NXP Semiconductors MKL16Z64VFM4R

Overview

MKL16Z64VFM4R from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ 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, two I²C, two SPI, I²S/SAI, TSI touch interface, and six-channel TPM - optimized for battery-powered industrial sensors and portable HMI devices.

For engineers reviewing the MKL16Z64VFM4R datasheet, MKL16Z64VFM4R pinout, MKL16Z64VFM4R application, or MKL16Z64VFM4R equivalent, key selection criteria include its 48 MHz Cortex-M0+ core, -40°C to +105°C operating range, 1.71–3.6 V supply, nine low-power modes, and QFN32 package compatibility with space-constrained embedded designs.

Technical Context

The MKL16Z64VFM4R implements an energy-optimized Cortex-M0+ core with Bit Manipulation Engine and Micro Trace Buffer for debug visibility. Its clock system supports multiple sources including internal 4 MHz/32 kHz IRC, external crystal (3–32 MHz), and PLL-based 48 MHz PEE mode - all managed via the Multipurpose Clock Generator (MCG).

Power management includes nine configurable low-power modes (VLPR, VLPS, LLS, VLLS0–3), with full state retention at 2 µA and 4.5 µs wakeup from VLPS. Peripheral clock gating, dynamic voltage scaling, and zero-wait-state flash controller enable deterministic real-time execution while minimizing active and static power.

FAQ

What is the maximum operating frequency of the MKL16Z64VFM4R core?

The MKL16Z64VFM4R features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achieved using the Phase-Locked Loop (PLL) with the Multipurpose Clock Generator (MCG) in PEE mode. In ultra-low-power run (VLPR) mode, the core operates up to 4 MHz to minimize active current consumption while retaining full register state.

Does the MKL16Z64VFM4R support hardware touch sensing?

Yes, the MKL16Z64VFM4R includes a dedicated Low-Power Hardware Touch Sensor Interface (TSI) module capable of scanning up to 16 electrodes with less than 1 µA standby current. It supports self-capacitance measurement and automatic calibration, eliminating the need for external touch controllers in applications such as control panels and wearable interfaces.

What are the supported low-power modes for MKL16Z64VFM4R and their typical current draw?

The MKL16Z64VFM4R supports nine low-power modes. Key examples include VLPR (185 µA typical), VLPS (2.69 µA at 25°C), LLS (1.98 µA), and VLLS0 (0.23 µA with PORPO=1). Each mode offers trade-offs between wakeup latency (as low as 4.5 µs from VLPS) and current consumption, enabling precise power optimization for intermittent-sensing applications.

Can MKL16Z64VFM4R operate across the full industrial temperature range?

Yes, the MKL16Z64VFM4R is specified for ambient operating temperatures from -40°C to +105°C. This rating is validated across all electrical parameters including flash programming, ADC accuracy, and clock stability - making it suitable for deployment in harsh environments such as factory automation controllers and automotive cabin modules.

What debug interface does MKL16Z64VFM4R provide?

The MKL16Z64VFM4R implements a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, plus an integrated Micro Trace Buffer (MTB) for real-time instruction trace without halting the CPU. This enables non-intrusive debugging of time-critical firmware, such as motor control loops or sensor sampling routines, directly in the MKL16Z64VFM4R target environment.
