Robust MCUs for Compact Embedded Designs
The PIC18-Q40 series of microcontrollers (MCUs) makes it easy for you to customize your next space-constrained design. Packing a high level of sophistication into a small 14- or 20-pin package, these MCUs combine powerful, versatile and highly configurable Core Independent Peripherals (CIPs) with advanced interconnection capabilities to allow you to create custom application functions. Our comprehensive development tool suite with its Graphical User Interface (GUI) environment makes it easy to quickly customize combinations of CIPs and generate application code. These MCUs are well suited for remote medical care devices, wearables, consumer, automotive, industrial and Internet of Things (IoT). If you need the same level of MCU performance with additional analog features, PIC18-Q41 MCUs are an ideal solution.
Getting Started
Take your next idea to market with a cost-effective development board that you can keep in your pocket. With its full programming and debugging capabilities, the PIC18F16Q40 Curiosity Nano Evaluation kit (EV70C97A) offers complete support for your next design.
The PIC18-Q40 family is designed to integrate with MPLAB® Code Configurator (MCC), a free software plug-in for our award-winning MPLAB X Integrated Development Environment (IDE), that provides a graphical interface to easily configure peripherals and functions specific to your application. Code examples are also available to help you immediately start your development.
System Features
Responsive Operation
Core Independent Peripherals (CIPs)
CIPs enable smaller, lower-power MCUs to accomplish many timing-critical and core-intensive tasks in hardware without any intervention from the CPU. This reduces the use of Flash memory and frees up the CPU to focus on more complex system tasks or go to sleep to save power. Because you don’t need to create any additional code or use any extra discrete components, they simplify your design while also reducing power consumption, allowing for deterministic response times and decreasing validation time.
Improved System Performance
Direct Memory Access (DMA)
The PIC18-Q40 family features four Direct Memory Access (DMA) controllers to perform data transfers between all memory spaces and peripherals to boost system performance and improve power consumption.
Design Flexibility
16-bit PWM
Delivering advanced capabilities beyond those found on standard PWM modules, the integrated, high-resolution 16-bit PWMs allow you to easily vary phase, duty cycle and offset event count with greater precision. They offer dual independent outputs on the same time base, which helps simplify drive control in a variety of applications. The flexible serial communications interface options include a UART with support for Asynchronous, DMX, DALI and LIN protocols, plus higher-speed, stand-alone I2C and SPI modules.
Intelligent Analog
12-bit ADCC, 8-bit DAC, Zero Cross Detect (ZCD)
The on-chip intelligent analog peripherals enable you to develop simple, efficient solutions. They include a Zero Cross Detect (ZCD) module, comparators, two 8-bit Digital-to-Analog Converter (DACs) and a 12-bit Analog-to-Digital Converter with Computation (ADCC) that automates Capacitive Voltage Divider (CVD) techniques for implementing advanced touch sensing, averaging, filtering, oversampling and automatic threshold comparison.
Reduced Costs and Board Space
Custom Logic
To create customized hardware-based logic functions, the four user-configurable Custom Logic peripherals let you specify combinations of signals as inputs to a logic function and internally connect peripherals such as timers, Pulse-Width Modulators (PWMs), serial ports and I/O pins for easy hardware customization. Because the Custom Logic peripheral enables a higher level of integration without the need for any external components, you can reduce your PCB footprint and system costs.
Power-Conserving Functionality
IDLE, DOZE, Peripheral Module Disable (PMD)
IDLE and DOZE low-power modes allow you to optimize your application for device performance and power consumption. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption.
Layout Flexibility
Peripheral Pin Select (PPS)
Peripheral Pin Select (PPS) provides ultimate flexibility when routing digital signals to device pins. With PPS, any digital peripheral can be connected to any I/O pin on the fly for a customized layout. This allows you to maintain layout compatibility with older PIC® MCUs, even as new features are implemented.
Safety First
Functional Safety Ready
The CRC/SCAN module and the Windowed Watchdog Timer (WWDT) work in tandem to provide the necessary tools to incorporate functional safety into your application. By ensuring the integrity of the program Flash contents, the devices support the implementation of safety standards such as Class B and UL 1998.
