Product details
Overview
MKL15Z64VFM4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in 32-pin QFN package, featuring 64 KB flash, 8 KB SRAM, 16-bit SAR ADC, 12-bit DAC, and ultra-low-power operation down to 0.31 µA in VLLS0 mode. It integrates two UARTs, two I²C, two SPI, TSI touch interface, and six-channel TPM for embedded control in battery-powered industrial sensors and portable HMI devices.
For engineers reviewing the MKL15Z64VFM4 datasheet, MKL15Z64VFM4 pinout, MKL15Z64VFM4 application, or MKL15Z64VFM4 equivalent, this page delivers verified electrical specs, low-power mode timing, peripheral adder currents, GPIO count (28), and QFN-32 package mapping - all confirmed from KL15P80M48SF0 Rev 5 (08/2014) and official package drawing 98ASA00473D1.
Technical Context
The MKL15Z64VFM4 implements a single-core ARM Cortex-M0+ with 90 nm TFS process, clock gating, and zero-wait-state flash controller. Its MCG supports FEI, FBE, BLPI, and BLPE modes, enabling dynamic switching between 48 MHz run and 4 MHz VLPR modes with sub-5 µs wakeup from VLPS/STOP.
System-level power management includes nine low-power modes (VLLS0–VLLS3, LLS, VLPS, STOP, WAIT, RUN), COP watchdog, low-leakage wakeup unit, and hardware bit manipulation engine (BME). Analog subsystem comprises 16-bit ADC (up to 1 MSPS), 12-bit DAC, and comparator with integrated 6-bit DAC reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKL15Z64VFT4 | 48-pin QFN, 40 GPIO, identical core/peripherals - adds 12 more I/O pins and larger package footprint. | Required where board layout needs >28 GPIO or additional analog inputs (e.g., multi-sensor fusion). | Select MKL15Z64VFT4 only if extra I/O or routing flexibility justifies larger 7×7 mm footprint and higher BOM cost. |
| STM32L053R8T6 | ARM Cortex-M0+, 32 KB flash, 8 KB SRAM, 48-pin LQFP - lower memory, different peripheral set (no TSI, no 12-bit DAC), comparable 0.33 µA stop mode. | Suitable for cost-sensitive designs where touch interface is unnecessary and flash size suffices. | Choose STM32L053R8T6 when migrating legacy ST designs or when TSI/12-bit DAC are not required - verify UART/I²C timing compatibility. |
Compared with MKL15Z64VFM4, MKL15Z64VFT4 offers expanded I/O in a larger QFN, while STM32L053R8T6 trades TSI and 12-bit DAC for lower cost and established ST ecosystem - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum operating frequency of the MKL15Z64VFM4 core?
The MKL15Z64VFM4 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 voltage. The MKL15Z64VFM4 maintains deterministic timing at this speed with zero-wait-state flash execution.
Does the MKL15Z64VFM4 support hardware touch sensing?
Yes, the MKL15Z64VFM4 includes a dedicated Touch Sensing Interface (TSI) module supporting up to eight capacitive sensing channels. It operates independently of the CPU in low-power modes and provides hardware-accelerated charge-transfer measurement, enabling robust touch-button or slider implementation with minimal firmware overhead and immunity to EMI in noisy environments.
What are the lowest power consumption modes supported by the MKL15Z64VFM4?
The MKL15Z64VFM4 supports nine low-power modes, with VLLS0 delivering the lowest active current: 0.31 µA (typ) at 25°C and 3.0 V, retaining full SRAM and register state. VLLS1 draws 0.58 µA (typ), and VLLS3 draws 1.22 µA (typ). All three offer sub-100 µs wakeup times, making them ideal for wake-on-event sensor endpoints where battery life exceeds five years.
How many GPIO pins does the MKL15Z64VFM4 provide in its 32-pin QFN package?
The MKL15Z64VFM4 in the 32-pin QFN (FM) package provides 28 general-purpose I/O pins, as confirmed in the Freescale ordering information table. These include multiplexed functions such as UART, I²C, SPI, ADC inputs, and TSI channels - all accessible through configurable pin-control registers without requiring external level shifters or buffers.
Is the MKL15Z64VFM4 pin-compatible with other Kinetis KL15 variants?
No, the MKL15Z64VFM4 is not pin-compatible with other KL15 package variants (e.g., VFT4, VLH4, VLK4) due to differing pin counts and physical layouts. The 32-pin QFN (FM) has a unique 5×5 mm footprint and signal mapping distinct from the 48-pin QFN (FT), 64-pin LQFP (LH), and 80-pin LQFP (LK) packages - PCB layout must be designed specifically for MKL15Z64VFM4.
