FAQ

What is the maximum operating frequency of the MK40DX64VLH7?

The MK40DX64VLH7 operates at a maximum CPU frequency of 72 MHz. This is achieved using the internal multipurpose clock generator with an external 3–32 MHz crystal oscillator and the FEE (FEI → FBE → FEE) clock mode sequence. The 72 MHz system clock supports real-time execution of motor control algorithms and full-speed USB data transfers without external clock multiplication.

Does the MK40DX64VLH7 support USB device and host functionality?

Yes, the MK40DX64VLH7 integrates a USB full-/low-speed On-The-Go controller with an on-chip transceiver. It supports both device and host roles without requiring an external PHY. The MK40DX64VLH7 implements the USB 2.0 specification and includes dedicated USB voltage regulator (VREG) and control logic for session request protocol (SRP) and host negotiation protocol (HNP), enabling portable diagnostic tools and embedded host peripherals.

What analog features does the MK40DX64VLH7 provide for sensor interfacing?

The MK40DX64VLH7 provides two independent 16-bit SAR ADCs, each with an integrated programmable gain amplifier (PGA) offering gains of 1, 2, 4, 8, 16, 32, or 64. It also includes a 12-bit DAC, three analog comparators (each with a 6-bit DAC and programmable reference), and a precision voltage reference. These features enable direct high-fidelity acquisition of low-level sensor signals such as thermocouples, strain gauges, and current shunts without external signal conditioning.

Is the MK40DX64VLH7 qualified for automotive applications?

The MK40DX64VLH7 is specified for an ambient temperature range of –40 to 105°C and carries the 'V' suffix denoting extended temperature qualification. While not AEC-Q100 certified out-of-box, its electrical and thermal specifications meet common automotive body electronics requirements. Customers implementing the MK40DX64VLH7 in automotive systems must perform full qualification per their OEM's standards, including board-level stress testing and functional safety analysis per ISO 26262.

What low-power modes are available on the MK40DX64VLH7?

The MK40DX64VLH7 offers multiple low-power modes including VLPR (Very-Low-Power Run), VLPW (Very-Low-Power Wait), STOP, VLPS (Very-Low-Power Stop), LLS (Low-Leakage Stop), and VLLS (Very-Low-Leakage Stop) variants. In VLLS1 mode, current consumption drops to 1.47 µA @ 3.0 V and –40 to 25°C, while retaining RAM and selected peripherals. Wake-up sources include GPIO, RTC alarm, CAN bus activity, and low-power timer events - enabling energy-efficient battery-operated designs.
