For engineers reviewing the MK40DX256VMD10 datasheet, MK40DX256VMD10 pinout, MK40DX256VMD10 application, or MK40DX256VMD10 equivalent, key selection criteria include its -40°C to +105°C extended temperature rating, 1.71–3.6 V supply range, FlexNVM capability for data logging, and QFP-64 package compatibility with legacy Kinetis designs.
Technical Context
The MK40DX256VMD10 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC operations, paired with a multi-purpose clock generator supporting crystal oscillators at 3–32 MHz and 32 kHz. Its memory subsystem includes non-volatile FlexNVM (256 KB) and FlexRAM (4 KB), enabling EEPROM-like wear leveling without external components.
System-level features include a 16-channel DMA controller servicing up to 63 request sources, memory protection unit (MPU) with multi-master arbitration, and low-power modes (VLPS/VLLS) achieving sub-1 μA stop-current at 3.0 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| K22FN512VLH12 | ARM Cortex-M4F (FPU), 512 KB flash, 120 MHz, same 64-LQFP package but higher voltage min (1.71 V vs. 1.71 V), identical peripheral set except no FlexMemory. | Lacks FlexNVM/FlexRAM - requires external EEPROM for data logging; better suited for floating-point math-intensive tasks. | Select when FPU-enabled algorithm acceleration is critical and external nonvolatile storage is acceptable. |
| MKE15Z256VLH7 | ARM Cortex-M0+, 256 KB flash, 72 MHz, 64-LQFP, lower power (1.71–3.6 V), no CAN FD, only one CAN interface, no USB OTG. | Reduced peripheral count and no USB/second CAN - targets cost-sensitive, low-complexity body electronics. | Select for simpler control tasks where CAN redundancy and USB host capability are unnecessary. |
Compared with MK40DX256VMD10, K22FN512VLH12 offers higher performance and flash but removes FlexMemory flexibility, while MKE15Z256VLH7 reduces cost and power at the expense of dual-CAN and USB functionality - making MK40DX256VMD10 optimal for mixed-signal, dual-network industrial edge nodes requiring field-upgradable data storage.

The MK40DX256VMD10 achieves 1.25 Dhrystone MIPS per MHz, delivering 125 DMIPS at full speed.
Does the MK40DX256VMD10 support USB device and host functionality?
Yes, the MK40DX256VMD10 integrates a USB full-/low-speed On-The-Go (OTG) controller with an on-chip transceiver, enabling both device and host roles without external PHY components. It supports USB CDC, HID, and mass storage classes. The MK40DX256VMD10 requires only standard USB termination and a 1.5 kΩ pull-up resistor on USB_DP for device enumeration.
What type of nonvolatile memory does the MK40DX256VMD10 include beyond main flash?
The MK40DX256VMD10 includes FlexMemory: 256 KB of FlexNVM (emulating EEPROM/flash with configurable partitioning) and 4 KB of FlexRAM (battery-backed or software-managed SRAM). This architecture allows reliable data logging, parameter storage, and firmware updates without external memory chips - a key differentiator of the MK40DX256VMD10 within the Kinetis family.
How many CAN interfaces does the MK40DX256VMD10 provide, and what protocol versions are supported?
The MK40DX256VMD10 provides two independent Controller Area Network (CAN) modules, each compliant with ISO 11898-1 (CAN 2.0B) and supporting bit rates up to 1 Mbps. Both modules support standard and extended frame formats, loopback mode for self-test, and hardware timestamping - making the MK40DX256VMD10 suitable for dual-bus automotive and industrial network gateways.
Is the MK40DX256VMD10 pin-compatible with other Kinetis K40 devices?
Yes, the MK40DX256VMD10 in the 64-pin LQFP (VMD) package shares identical pinout and footprint with other K40 devices in the same VMD variant, including MK40DX128VMD10 and MK40DN512VMD10. This enables hardware scalability across flash sizes and memory configurations without PCB redesign - a verified compatibility documented in the K40 Sub-Family Data Sheet Rev. 3.
