Product details
Overview
MKL27Z64VLH4R from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ microcontroller with 64 KB flash, 16 KB SRAM, and USB Full-Speed 2.0 device controller supporting crystal-less operation - designed for battery-powered, cost-sensitive edge nodes requiring low-power connectivity and integrated analog peripherals including 16-bit ADC (17-channel, 818 ksps), FlexIO, and hardware CRC. It operates from 1.71–3.6 V across –40 to 105 °C in 64-pin LQFP.
For engineers reviewing the MKL27Z64VLH4R datasheet, MKL27Z64VLH4R pinout, MKL27Z64VLH4R application, or MKL27Z64VLH4R equivalent, key selection criteria include USB crystal-less capability, sub-2 µA stop-mode current (RAM + RTC retained), FlexIO-based peripheral emulation, 46 µA/MHz run-mode efficiency, and integrated ROM bootloader supporting UART/I2C/SPI/USB firmware updates.
Technical Context
The MKL27Z64VLH4R implements a tightly coupled ARM Cortex-M0+ core with NVIC, AWIC, and LLWU controllers enabling deterministic wake-up from six low-power modes - including Stop (1.68 µA), VLPS, and VLLS3 - while retaining RAM and RTC. Its clock system integrates HIRC48M (±0.5% accuracy for USB), LIRC8M, and 32 kHz–32 MHz crystal support, with MCG-Lite providing flexible source selection per operational mode.
Peripherals are partitioned across bus domains: Platform clock (max 48 MHz) drives core and GPIO; System clock (max 48 MHz) feeds USB and SPI1; Bus clock (max 24 MHz) serves ADC, I²C, TPM, and DMA. FlexIO operates independently with its own clock domain, enabling runtime reconfiguration of serial interfaces without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M0+, 48 MHz max - delivers deterministic real-time control with Thumb-2 instruction set and 15-cycle interrupt latency. |
| Memory | 64 KB flash / 16 KB SRAM / 16 KB ROM bootloader - enables field-upgradable firmware via USB/I2C/SPI without external host. |

MKL27Z64VLH4R provides 51 GPIO pins across five ports (PTA–PTE), with up to 6 supporting high-drive (20 mA) output and all configurable for interrupt-on-change, pull-up/down, and slew rate control. Pin multiplexing is documented in Section 4.1 of the KL27P64M48SF2 datasheet, including shared functions with ADC, UART, and FlexIO.
Can MKL27Z64VLH4R perform firmware updates over USB without external programming hardware?
Yes, MKL27Z64VLH4R includes a factory-programmed 16 KB ROM bootloader that supports USB CDC-class firmware updates out-of-box. The bootloader is activated via BOOTCFG0 pin configuration and enables secure, field-deployable firmware upgrades without JTAG/SWD debug tools - detailed in Section 2.1.4 and Application Note AN4763.
What analog peripherals are integrated into MKL27Z64VLH4R?
MKL27Z64VLH4R integrates a 16-bit SAR ADC with up to 17 channels and 818 ksps sampling rate, a 6-bit DAC for programmable comparator reference, and a high-accuracy 1.2 V internal voltage reference.
