Product details
Overview
MKL17Z256VMP4R from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ microcontroller with 256 KB flash, 32 KB SRAM, and 16 KB ROM bootloader, designed for ultra-low-power battery-operated systems. It delivers 54 µA/MHz in very low power run mode, 1.96 µA in VLLS3 deep-sleep mode (RAM + RTC retained), and supports up to 54 GPIOs in a 64-pin MAPBGA package - ideal for portable medical sensors and smart metering endpoints.
For engineers reviewing the MKL17Z256VMP4R datasheet, MKL17Z256VMP4R pinout, MKL17Z256VMP4R application, or MKL17Z256VMP4R equivalent, key selection criteria include its dual internal clock accuracy (0.5% at 48 MHz, 3% at 8/2 MHz), FlexIO-based peripheral emulation capability, 16-channel 12-bit ADC with internal Vref, and verified operation across –40 to 105 °C in MAPBGA packaging.
Technical Context
The MKL17Z256VMP4R implements an ARM Cortex-M0+ core with Micro Trace Buffer and Bit Manipulation Engine, paired with a flexible MCG-Lite clock system supporting HIRC (48 MHz), LIRC (2/8 MHz), and external crystal sources (32 kHz–32 MHz). Its low-power architecture includes six static power modes - VLLS0 through RUN - with sub-µA retention states enabled by dedicated low-leakage wakeup logic and configurable RTC backup.
Peripherals are organized around a 4-channel asynchronous DMA controller and dual clock domains: high-speed (up to 48 MHz) for CPU/flash and low-frequency (1 kHz–32 kHz) for RTC/LPTMR. The FlexIO module provides programmable serial interface emulation (UART/I²C/SPI/I²S/PWM), while analog subsystems integrate a 12-bit DAC, high-speed comparator with 6-bit reference DAC, and 16-channel ADC with built-in 1.2 V reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| KL27Z256VLH4 | Same Cortex-M0+ core, 48 MHz, but adds USB OTG PHY and higher ADC resolution (16-bit); larger 64-LQFP package. | Better suited for USB-connected diagnostics tools; lacks MAPBGA option and has higher active current (7.39 mA vs 6.45 mA at 48 MHz). | Select when USB device functionality is mandatory and board space permits LQFP; avoid if MAPBGA footprint or lowest deep-sleep current is required. |
| STM32L072KBU6 | ARM Cortex-M0+, 32 MHz, 128 KB flash, 20 KB SRAM; 32-QFN only; lower deep-sleep (0.33 µA) but no FlexIO or ROM bootloader. | Targeted at simpler sensor nodes without protocol emulation needs; requires external bootloader implementation. | Choose for ultra-low-quiescent designs where peripheral flexibility is secondary to absolute minimum sleep current and cost. |
Compared with KL27Z256VLH4 and STM32L072KBU6, MKL17Z256VMP4R uniquely balances MAPBGA density, FlexIO-driven hardware reconfigurability, and sub-2 µA deep-sleep - making it optimal for compact, field-upgradable, multi-protocol edge nodes requiring long battery life.

FAQ
What is the maximum operating temperature range for MKL17Z256VMP4R?
MKL17Z256VMP4R is rated for –40 to 105 °C operation, validated for MAPBGA packaging per NXP's datasheet Rev. 7 (Oct 2023). This extended range supports deployment in automotive cabin environments and industrial enclosures without forced cooling, unlike commercial-grade variants limited to 85 °C.
Does MKL17Z256VMP4R include a factory-programmed bootloader?
Yes, MKL17Z256VMP4R integrates 16 KB of ROM containing a production-ready bootloader supporting UART and I²C firmware updates. This eliminates the need for external programming hardware during field upgrades and enables secure over-the-air patching in certified medical or utility applications.
How many ADC channels does MKL17Z256VMP4R support, and what is their resolution?
MKL17Z256VMP4R features a single 16-channel, 12-bit successive-approximation ADC with integrated high-accuracy 1.2 V internal voltage reference. It supports both single-ended (up to 16 channels) and differential (up to 4 pairs) configurations, enabling precision ratiometric measurements in battery-powered sensor systems.
What debug interface does MKL17Z256VMP4R use, and how many pins are required?
MKL17Z256VMP4R uses a two-pin Serial Wire Debug (SWD) interface - SWD_CLK and SWD_DIO - supporting full programming, real-time tracing via Micro Trace Buffer, and non-intrusive variable inspection. This reduces debug header footprint by 50% versus traditional JTAG, preserving PCB space in miniaturized designs.
Is MKL17Z256VMP4R pin-compatible with other KL17 family members in the same package?
Yes, MKL17Z256VMP4R shares identical 64-pin MAPBGA pinout and signal mapping with MKL17Z128VMP4 and MKL17Z256VMP4 (non-R suffix), enabling flash-size scalability without PCB redesign. However, the 'R' suffix denotes tape-and-reel packaging - electrical and mechanical compatibility remains unchanged.
