MCUs bridge I3C across voltage domains
Microchip’s PIC18-Q20 MCUs integrate up to two I3C peripherals and Multi-Voltage I/O (MVIO) in 14- and 20-pin packages as small as 3×3 mm. Well suited for sensor interfacing, real-time control, and connectivity applications, they simplify communication across multiple voltage domains with minimal external circuitry.
Compared to I2C, I3C provides higher data rates and lower power consumption while remaining backward compatible with legacy systems. The MCUs operate across three independent voltage domains, with MVIO-enabled pins supporting I3C communication down to 1.0 V. Additional integration includes a 10-bit ADC with computation, capacitive touch sensing, and an 8-bit signal routing port for flexible peripheral interconnect.
The PIC18-Q20 series can process sensor data, manage low-latency interrupts, and perform system status reporting, reducing the workload on a host MCU in larger systems. These devices are supported by Microchip’s hardware and software development ecosystem, including the PIC18F16Q20 Curiosity Nano Evaluation Kit for rapid prototyping.
Now in production, the PIC18-Q20 MCUs are available from Microchip and its authorized distributors.
