NXP Semiconductors MKE16F256VLH16

Overview

MKE16F256VLH16 from NXP Semiconductors is an ARM® Cortex®-M4 based microcontroller operating at up to 168 MHz with single-precision FPU, 256 KB ECC-protected flash, 32 KB ECC SRAM, and integrated FlexNVM (64 KB data flash + 4 KB emulated EEPROM). It delivers deterministic real-time control for motor drives and industrial sensing with low-power LPUART/LPSPI/LPI2C interfaces active in Stop mode.

For engineers reviewing the MKE16F256VLH16 datasheet, MKE16F256VLH16 pinout, MKE16F256VLH16 application, or MKE16F256VLH16 equivalent, key selection criteria include its 64-pin LQFP package, 58 GPIOs (8 high-drive), triple 12-bit ADCs (1 MSPS), FlexCAN v2.0 support, and hardware CRC/ECC for functional safety compliance.

Technical Context

The MKE16F256VLH16 implements a full ARMv7-M architecture with Thumb®-2 ISA, DSP extensions, and configurable NVIC supporting 92 IRQ sources. Its SCG clock system integrates FIRC (48 MHz ±1%), SIRC (8/2 MHz ±3%), OSC32 (32 kHz), and PLL for precise timing across run/stop modes.

Power management uses PMC with seven operational states (HSRun, Run, VLPR, Wait, VLPW, Stop, VLPS), enabling sub-μA wake-up from Stop via AWIC-triggered peripherals including LPTMR, RTC, CMP, and ADC-all operating on SIRC or OSC32 clocks without core restart.

FAQ

What is the maximum operating frequency of the MKE16F256VLH16?

The MKE16F256VLH16 operates at up to 168 MHz using its ARM Cortex-M4 core with integrated single-precision floating-point unit (FPU). This frequency is achieved via the SCG clock generator with PLL configuration, and performance is validated across the full –40°C to +105°C temperature range and 2.7–5.5 V supply voltage.

Does the MKE16F256VLH16 support hardware error correction for memory?

Yes, the MKE16F256VLH16 implements ECC (Error-Correcting Code) on both its 256 KB program flash and 32 KB SRAM. This provides automatic single-bit error correction and multi-bit error detection-critical for functional safety applications such as industrial control and automotive body electronics where memory integrity must be guaranteed.

How many analog-to-digital converters does the MKE16F256VLH16 include, and what are their capabilities?

The MKE16F256VLH16 integrates three independent 12-bit SAR ADC modules, each supporting up to 16 single-ended analog inputs and sampling at up to 1 MSPS. They feature hardware triggers from FTM, LPTMR, RTC, or comparators, self-calibration, temperature sensor input, and operation in Stop/VLPS modes using internal clock sources-enabling precise, low-power sensor acquisition.

Can the MKE16F256VLH16 operate in low-power modes while maintaining communication functionality?

Yes, the MKE16F256VLH16 supports full LPUART, LPSPI, and LPI2C operation in Stop and VLPS modes using the SIRC (8/2 MHz) or OSC32 (32.768 kHz) clock sources. This allows continuous serial communication-including firmware updates and sensor telemetry-without waking the Cortex-M4 core, significantly reducing system-level power consumption.

What debug interface does the MKE16F256VLH16 provide, and is it compatible with standard tools?

The MKE16F256VLH16 features a Serial Wire Debug (SWD) interface using SWD_DIO and SWD_CLK pins, fully compliant with ARM CoreSight standards. It is supported by NXP's MCUXpresso IDE, SEGGER J-Link, and CMSIS-DAP debuggers-enabling full run-control, trace, flash programming, and real-time variable inspection during development and validation of the MKE16F256VLH16.
