For engineers reviewing the MKL25Z64VLH4 datasheet, MKL25Z64VLH4 pinout, MKL25Z64VLH4 application, or MKL25Z64VLH4 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases for USB-connected edge devices, and confirmed alternative parts with documented functional and packaging differences.

Technical Context

The MKL25Z64VLH4 implements an ARM Cortex-M0+ core with Bit Manipulation Engine (BME) and Micro Trace Buffer (MTB), executing from zero-wait-state flash memory. Its clock system integrates a multi-purpose oscillator supporting internal 4 MHz/32 kHz IRC and external crystal inputs (32 kHz–32 MHz), with configurable MCG modes including FEI, FBE, PEE, and BLPI for dynamic power/performance scaling.

System-level low-power architecture includes nine distinct power modes (RUN, VLPR, STOP, VLPS, LLS, VLLS0–3), each with deterministic wakeup latency and peripheral retention options. The USB controller operates at full/low speed with integrated 5 V-to-3.3 V regulator and supports device/host/OTG roles without external PHY components.

FAQ

What is the maximum operating frequency of the MKL25Z64VLH4 core?

The MKL25Z64VLH4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achievable using the Phase-Locked Loop (PLL) with an external crystal or internal reference clock, and is supported across the full voltage range (1.71–3.6 V) and temperature range (–40°C to +105°C). The MKL25Z64VLH4 maintains zero-wait-state flash execution at this speed, ensuring deterministic real-time performance.

Does the MKL25Z64VLH4 include an integrated USB transceiver?

Yes, the MKL25Z64VLH4 integrates a full-/low-speed USB 2.0 On-The-Go controller with an on-chip transceiver and a 5 V-to-3.3 V regulator. This eliminates the need for external USB PHY components or level-shifting circuitry. The USB_DP and USB_DM pins connect directly to the USB connector, and the internal regulator allows operation from a standard 5 V USB bus while powering the MCU's 3.3 V domain.

How many GPIO pins does the MKL25Z64VLH4 provide in its 64-pin LQFP package?

The MKL25Z64VLH4 in the 64-pin LQFP package provides 50 general-purpose input/output (GPIO) pins. These are distributed across PORTA, PORTB, PORTC, and PORTD, with multiple alternate functions including UART, SPI, I²C, TSI, and ADC channels. All 50 pins support interrupt capability, DMA request generation, and configurable internal pull-up/pull-down resistors (20–50 kΩ).

What is the lowest power consumption mode available on the MKL25Z64VLH4?

The MKL25Z64VLH4 supports Very Low-Leakage Stop Mode 0 (VLLS0) with typical current consumption of 0.31 µA at 25°C and 3.0 V, with full RAM and register retention. In this mode, the device retains all state while disabling clocks to non-essential modules and can wake in as little as 4 µs via GPIO, RTC alarm, or low-power timer. VLLS0 is ideal for long-duration sleep in battery-powered applications requiring instant responsiveness.

Is the MKL25Z64VLH4 compatible with the Kinetis SDK and MCUXpresso IDE?

Yes, the MKL25Z64VLH4 is fully supported by NXP's MCUXpresso IDE and Kinetis SDK (KSDK) v2.x. MCUXpresso provides integrated debugging, configuration tools (including pinmux and clock tree setup), and example projects for USB CDC, HID, ADC, and low-power modes. The MKL25Z64VLH4 is also validated with FreeRTOS and uTasker, enabling rapid development of production-ready firmware.
