Technical Context

The MK40DX128VMD10 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC operations, delivering 1.25 Dhrystone MIPS per MHz. Its memory subsystem includes 128 KB on-chip flash (FlexMemory configuration), 16 KB SRAM, and 4 KB FlexRAM - enabling in-field reconfiguration of data/program partitioning. The device uses a multi-purpose clock generator with 3–32 MHz crystal oscillator support and integrated 32 kHz RTC oscillator.

System-level features include a 16-channel DMA controller supporting 63 request sources, memory protection unit (MPU) with multi-master arbitration, and eight low-power modes (including VLLS1–VLLS3 sub-modes). Analog integration comprises two independent 16-bit SAR ADCs each with programmable gain amplifier (up to ×64), two 12-bit DACs, three analog comparators with internal 6-bit DACs, and transimpedance amplifiers - all operating across the full 1.71–3.6 V supply range.

FAQ

What is the maximum operating frequency of the MK40DX128VMD10?

The MK40DX128VMD10 operates at up to 100 MHz using its ARM Cortex-M4 core with DSP extensions. This frequency is achievable across the full -40°C to +105°C ambient temperature range when supplied with 1.71–3.6 V, and is validated in the K40 Sub-Family Data Sheet Rev. 3 (2013) under FEI and FEE MCG modes. The MK40DX128VMD10 maintains timing compliance without derating in industrial temperature conditions.

Does the MK40DX128VMD10 support USB device functionality without an external transceiver?

Yes, the MK40DX128VMD10 integrates a full-speed/low-speed USB On-The-Go controller with an on-chip transceiver. It supports USB device mode directly using the USB_DP and USB_DM pins, requiring only a 1.5 kΩ pull-up resistor on DP for enumeration. No external PHY is needed, as confirmed in Section 6.8.1 of the K40 Sub-Family Data Sheet for the MK40DX128VMD10.

How much SRAM and FlexRAM does the MK40DX128VMD10 include?

The MK40DX128VMD10 includes 16 KB of general-purpose SRAM and 4 KB of FlexRAM. The FlexRAM is part of the FlexMemory subsystem and can be configured as additional RAM or as EEPROM emulation space. This configuration is software-controlled and persistent across resets, as documented in the memory map section of the MK40DX128VMD10 reference manual.

Is the MK40DX128VMD10 pin-compatible with other K40 family members?

No, the MK40DX128VMD10 is not pin-compatible with other K40 variants due to its 144-pin MAPBGA (MD) package. For example, the MK40DX128VLQ10 uses a 144-pin LQFP package with different mechanical dimensions and thermal characteristics. Pin assignments differ significantly between MAPBGA and LQFP variants, requiring unique PCB layouts for each package type.

What analog peripherals are integrated into the MK40DX128VMD10?

The MK40DX128VMD10 integrates two independent 16-bit SAR ADCs (each with programmable gain amplifier up to ×64), two 12-bit DACs, three analog comparators (each with internal 6-bit DAC and programmable reference), two transimpedance amplifiers, and a voltage reference module. All analog blocks operate across the full 1.71–3.6 V supply range and are specified in Sections 6.6.1–6.6.4 of the K40 Sub-Family Data Sheet for the MK40DX128VMD10.
