NXP Semiconductors MKL24Z64VLK4

Overview

MKL24Z64VLK4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in 80-pin LQFP package, featuring 64 KB flash, 8 KB SRAM, USB 2.0 On-The-Go with on-chip transceiver, 12-bit SAR ADC, and ultra-low-power operation down to 0.31 µA in VLLS0 mode. It targets battery-powered industrial sensors and portable HMI devices requiring full state retention and sub-5 µs wake-up.

For engineers reviewing the MKL24Z64VLK4 datasheet, MKL24Z64VLK4 pinout, MKL24Z64VLK4 application, or MKL24Z64VLK4 equivalent, this page delivers verified electrical specs, validated low-power mode behavior, confirmed USB transceiver integration, exact GPIO count (66), and real-world timing performance across nine power modes - all specific to the MKL24Z64VLK4 variant.

Technical Context

The MKL24Z64VLK4 implements a single-core ARM Cortex-M0+ processor with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB), executing from zero-wait-state flash. Its clock system integrates a multi-mode MCG with internal 4 MHz IRC, 32 kHz LPO, and external crystal support up to 16 MHz for precise USB timing.

System-level power management includes nine configurable low-power modes (VLLS0–VLLS3, LLS, VLPS, STOP, WAIT, RUN), with hardware-controlled entry/exit and peripheral-specific current adders documented per mode. The USB module operates at full-speed (12 Mbps) or low-speed (1.5 Mbps) using its integrated 5 V-to-3.3 V regulator and differential transceiver - no external PHY required.

FAQ

What is the maximum operating frequency of the MKL24Z64VLK4 core?

The MKL24Z64VLK4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is achievable with the MCG in PEE mode using an external crystal or internal FLL, and supports zero-wait-state execution from flash memory. At 48 MHz, the MKL24Z64VLK4 delivers 30.5 CoreMark/MHz performance under Keil-optimized conditions, making it suitable for real-time control tasks in industrial and medical applications.

Does the MKL24Z64VLK4 include an integrated USB transceiver?

Yes, the MKL24Z64VLK4 includes a full-/low-speed USB 2.0 On-The-Go controller with an integrated differential transceiver and a built-in 5 V-to-3.3 V regulator. This eliminates the need for external USB PHY components and level shifters. The transceiver complies with USB specification timing requirements when paired with a 3–32 MHz crystal, and supports both device and host roles in appropriate software configurations.

How many GPIO pins does the MKL24Z64VLK4 provide, and what drive strengths are supported?

The MKL24Z64VLK4 provides 66 general-purpose I/O pins across five port banks (PTA–PTE). Four pins - PTB0, PTB1, PTD6, and PTD7 - support high-drive mode (18 mA sink/source at 3.0 V), configurable via the DSE bit in their PCR registers. All GPIOs support programmable pull-up/pull-down (20–50 kΩ), slew rate control, and interrupt-on-change functionality, enabling direct LED driving and robust noise immunity in industrial environments.

What is the lowest power consumption mode available on the MKL24Z64VLK4, and what features remain active?

The MKL24Z64VLK4 achieves its lowest power state in Very-Low-Leakage Stop Mode 0 (VLLS0), consuming just 0.31 µA at 25°C with full 8 KB SRAM retention and 4 µs wake-up time. In this mode, the core, system clocks, and most peripherals are disabled, but the low-leakage wakeup unit (LLWU), RTC, and selected I/O pins retain functionality to trigger wake-up events. VLLS0 is ideal for long-duration sleep in battery-powered sensor nodes where infrequent wake-up is required.

Is the MKL24Z64VLK4 compatible with development tools like Kinetis Design Studio or MCUXpresso IDE?

Yes, the MKL24Z64VLK4 is fully supported by NXP's MCUXpresso IDE (successor to Kinetis Design Studio), including device-specific SDKs, CMSIS-compliant drivers, and example projects for USB, ADC, low-power modes, and communication interfaces. It also works with standard ARM Cortex-M debug probes (e.g., LPC-Link2, Segger J-Link) via SWD interface. NXP provides validated BSPs and peripheral initialization code, ensuring rapid bring-up for production firmware development.
