Technical Details & Description

What this Kinetis K40 brings to the board

The NXP MK40DN512VLL10 is a 32-bit ARM Cortex-M4 microcontroller from the Kinetis K40 series, clocked at 100 MHz. It packs 512 KB of Flash and 128 KB of SRAM, with a hardware floating-point unit and DSP instructions for math-heavy tasks like motor-control loops or audio processing. The integrated LCD controller is the series' standout — it drives a segment display directly, saving an external driver IC on a control-panel board.

Memory and peripherals — what fits in the 100-LQFP

With 512 KB Flash you can hold a full RTOS, a TCP/IP stack, and a modest application image. The 128 KB SRAM leaves room for double-buffered display data or a decent audio buffer. The 100-LQFP package brings out 64 general-purpose I/Os, plus CAN, USB OTG, multiple SPI and UART interfaces, and an I²S audio port. The 34-channel 16-bit ADC and single 12-bit DAC cover analog sensing and control without external converters.

Temperature range and supply — industrial environments

NXP lists the MK40DN512VLL10 as Active.

Frequently asked questions

What is the core of MK40DN512VLL10?

It uses an ARM Cortex-M4 core with a 32-bit single-core architecture, including a hardware floating-point unit and DSP instructions.

What are equivalent or alternative parts to MK40DN512VLL10?

Pin-compatible alternatives within the Kinetis K40 family include variants with different Flash and SRAM sizes, such as the MK40DN256VLL10 (256 KB Flash) or MK40DN512VMC10 (same die in a 121-MAPBGA package). For a direct drop-in replacement, verify the exact memory and package match against your BOM.

What is MK40DN512VLL10's listed speed?

The core runs at 100 MHz, which is the maximum clock for this part.
