PIC18-Q10 Product Family
PIC® MCUs for Closed-Loop Control
Design a fast, reliable real-time control system tailored to your application with the newest members of the PIC18-Q10 product family. You can use the Configurable Logic Cells (CLCs) available on the 28-pin PIC18F26Q10 and PIC18F27Q10 MCUs and 40-pin PIC18F45Q10, PIC18F46Q10 and PIC18F47Q10 MCUs to create custom hardware-based logic functions. All devices in this family contain integrated Intelligent Analog, configurable peripherals and 5V operation for increased noise immunity. Each device also includes a full complement of Core Independent Peripherals (CIPs), including Cyclic Redundancy Check/Memory Scan (CRC/Scan), Windowed Watchdog Timer (WWDT) and Hardware Limit Timer (HLT) for use in safety-critical applications, as well as Pulse-Width Modulators (PWMs) and multiple communications interfaces. The Intelligent Analog peripherals include Zero Cross Detect (ZCD), on-chip comparators and an Analog-to-Digital Converter with Computation (ADC2). These MCUs are well suited for a broad range of industrial control, consumer, automotive, capacitive touch sensing and Internet of Things (IoT) applications.
Take your next idea to market with a development board that you can keep in your pocket. With full program and debug capabilities, the PIC18F47Q10 Curiosity Nano Evaluation Kit offers complete support for your next design.
The PIC18-Q10 family is also supported by MPLAB® Code Configurator (MCC), a free software plug-in that provides a graphical interface to configure peripherals and functions specific to your application. MCC is incorporated into our award-winning Integrated Development Environments (IDEs), the downloadable MPLAB X IDE and the cloud-based MPLAB Xpress IDE. Several code examples are available to help you get started immediately with your development.
The PIC18-Q10 family of MCUs feature Core Independent Peripherals that provide the ability to accomplish tasks in hardware while freeing up the Central Processing Unit (CPU) to do other tasks or go to sleep to save power. The hardware-based peripherals offload timing-critical and core-intensive functions from the CPU, allowing it to focus on more complex tasks within the system. This decreases system complexity by eliminating additional code and external components, reduces power consumption, allowing for deterministic response time as well as decreased validation time.
The products offer Intelligent Analog peripherals including Zero Cross Detect (ZCD), on-chip comparators and a 10-bit ADC with Computation (ADC2) automating Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling and automatic threshold comparison.
Building Blocks for Function Enablement
The Analog to Digital Converter with Computation helps accelerate common math tasks normally done in software by providing post-processing functions like averaging, low-pass filter, oversampling and threshold comparison.
The Zero Cross Detect module can monitor AC line voltage and indicate zero crossing activity. This information is made directly available to the on-board Waveform Generation peripherals for use in TRIAC control applications, greatly reducing both CPU demand and overall development cost by lowering the bill of materials.
The Complementary Waveform Generator provides a complementary waveform with rising and falling edge dead band control, enabling high-efficiency synchronous switching with no processor overhead. The CWG also incorporates auto shutdown, auto restart and can interface directly with other peripherals/external inputs.
The Hardware Limit Timer can detect faults in motors, power supplies, and other external devices. It can automatically notify the system to make provisions to shut down and/or safely restart.
The CRC/SCAN module and the Windowed Watchdog Timer work in tandem to provide engineers with the tools necessary to incorporate functional safety into their application. By ensuring the integrity of the program FLASH contents, PICF19197 devices support the implementation of safety standards such as Class B and UL 1998.
Peripheral Pin Select 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 users to maintain layout compatibility with older PIC® MCUs, even as new features are implemented.
The Configurable Logic Cell offers hardware-based combinational and sequential logic functions to simplify and accelerate many common tasks. The CLC can also be used as “glue” logic between peripherals, eliminating the need for CPU intervention during steady-state activity in complex control loops.
IDLE and DOZE low-power modes allow applications to optimize device performance and power consumption. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption. The device features the industry-leading eXtreme Lower Power (XLP) technology.
