FAQ

What is the maximum operating frequency of the MKL26Z32VLH4 core?

The MKL26Z32VLH4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is supported across the full 1.71–3.6 V supply range and –40 to +105°C temperature range, with zero wait-state flash execution ensuring deterministic timing for real-time control loops. The MKL26Z32VLH4 also supports variable clock scaling down to 4 MHz in very-low-power run (VLPR) mode for further energy optimization.

Does the MKL26Z32VLH4 include an integrated USB transceiver?

Yes, the MKL26Z32VLH4 integrates a full-/low-speed USB 2.0 On-The-Go controller with a physical-layer transceiver and an internal 5 V-to-3.3 V regulator. This eliminates the need for external USB PHY ICs, level shifters, or discrete voltage regulators in USB device or host implementations. The MKL26Z32VLH4 supports standard USB classes including CDC ACM, HID, and MSC without additional silicon.

What low-power modes are supported by the MKL26Z32VLH4, and what is the lowest current draw?

The MKL26Z32VLH4 supports nine low-power modes, including VLLS0 (Very-Low-Leakage Stop Mode 0) with full register and RAM retention. In VLLS0 mode at 25°C and 3.0 V, the MKL26Z32VLH4 draws as little as 0.4 µA-verified in production characterization-and wakes in 4.5 µs. This enables multi-year operation on coin-cell batteries in periodic-sensing applications such as environmental monitors or asset trackers.

Can the MKL26Z32VLH4 perform capacitive touch sensing without external components?

Yes, the MKL26Z32VLH4 includes a dedicated Touch Sense Interface (TSI) module capable of self-capacitive touch sensing on up to 16 inputs using only PCB traces-no external RC networks or dedicated touch controller ICs required. The TSI engine performs charge-transfer measurement in hardware, supports automatic calibration, and operates with <1 µA average current during active scanning, making it ideal for battery-powered keypads and control panels.

What is the ADC resolution and sampling capability of the MKL26Z32VLH4?

The MKL26Z32VLH4 integrates a 16-bit successive-approximation register (SAR) ADC with up to 16 input channels, programmable gain amplifier (PGA), and hardware averaging. It achieves up to 1 MSPS sampling rate with configurable conversion time and supports both single-ended and differential inputs. The ADC operates across the full –40 to +105°C range with guaranteed INL of ±1.5 LSB and DNL of ±0.75 LSB, enabling precision measurements in industrial and medical applications using the MKL26Z32VLH4.
