Product details
Overview
MKL17Z64VFM4 from NXP (formerly Freescale) is a 32-bit ARM® Cortex®-M0+ microcontroller optimized for ultra-low-power battery-operated applications, featuring 64 KB flash, 16 KB SRAM, and 32-pin QFN (5×5 mm, 0.5 mm pitch) packaging. It delivers 48 MHz core performance with down to 46 µA/MHz in very low power run mode and 1.68 µA in stop mode (RAM + RTC retained), supporting embedded sensing and wireless edge-node control.
For engineers reviewing the MKL17Z64VFM4 datasheet, MKL17Z64VFM4 pinout, MKL17Z64VFM4 application, or MKL17Z64VFM4 equivalent, key selection criteria include its FlexIO peripheral for custom serial interface emulation, hardware CRC module for firmware integrity, integrated 16-bit ADC with up to 11 single-ended/2 differential channels, and dual low-power UARTs enabling always-on communication in sleep states.
Technical Context
The MKL17Z64VFM4 implements an ARM Cortex-M0+ core with Thumb-2 instruction set support, NVIC with 32 interrupt vectors and 4 priority levels, and a crossbar switch enabling concurrent bus master access to peripherals. Its clock system integrates HIRC48M (±0.5% accuracy), LIRC8M (±3%), and 32–40 kHz/3–32 MHz crystal oscillator support - all configurable via MCG-Lite.
Power management includes six static low-power modes (Run, VLPR, Wait, VLPW, Stop, VLPS, LLS, VLLS), with AWIC and LLWU controllers enabling wake-up from Stop/VLPS and LLS/VLLS modes respectively. Peripherals are selectively clock-gated per mode: ADC, CMP, RTC, and LPUART remain active in VLPS; only LLWU, LPTMR, and RTC operate in VLLS3 with RAM retention.

FAQ
What is the maximum operating frequency of the MKL17Z64VFM4?
The MKL17Z64VFM4 features an ARM Cortex-M0+ core with a maximum operating frequency of 48 MHz, enabled by its high-accuracy internal 48 MHz HIRC oscillator (±0.5% tolerance). This frequency is fully supported across all operating voltage ranges (1.71–3.6 V) and temperature grades (–40 to +105 °C), as verified in the KL17P64M48SF2 datasheet Section 5.2.1.
Does the MKL17Z64VFM4 include a hardware bootloader?
Yes, the MKL17Z64VFM4 integrates a 16 KB ROM bootloader that supports firmware updates via UART, I²C, and SPI interfaces without requiring external programming hardware. This factory-programmed bootloader is accessible after reset when boot configuration pins are asserted, and is documented in the KL17P64M48SF2 Reference Manual Chapter 2.1.4 and Section 2.1.5.
How many ADC channels does the MKL17Z64VFM4 support in its 32-pin QFN package?
In the MKL17Z64VFM4 32-pin QFN package, the device supports 11 single-ended or 2 differential ADC input channels, as confirmed in Table 1 (Ordering Information) and Section 2.2.4 of the KL17P64M48SF2 datasheet. Channel mapping is constrained by pin multiplexing - not all 20 total channels available in larger packages are routed to this 32-pin variant.
What low-power modes are available on the MKL17Z64VFM4, and what is the lowest current consumption?
The MKL17Z64VFM4 supports six low-power modes including VLPR, VLPW, Stop, VLPS, LLS, and VLLS variants. Its lowest measured current is 1.68 µA in Stop mode with RAM and RTC retained, and 500 nA in VLLS3 mode with RAM retained - both specified at 3.0 V and 25 °C per Section 5.2.2 of the KL17P64M48SF2 datasheet Rev. 5.
Is the MKL17Z64VFM4 pin-compatible with other Kinetis KL17 variants?
No - the MKL17Z64VFM4 (32-pin QFN) is not pin-compatible with other KL17 packages such as the 64-pin LQFP (MKL17Z64VLH4) or 36-pin XFBGA (MKL17Z64VDA4), due to differing pin counts, signal assignments, and power/ground distribution. Pin compatibility is only guaranteed within the same package type and pin count, as detailed in Section 4.4 of the KL17P64M48SF2 datasheet.
