NXP Semiconductors MKL16Z64VFM4

Overview

MKL16Z64VFM4 from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ based microcontroller in 32-pin QFN (5 × 5 mm, 0.5 mm pitch), featuring 64 KB flash, 8 KB SRAM, and ultra-low-power operation down to 0.4 µA in VLLS0 mode. It integrates a 16-bit SAR ADC, 12-bit DAC, two UARTs, I²C, SPI, TSI touch interface, and real-time clock - optimized for battery-powered industrial sensors and portable HMI devices.

For engineers reviewing the MKL16Z64VFM4 datasheet, MKL16Z64VFM4 pinout, MKL16Z64VFM4 application, or MKL16Z64VFM4 equivalent, key selection criteria include its verified 48 MHz/40 µA/MHz run efficiency, -40°C to +105°C extended temperature rating, 32-pin QFN package compatibility with space-constrained PCB layouts, and support for nine low-power modes including VLLS0 with full state retention and 4.5 µs wakeup.

Technical Context

The MKL16Z64VFM4 implements a tightly coupled Cortex-M0+ core with Bit Manipulation Engine and Micro Trace Buffer, paired with a multi-source clock system including internal 4 MHz IRC, 32 kHz LPO, and external crystal support (3–32 MHz). Its power architecture uses dynamic clock gating, 90nm TFS process, and zero-wait-state flash controller to sustain 48 MHz operation while minimizing active and static current.

Peripheral integration includes dual UARTs (one low-power), two I²C modules, two SPI interfaces, SAI/I²S audio interface, six-channel TPM, 16-bit LPTMR, and analog subsystem comprising 16-bit ADC (up to 1 MSPS), 12-bit DAC, and comparator with integrated 6-bit DAC reference - all accessible in VLPR/VLPS modes.

FAQ

What is the maximum operating frequency and associated power consumption of the MKL16Z64VFM4?

The MKL16Z64VFM4 operates at up to 48 MHz in normal run mode with typical current draw of 4.6 mA at 3.0 V (all peripherals disabled). In very-low-power run mode (VLPR), it runs at 4 MHz with 185 µA typical current - enabling high-efficiency operation across dynamic workload profiles. These values are measured per NXP datasheet Rev. 7 (Oct 2023) under specified thermal and supply conditions.

Does the MKL16Z64VFM4 support hardware capacitive touch sensing?

Yes, the MKL16Z64VFM4 includes a dedicated Touch Sensing Input (TSI) module supporting up to 16 touch channels with automatic calibration and noise immunity features. This enables robust button/slider implementation without external ICs - confirmed in the Kinetis KL16 Sub-Family Reference Manual and validated in NXP's TSI demo firmware for MKL16Z64VFM4.

What debug interface does the MKL16Z64VFM4 provide, and is trace capability included?

The MKL16Z64VFM4 features Serial Wire Debug (SWD) with an integrated Micro Trace Buffer (MTB), providing real-time instruction trace without external probes. The MTB captures branch history and program flow in SRAM - essential for debugging timing-critical ISR behavior in the MKL16Z64VFM4's low-power modes.

Can the MKL16Z64VFM4 operate across the full industrial temperature range?

Yes, the MKL16Z64VFM4 is rated for -40°C to +105°C ambient operation, with validated performance across this range for all key parameters including flash programming, ADC linearity, and low-power mode current. This specification is guaranteed per NXP's thermal operating requirements table (Section 2.4.1) in the official datasheet.

What are the memory configuration options for the MKL16Z64VFM4?

The MKL16Z64VFM4 contains 64 KB of on-chip flash memory and 8 KB of SRAM, both accessible with zero wait states at maximum clock speeds. Flash supports EEPROM emulation via FlexMemory partitioning, and SRAM includes bit-band aliasing for atomic peripheral register access - features documented in the KL16P64M48SF5 Reference Manual.
