Product details
Overview
MKL13Z64VLH4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ microcontroller with 64 KB flash, 8 KB SRAM, and 8 KB ROM bootloader, designed for ultra-low-power battery-operated systems. It delivers 60 µA/MHz active power consumption, 1.83 µA deep-sleep current with RTC + RAM retention, and supports 20-channel 16-bit ADC with internal voltage reference - deployed in portable medical sensors and smart utility meters.
For engineers reviewing the MKL13Z64VLH4 datasheet, MKL13Z64VLH4 pinout, MKL13Z64VLH4 application, or MKL13Z64VLH4 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C industrial temperature range, integrated FlexIO for custom serial peripheral emulation, hardware CRC engine, and dual low-power UARTs enabling always-on communication in energy-constrained edge nodes.
Technical Context
The MKL13Z64VLH4 implements an ARM Cortex-M0+ core with Micro Trace Buffer and Bit Manipulation Engine, paired with a configurable MCG-Lite clock system supporting HIRC (48 MHz ±0.5%), LIRC (8/2 MHz), and external crystal options (32 kHz–32 MHz). Its power architecture includes six static low-power modes - VLLS0 (95 nA), VLLS1 (1.31 µA), VLLS3 (1.83 µA), LLS, VLPS, and STOP - each with selective peripheral gating and wake-up source control.
Peripherals are segmented across dedicated modules: two I²C interfaces (up to 1 Mbit/s), two SPI controllers (24 Mbit/s), one UART (1.5 Mbit/s ISO7816), two low-power UARTs, FlexIO for runtime-emulated protocols, 12-bit DAC, high-speed analog comparator with 6-bit DAC reference, and a 6-channel Timer/PWM plus two 2-channel Timer/PWM units - all accessible under sub-2 µA retention states.

FAQ
What is the maximum operating frequency and core type of the MKL13Z64VLH4?
The MKL13Z64VLH4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achieved using the internal high-accuracy reference clock (HIRC) trimmed to ±0.5% over temperature and voltage. The MKL13Z64VLH4 does not support external PLL multiplication; its maximum system clock is strictly limited to the HIRC output or externally sourced crystal frequencies.
Does the MKL13Z64VLH4 support USB or Ethernet connectivity?
No, the MKL13Z64VLH4 does not include native USB or Ethernet MAC/PHY peripherals. Its communication interfaces are limited to UART, low-power UART, I²C, SPI, and FlexIO-emulated protocols. For USB connectivity, external bridge ICs (e.g., CP2102N) must be used; Ethernet requires discrete PHY and MAC controllers or external SoC co-processing.
What is the purpose of the 8 KB ROM bootloader in the MKL13Z64VLH4?
The 8 KB ROM bootloader in the MKL13Z64VLH4 provides factory-programmed firmware that enables in-system programming via UART or USB HID without requiring JTAG/SWD debug hardware. It supports secure flash updates, CRC validation of new images, and fallback to known-good firmware - critical for remote, battery-powered deployments where physical access is impractical.
Can the MKL13Z64VLH4 operate from a single 1.8 V supply?
Yes, the MKL13Z64VLH4 supports a minimum supply voltage of 1.71 V, making it fully operational at 1.8 V. At this voltage, the maximum achievable core frequency is reduced to approximately 24 MHz (per datasheet Table 9), and analog performance (e.g., ADC ENOB, DAC linearity) remains within specification across the full –40°C to +105°C range.
How many ADC channels does the MKL13Z64VLH4 support, and what is their resolution?
The MKL13Z64VLH4 integrates a single 16-bit successive-approximation ADC module with up to 20 input channels - configurable as 20 single-ended or 4 differential inputs. Conversion rates reach 818 ksps, and the module includes a high-accuracy internal 1.2 V voltage reference, eliminating dependency on external precision references for most sensor applications.
