Compact Microcontroller (MCU) With Advanced Communication and Internal Level Shifters
The PIC18-Q20 family of MCUs offers configurable peripherals and advanced communication interfaces and supports multiple voltage domains for embedded systems that have several sensors. These MCUs are equipped with I3C® modules that have a fast communication rate, a high-speed 10-bit Analog-to-Digital Converter with Computation (ADCC), capacitive touch sensing and an 8-bit signal routing port to interconnect digital peripherals. This product family easily interfaces across multiple voltage domains without external components and supports 1V operation for I3C communication. With I3C support and the integrated level shifters, PIC18-Q20 MCUs are suitable for sensor interfacing in embedded designs with multiple voltage domains. Available in small 14- and 20- pin packages, the MCUs are well-suited as a I3C-to-I2C communication bridge or a companion MCU for larger IoT systems to perform housekeeping functions for an extensive range of space-sensitive applications and markets including automotive, industrial control, computing, consumer, medical, wearables, touch sensing and memory management applications.
Getting Started
Take your next idea to market with a development board that you can keep in your pocket. With full program and debug capabilities, the PIC18F16Q20 Curiosity Nano Evaluation Kit offers complete support for your next design.
The PIC18-Q20 family integrates with MPLAB® Code Configurator (MCC), a free software plug-in for our award-winning MPLAB X Integrated Development Environment (IDE), to provide a graphical interface to easily configure peripherals and functions specific to your application. To simplify I3C code development, MCC has I3C drivers with DMA support for data transfers to meet the high data throughput on the I3C bus. Code examples are also available to help you immediately start your development.
System Features
Advanced Communication Interfaces
I3C, I2C, UART, SPI
The PIC18-Q20 offers multiple communications such as I3C, I2C, SPI and UART. I3C offers higher communication rates, and lower power consumption and maintains backward compatibility with I2C. I3C helps designers meet the demanding market requirements to deliver IoT devices.
Support for Multiple Voltage Domains
MVIO
The Multi-Voltage I/O (MVIO) feature allows the MCU to interface with digital inputs or outputs at a different operating voltage than the rest of the device. The MVIO feature reduces system costs, design complexity and board space by replacing external level shifters with internal level shifters.
Configurable Analog
10-bit ADCC
The high-speed Analog-to-Digital Converter with Computation (ADCC) automates signal analysis and data acquisition functions simplifying real-time control and capacitive sensing designs.
Hardware Customization
Custom Logic and Interconnections
The 8-bit signal routing port interconnects digital peripherals without external pins, which enables rapid response to changing events in commonly used control systems. The Configurable Logic Cell (CLC) is a user-configurable peripheral for creating custom hardware-based logic functions, allowing you to integrate a combination of external and internal signals as inputs and connect on-board peripherals to reduce the number of external components needed for your design; this reduces your PCB footprint and overall system cost.
Design Flexibility
Configurable Timers, 16-bit PWM
The two customizable 16-bit Universal Timers (UTs) can be combined to make a larger timer to deliver advanced capabilities beyond those found on standard timer modules. The integrated, high-resolution 16-bit PWMs allow you to easily vary phase, duty cycle and offset event count with greater precision to provide advanced capabilities beyond those found on standard PWM modules.
