PIC18 Q10 Product Family
PIC® MCUs for Closed-loop Control
The PIC18 Q10 family of microcontrollers (MCUs) is optimized for robust, real-time control with integrated Intelligent Analog, configurable peripherals and 5V operation for increased noise immunity. They are well suited for a broad range of applications including industrial control, consumer, automotive, touch sensing and Internet of Things (IoT). Each device includes a full complement of Core Independent Peripherals (CIPs) for safety critical applications (CRC / Memory Scan, Windowed Watchdog Timer, and Hardware Limit Timer), PWMs and multiple communications interfaces. Additionally, the family offers Intelligent Analog peripherals including Zero Cross Detect (ZCD), on-chip comparators and an Analog-to-Digital Converter with Computation (ADC2).
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.
The Curiosity High Pin Count (HPC) Development Board (DM164136) supports the PIC18 Q10 family. Curiosity Development Boards are cost-effective, fully-integrated MCU development platforms. The development board includes an integrated programmer/debugger and requires no additional hardware to get started.
The Analog to Digital Converter with Computation (ADC2) 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 (ZCD) 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.
Complementary Waveform Generator (CWG) 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 (HLT) 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 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.
The CRC/SCAN module and the Windowed Watchdog Timer (WWDT) 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, the devices support the implementation of safety standards such as Class B and UL 1998.
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 users to maintain layout compatibility with older PIC® MCUs, even as new features are implemented.
