Product details
Overview
MKE14F256VLH16 from NXP Semiconductors is a 64-pin LQFP ARM® Cortex®-M4 microcontroller operating up to 168 MHz with single-precision FPU, 256 KB flash (ECC-protected), 32 KB SRAM (ECC-protected), and integrated FlexNVM for EEPROM emulation - deployed in industrial motor control, smart sensors, and low-power HMI systems.
For engineers reviewing the MKE14F256VLH16 datasheet, MKE14F256VLH16 pinout, MKE14F256VLH16 application, or MKE14F256VLH16 equivalent, key selection criteria include its 64-LQFP package, zero FlexCAN channels, 58 GPIOs (8 high-drive), triple 12-bit ADCs (1 MSPS), and support for Stop/VLPS low-power wake-up via LPUART/LPSPI/LPI2C.
Technical Context
The MKE14F256VLH16 implements an ARMv7-M architecture with Thumb®-2 ISA, delivering 1.25 Dhrystone MIPS/MHz and DSP extensions for real-time signal processing. Its memory subsystem includes ECC on flash, SRAM, and FlexNVM, plus 8 KB I/D cache to mitigate latency penalties during burst accesses.
Power management is governed by the PMC with seven operational modes (HSRUN, RUN, VLPR, WAIT, VLPW, STOP, VLPS); critical peripherals like LPUART, LPSPI, LPI2C, CMP, and ADC remain functional in STOP/VLPS using SIRC or OSC32 clocks, enabling sub-μA wake-up capability without external components.

FAQ
What is the maximum operating frequency of the MKE14F256VLH16?
The MKE14F256VLH16 operates at up to 168 MHz using its ARM Cortex-M4 core with integrated PLL. This frequency is achievable with proper power supply decoupling and thermal management per NXP's design guidelines in Section 6.1.2 of the datasheet. The MKE14F256VLH16 maintains full peripheral functionality-including FPU, DSP, and ECC-across its entire speed range.
Does the MKE14F256VLH16 support CAN communication?
No, the MKE14F256VLH16 does not include FlexCAN modules. Per Table 1 in the KE1xF datasheet Rev. 4.1, this variant is explicitly designated with "0" FlexCAN channels. For CAN-enabled equivalents, consider the MKE16F256VLH16, which shares the same 64-LQFP package and pinout while adding one FlexCAN 2.0B module.
How much SRAM and flash memory does the MKE14F256VLH16 have?
The MKE14F256VLH16 integrates 256 KB of program flash memory and 32 KB of SRAM - both protected by error-correcting code (ECC). It also includes 64 KB of FlexNVM and 4 KB of FlexRAM for EEPROM emulation. These memory resources are fully accessible at CPU clock speed with zero wait states, as confirmed in Section 2.1.4 of the datasheet.
What low-power modes are supported by the MKE14F256VLH16?
The MKE14F256VLH16 supports seven power modes managed by the Power Management Controller (PMC): HSRUN, RUN, VLPR, WAIT, VLPW, STOP, and VLPS. In STOP and VLPS modes, peripherals including LPUART, LPSPI, LPI2C, ADC, CMP, and RTC remain active using SIRC or OSC32 clocks - enabling wake-up with sub-microsecond latency without external circuitry.
Is there a built-in bootloader in the MKE14F256VLH16?
Yes, the MKE14F256VLH16 includes a 16 KB boot ROM with a production bootloader supporting UART, I²C, and SPI interfaces. This allows firmware updates in the field without a debugger or external programmer. Boot source selection is controlled via FOPT register bits and BOOTCFG0 pin state, as detailed in Section 2.1.5 of the datasheet.
