Product details
Overview
MKL27Z256VMP4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ microcontroller with 256 KB flash, 32 KB SRAM, and USB Full-Speed 2.0 device controller supporting crystal-less operation. It integrates a 16-bit 818 ksps ADC, 12-bit DAC, FlexIO for serial peripheral emulation, and achieves 1.96 µA in VLLS3 deep-sleep mode with RTC and RAM retention - optimized for battery-powered USB peripherals like smart sensors and portable medical devices.
For engineers reviewing the MKL27Z256VMP4 datasheet, MKL27Z256VMP4 pinout, MKL27Z256VMP4 application, or MKL27Z256VMP4 equivalent, key selection criteria include its 64-pin MAPBGA package, 50 GPIOs with 6 high-drive pads, 16-channel ADC (SE/DP), internal 48 MHz ±0.5% reference clock, and support for six low-power modes down to 54 µA/MHz in very-low-power run mode.
Technical Context
The MKL27Z256VMP4 implements an ARM Cortex-M0+ core with Micro Trace Buffer and Bit Manipulation Engine, paired with a flexible clock system featuring factory-trimmed 48 MHz HIRC (±0.5%), 8/2 MHz IRC, and 32 kHz–32 MHz crystal oscillator support. Its MCG-Lite clock generator enables seamless transitions between run, wait, stop, and multiple very-low-leakage stop (VLLS) modes.
Peripherals include one USB FS 2.0 controller with integrated transceiver and voltage regulator, two low-power UARTs active in VLPS/VLLS modes, dual I²C (up to 1 Mbit/s), dual SPI (up to 24 Mbit/s), I²S audio interface, and FlexIO capable of emulating UART, IrDA, SPI, I²C, I²S, or PWM - all accessible via multiplexed 50 GPIO pins in the 64-ball MAPBGA package.

FAQ
What is the maximum operating frequency of the MKL27Z256VMP4?
The MKL27Z256VMP4 operates at up to 48 MHz using its factory-trimmed internal high-speed reference clock (HIRC), which maintains ±0.5% accuracy across voltage and temperature. This frequency is fully supported for core, bus, and flash execution - enabling real-time response in USB and sensor applications without external clock sources.
Does the MKL27Z256VMP4 support crystal-less USB operation?
Yes, the MKL27Z256VMP4 integrates a USB Full-Speed 2.0 device controller with an internal 48 MHz clock trimmed to ±0.25% over voltage and temperature - meeting USB specification timing requirements without an external 12 MHz crystal. This eliminates two passive components and simplifies PCB layout for compact USB peripherals.
What low-power modes are available on the MKL27Z256VMP4?
The MKL27Z256VMP4 supports six static low-power modes: RUN, VLPR, WAIT, STOP, LLS, and three VLLS variants (VLLS0–VLLS3). In VLLS3 mode, it draws just 1.96 µA while retaining RAM and RTC - ideal for wake-on-external-interrupt applications such as environmental sensors or security peripherals.
How many ADC channels does the MKL27Z256VMP4 support?
The MKL27Z256VMP4 features a 16-bit SAR ADC with up to 16 input channels in single-ended configuration (7 SE / 0 DP for this MAPBGA variant). It includes an internal 1.2 V reference, programmable gain amplifier, and hardware averaging - delivering high-precision analog measurements for battery voltage monitoring or sensor signal conditioning.
What debug interface does the MKL27Z256VMP4 provide?
The MKL27Z256VMP4 uses a two-pin Serial Wire Debug (SWD) interface (SWD_CLK and SWD_DIO) for programming and real-time debugging. This minimal-pin-count interface supports full JTAG-equivalent functionality - including breakpoints, watchpoints, and memory inspection - while freeing all other GPIOs for application use.
