit resolution, and automatic calibration. It supports up to 16 electrodes with programmable charge current and noise filtering - enabling robust touch buttons, sliders, or wheels without CPU intervention or external components.

What are the lowest power consumption modes supported by the MKL16Z64VFT4R?

The MKL16Z64VFT4R supports nine low-power modes, with VLLS0 (Very-Low-Leakage Stop Mode 0) delivering the lowest current: 0.23 µA typical at 25°C and 3.0 V when PORPO = 1, retaining full RAM and register state. Wakeup occurs in 4.5 µs via LPTMR, GPIO, or RTC alarm - ideal for infrequent event-driven operation.

Can the MKL16Z64VFT4R operate across the full industrial temperature range?

Yes, the MKL16Z64VFT4R is fully specified and tested for operation from –40°C to +105°C ambient temperature. All electrical characteristics - including flash programming voltage (1.71–3.6 V), ADC accuracy, oscillator stability, and power mode currents - are guaranteed across this range per NXP's KL16P64M48SF5 datasheet Rev. 7.

How many communication interfaces does the MKL16Z64VFT4R provide?

The MKL16Z64VFT4R provides two UART modules (one low-power), two I²C modules, two SPI modules, and one I²S/SAI audio interface. All are accessible via GPIO multiplexing on its 40 usable I/O pins, with independent clock gating and DMA support - enabling simultaneous serial sensor aggregation and wireless protocol bridging.
