NXP Semiconductors MKE14F512VLL16

Overview

MKE14F512VLL16 from NXP Semiconductors is an ARM® Cortex®-M4 based microcontroller delivering up to 168 MHz operation with single-precision FPU, 512 KB ECC-protected flash, 64 KB ECC SRAM, and 64 KB FlexNVM for data storage and EEPROM emulation. It integrates three 12-bit ADCs (up to 16 channels each), four FlexTimer modules (32 PWM channels), and three LPUARTs-designed for industrial motor control, smart sensor nodes, and low-power HMI systems.

For engineers reviewing the MKE14F512VLL16 datasheet, MKE14F512VLL16 pinout, MKE14F512VLL16 application, or MKE14F512VLL16 equivalent, key selection considerations include its 100-pin LQFP package, absence of FlexCAN interface, support for Stop/VLPS mode wake-up via LPUART/LPSPI/LPI2C/ADC/CMP, and integrated ECC protection across flash and SRAM.

Technical Context

The MKE14F512VLL16 implements a full ARMv7-M architecture with Thumb®-2 ISA, DSP extensions, and hardware-accelerated multiply-accumulate operations. Its SCG clock system supports multiple internal/external sources-including 48 MHz FIRC (±1%), 8/2 MHz SIRC (±3%), 32 kHz OSC32, and PLL-with dynamic switching between run modes (HSRUN, RUN, VLPR) and deep-sleep states (Stop, VLPS).

Peripheral interconnectivity is managed by TRGMUX and DMAMUX, enabling flexible signal routing between 3× LPUART, 2× LPSPI, 2× LPI2C, 3× ADC, and 4× FTM without CPU intervention. The AWIC controller provides asynchronous wake-up from Stop/VLPS using dedicated low-power peripherals operating on SIRC or OSC32 clocks.

FAQ

What is the maximum operating frequency of the MKE14F512VLL16?

The MKE14F512VLL16 operates at up to 168 MHz using its ARM Cortex-M4 core with integrated single-precision floating-point unit. This frequency is achieved via the SCG clock generator and PLL configuration, and is validated across the full –40 °C to +105 °C temperature range and 2.7–5.5 V supply voltage window specified in the official NXP datasheet Rev. 4.1.

Does the MKE14F512VLL16 support CAN communication?

No, the MKE14F512VLL16 does not include any FlexCAN module. Unlike the MKE16F512VLL16 (one CAN) or MKE18F512VLL16 (two CAN), this variant omits CAN entirely-confirmed in Table 1 of the NXP datasheet Rev. 4.1 under "Communication" column showing "0" for FlexCAN count. Its serial connectivity relies on LPUART, LPSPI, and LPI2C interfaces.

What package type and pin count does the MKE14F512VLL16 use?

The MKE14F512VLL16 uses a 100-pin LQFP package (suffix "VLL"), measuring 14 mm × 14 mm × 1.4 mm with 0.5 mm pitch. This is explicitly defined in the ordering information table and package drawing 98ASS23308W referenced in the NXP KE1xF datasheet Rev. 4.1. It provides 89 GPIOs, including 8 high-drive outputs.

How does ECC memory protection work on the MKE14F512VLL16?

The MKE14F512VLL16 implements hardware ECC on both 512 KB flash and 64 KB SRAM, automatically correcting single-bit errors and flagging multi-bit errors. This is enabled by default and requires no software overhead. ECC coverage extends to FlexNVM and FlexRAM, ensuring data integrity for EEPROM emulation and critical runtime variables-even during extended operation in electrically noisy industrial environments.

Can the MKE14F512VLL16 operate in low-power Stop or VLPS modes with peripherals active?

Yes, the MKE14F512VLL16 supports peripheral operation in both Stop and VLPS modes. In Stop mode, ADC, CMP, LPTMR, RTC, and GPIO interrupts remain functional; in VLPS mode, LPUART, LPSPI, LPI2C, FlexIO, LPIT, and DMA also stay active-enabling wake-up on serial activity or analog thresholds. All low-power behavior is managed by the PMC and AWIC modules as documented in Section 2.1.8 of the datasheet.
