Product details
Overview
MKL17Z64VDA4R 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 ultra-low-power battery-operated systems. It features 32 GPIOs, 15-channel 16-bit ADC, dual I²C up to 1 Mbit/s, two low-power UARTs, FlexIO for serial peripheral emulation, and operates from 1.71–3.6 V across –40 to 105 °C.
For engineers reviewing the MKL17Z64VDA4R datasheet, MKL17Z64VDA4R pinout, MKL17Z64VDA4R application, or MKL17Z64VDA4R equivalent, key selection criteria include its 36-pin XFBGA package, 1.68 µA stop-mode current with RTC+RAM retention, hardware CRC, SWD debug interface, and FlexIO-based protocol flexibility in space-constrained IoT sensor nodes and portable medical devices.
Technical Context
The MKL17Z64VDA4R implements a single-cycle ARMv6-M Thumb instruction set with NVIC supporting 32 interrupt vectors and 4 priority levels. Its clock system integrates HIRC48M (±0.5%), LIRC8M (±3%), and 32 kHz–32 MHz crystal support, with all peripherals configurable to select from multiple clock sources-including ERCLK32K for RTC and LPO for low-power timers.
Power management includes six static modes: VLPR (46 µA/MHz), VLPS, Stop (1.68 µA), LLS, and VLLS0–VLLS3. Wake-up is enabled via LLWU (8 external pins + 4 internal sources), AWIC (for Stop/VLPS), and NVIC (for Wait/VLPW), while security relies on flash configuration field locking and 80-bit UID.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKL27Z64VLH4 | 64-pin LQFP, 54 GPIOs, 20 ADC channels, higher pin count and I/O density | Better suited for designs requiring >32 I/Os or additional analog inputs | Select when board layout allows larger 10×10 mm LQFP and more peripheral routing headroom |
| MKE15Z64VLD4 | ARM Cortex-M0+, 48 MHz, 64 KB flash, but built on KE1x platform with enhanced CAN FD and higher temp rating (–40 to 125 °C) | Required for automotive or industrial environments exceeding 105 °C ambient | Choose when CAN FD bus integration or extended temperature operation is mandatory |
Compared with MKL17Z64VDA4R, MKL27Z64VLH4 offers greater I/O scalability in LQFP packaging but sacrifices compactness, while MKE15Z64VLD4 adds CAN FD and extended temperature support at the cost of higher BOM complexity and reduced low-power optimization focus.

FAQ
What is the operating voltage range for MKL17Z64VDA4R?
The MKL17Z64VDA4R operates from 1.71 V to 3.6 V across its full temperature range (–40 to 105 °C). This wide supply range supports direct connection to single-cell Li-ion, Li-polymer, or alkaline battery sources without intermediate regulation, and enables compatibility with both 1.8 V and 3.3 V peripheral interfaces when configured appropriately.
Does MKL17Z64VDA4R support hardware encryption or secure boot?
The MKL17Z64VDA4R does not include dedicated cryptographic accelerators (AES/SHA/RSA), but it supports secure boot through flash security bits in the FOPT register and 80-bit unique identification. The ROM bootloader enforces flash readout protection, and security can be locked via the flash configuration field - preventing unauthorized firmware extraction or modification while allowing authenticated field updates.
How many ADC channels does MKL17Z64VDA4R provide in its 36-pin XFBGA package?
The MKL17Z64VDA4R in the 36-pin XFBGA package provides 15 single-ended (SE) or 4 differential (DP) ADC input channels. This is fewer than the 20 SE/4 DP channels available in the 64-pin LQFP variant (MKL17Z64VLH4), due to pin count limitations - all 15 channels are accessible on dedicated analog input pins within the XFBGA footprint.
Can MKL17Z64VDA4R operate in stop mode while retaining RTC and RAM contents?
Yes, MKL17Z64VDA4R achieves 1.68 µA in Stop mode with both RTC and SRAM fully retained. This mode disables the core and most peripherals while keeping the RTC oscillator (ERCLK32K), low-leakage wakeup unit (LLWU), and RAM powered - enabling time-stamped wake-up events and state preservation between measurement cycles in battery-critical applications.
What debug interface does MKL17Z64VDA4R use, and is JTAG supported?
MKL17Z64VDA4R uses a 2-pin Serial Wire Debug (SWD) interface - SWD_CLK and SWD_DIO - for programming, run/halt control, and Micro Trace Buffer (MTB)-based instruction tracing. JTAG is not supported; SWD provides equivalent functionality with reduced pin count and lower PCB routing overhead, aligning with the device's emphasis on compact, low-cost design.
