Product details
Overview
MKL17Z64VLH4R from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ microcontroller with 64 KB flash, 16 KB SRAM, and 16 KB ROM bootloader, designed for battery-powered IoT sensors and low-power industrial control nodes requiring integrated FlexIO, hardware CRC, and sub-2 µA stop-mode operation. It features 54 GPIOs, 20-channel 16-bit ADC, and dual low-power UARTs.
For engineers reviewing the MKL17Z64VLH4R datasheet, MKL17Z64VLH4R pinout, MKL17Z64VLH4R application, or MKL17Z64VLH4R equivalent, key selection criteria include its 64-pin LQFP package, 1.71–3.6 V operating range, –40 to 105 °C temperature grade, and verified support for UART/I2C/SPI bootloading via embedded ROM.
Technical Context
The MKL17Z64VLH4R implements an ARM Cortex-M0+ core with NVIC supporting 32 interrupt vectors and 4 priority levels, coupled with a multiplexed crossbar switch enabling concurrent bus master access. Its MCG-Lite clock system delivers 48 MHz HIRC with ±0.5% accuracy and retains 1 kHz LPO across all low-power modes except VLLS0.
Power management includes six static modes-down to 1.68 µA in Stop mode with RAM + RTC retained-and wake-up capability via LLWU (8 external pins + 4 internal sources), AWIC, and NVIC. Peripherals are clock-gated per module, with FlexIO enabling runtime emulation of UART, SPI, I2C, PWM, and I2S on configurable pins.

FAQ
What is the maximum operating frequency and voltage range of the MKL17Z64VLH4R?
The MKL17Z64VLH4R operates at up to 48 MHz with a supply voltage range of 1.71 V to 3.6 V. This allows direct integration with single-cell Li-ion, Li-Po, or alkaline battery sources without intermediate regulation, while maintaining full peripheral functionality across the entire voltage window.
Does the MKL17Z64VLH4R support in-system programming via its ROM bootloader?
Yes, the MKL17Z64VLH4R includes 16 KB of ROM containing a factory-programmed bootloader that supports firmware updates over UART, I²C, or SPI interfaces. This eliminates dependency on external debug probes during production programming or field upgrades, enhancing manufacturing scalability and serviceability.
How many GPIO pins does the MKL17Z64VLH4R provide, and what advanced I/O features are supported?
The MKL17Z64VLH4R provides 54 general-purpose I/O pins across five ports (A–E), each supporting programmable pull-up/down resistors, digital filters, edge-triggered interrupts, and high-drive capability. All GPIOs are multiplexed with peripheral functions including ADC, FlexIO, and low-power UARTs.
What low-power modes are available on the MKL17Z64VLH4R, and what is the lowest achievable current draw?
The MKL17Z64VLH4R supports six low-power modes, including Stop mode with RAM + RTC retention at 1.68 µA. In Very Low Leakage Stop (VLLS3), it achieves sub-1 µA operation while retaining SRAM and system registers - enabling decade-long operation on primary lithium batteries in metering and environmental monitoring.
Is the MKL17Z64VLH4R pin-compatible with other members of the KL17 family?
Yes, the MKL17Z64VLH4R shares identical 64-pin LQFP packaging and pinout with MKL17Z32VLH4 and MKL17Z64VMP4 (MAPBGA), enabling hardware reuse across memory variants. However, XFBGA and QFN packages have distinct pin mappings and require board redesign for migration.
