Product details
Overview
MKL16Z64VLH4 from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ based microcontroller in 64-pin LQFP package, featuring 64 KB flash, 8 KB SRAM, and up to 54 GPIOs. It delivers ultra-low-power operation (as low as 0.23 µA in VLLS0 mode), integrated 16-bit SAR ADC and 12-bit DAC, and supports nine low-power modes - ideal for battery-powered industrial sensors and portable HMI devices.
For engineers reviewing the MKL16Z64VLH4 datasheet, MKL16Z64VLH4 pinout, MKL16Z64VLH4 application, or MKL16Z64VLH4 equivalent, key selection criteria include its 48 MHz Cortex-M0+ core, -40°C to +105°C extended temperature range, 1.71–3.6 V supply voltage, 64-pin LQFP mechanical compatibility, and verified support for I²C, SPI, UART, I²S, TSI, and RTC peripherals.
Technical Context
The MKL16Z64VLH4 implements a multi-clock architecture with MCG supporting FEI, FBE, BLPI, and BLPE modes, enabling dynamic switching between high-performance (48 MHz) and ultra-low-power (4 MHz) run states. Its power management unit integrates clock gating, voltage scaling, and nine configurable low-power modes including VLLS0 (0.23 µA), VLPS (2.69 µA), and STOP (305 µA).
Peripherals are partitioned across power domains: analog modules (ADC, DAC, CMP) operate from dedicated VDDA, while digital logic uses VDD; the TSI module supports capacitive touch sensing without external components, and the Bit Manipulation Engine accelerates bit-field operations in firmware.

FAQ
What is the maximum operating frequency of the MKL16Z64VLH4 core?
The MKL16Z64VLH4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achieved using the MCG in PEE mode with an external crystal or internal FLL; the core remains fully functional at lower frequencies (down to 4 MHz in VLPR mode) to optimize power consumption for background tasks.
Does the MKL16Z64VLH4 support hardware touch sensing?
Yes, the MKL16Z64VLH4 integrates a dedicated Touch Sensing Input (TSI) module capable of driving up to 16 capacitive touch electrodes without external components. It includes built-in calibration, noise filtering, and low-power scanning - enabling robust touch buttons, sliders, or wheels in battery-operated devices.
What are the low-power modes supported by the MKL16Z64VLH4?
The MKL16Z64VLH4 supports nine distinct low-power modes: RUN, WAIT, STOP, VLPS, LLS, VLLS0, VLLS1, VLLS2, and VLLS3. The deepest mode, VLLS0, draws just 0.23 µA at 3.0 V while retaining full register state and RAM contents, with a 4.5 µs wake-up time - ideal for interrupt-driven sensor wake-up scenarios.
Can the MKL16Z64VLH4 operate across the full industrial temperature range?
Yes, the MKL16Z64VLH4 is specified for ambient operating temperatures from -40°C to +105°C. This extended range is validated per JEDEC JESD22-A108 and supports deployment in demanding environments such as automotive under-hood modules, industrial PLC I/O cards, and outdoor environmental monitoring equipment.
What communication interfaces are available on the MKL16Z64VLH4?
The MKL16Z64VLH4 provides two UART modules (including one low-power UART), two I²C modules, two SPI modules, one I²S/SAI audio interface, and a dedicated low-power timer (LPTMR) for precise timekeeping - all accessible via multiplexed GPIO pins and configurable through the SIM and PORT modules.
