Product details
Overview
MKL15Z128VLK4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in an 80-pin LQFP package, featuring 128 KB flash, 16 KB SRAM, and ultra-low-power operation down to 0.12 µA in VLLS0 mode with full state retention. It integrates a 16-bit SAR ADC, 12-bit DAC, two UARTs, two I²C modules, two SPI interfaces, TSI touch sensing, and six-channel TPM timers - optimized for battery-powered industrial sensors and portable HMI devices.
For engineers reviewing the MKL15Z128VLK4 datasheet, MKL15Z128VLK4 pinout, MKL15Z128VLK4 application, or MKL15Z128VLK4 equivalent, key selection criteria include its 70 GPIO count, -40°C to +105°C operating range, 1.71–3.6 V supply, 9 low-power modes, and compatibility with Kinetis L-family toolchains and software stacks.
Technical Context
The MKL15Z128VLK4 implements a single-core ARM Cortex-M0+ processor with Micro Trace Buffer and SWD debug interface, executing from zero-wait-state flash memory. Its clock system includes configurable MCG with internal 4 MHz IRC, 32 kHz LPO, and support for external crystals up to 16 MHz in high-frequency mode.
Power management relies on nine distinct low-power modes (RUN, VLPR, STOP, VLPS, LLS, VLLS0–3), each with precise peripheral gating control and wakeup latency as low as 4 µs (VLPS→RUN). The analog subsystem combines a 16-bit ADC with programmable PGA, a 12-bit DAC, and a comparator with integrated 6-bit DAC reference.

Yes, the MKL15Z128VLK4 integrates a dedicated Touch Sensing Input (TSI) module capable of supporting up to 16 capacitive touch electrodes. This hardware-accelerated TSI operates independently of the CPU, enabling low-power wake-on-touch functionality and eliminating the need for external touch controller ICs. The TSI module is fully supported in NXP's Kinetis SDK and works seamlessly with the MKL15Z128VLK4's 70 GPIO resources.
What are the low-power mode current specifications for MKL15Z128VLK4?
The MKL15Z128VLK4 offers nine configurable low-power modes. In VLLS0 mode with PORPO=1, typical current consumption is 0.12 µA at 25°C with full RAM and register state retention. Other key values include 1.68 µA (typ) in LLS mode, 3.75 µA (typ) in VLPS mode, and 319 µA (typ) in STOP mode - all measured at 3.0 V. Wakeup latency from VLPS to RUN is just 4 µs, enabling rapid response to external events without sacrificing energy efficiency.
Can MKL15Z128VLK4 operate across the full industrial temperature range?
Yes, the MKL15Z128VLK4 is fully specified for operation from -40°C to +105°C ambient temperature. This extended range is validated per JEDEC JESD22-A104 and JESD22-A108 standards and applies to all electrical characteristics, including flash programming, ADC accuracy, and clock stability. The device uses 90 nm TFS process technology and includes on-chip temperature monitoring - making MKL15Z128VLK4 suitable for under-hood automotive, factory automation, and outdoor infrastructure applications.
What debug interface does MKL15Z128VLK4 provide?
The MKL15Z128VLK4 provides a 2-pin Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, supporting full JTAG/SWD functionality via SWD_DIO and SWD_CLK pins. It also includes a Micro Trace Buffer (MTB) for real-time instruction trace without external probes. Debug access is enabled by default and requires no external pull-ups; the interface operates across the full voltage and temperature range and supports flash programming, breakpoint setting, and live register inspection using standard tools like Segger J-Link and NXP MCUXpresso IDE.
