Product details
Overview
MKL16Z64VLH4R from NXP Semiconductors is a 48 MHz ARM® Cortex®-M0+ based microcontroller in 64-pin LQFP package, featuring 64 KB flash, 8 KB SRAM, and up to 54 GPIOs. It delivers ultra-low-power operation down to 0.4 µA in VLLS0 mode with full state retention and 4.5 µs wakeup, supporting battery-powered industrial sensors and portable HMI devices.
For engineers reviewing the MKL16Z64VLH4R datasheet, MKL16Z64VLH4R pinout, MKL16Z64VLH4R application, or MKL16Z64VLH4R equivalent, key selection criteria include its 4-channel DMA, dual UART + I²C + SPI interfaces, 16-bit SAR ADC, and nine low-power modes optimized for energy-constrained embedded control.
Technical Context
The MKL16Z64VLH4R implements a tightly integrated low-power architecture with clock gating, multiple voltage domains (VDD/VDDA), and dynamic power mode transitions. Its MCG clock system supports FEI, FBE, BLPI, and PEE modes, enabling flexible trade-offs between performance (48 MHz) and ultra-low-power operation (4 MHz core in VLPR).
Peripheral integration includes a Bit Manipulation Engine for efficient register access, SWD debug interface with Micro Trace Buffer, and hardware TSI for capacitive touch sensing. The analog subsystem combines a 16-bit SAR ADC, 12-bit DAC, and comparator with internal 6-bit DAC reference - all operable in low-leakage stop modes.
