8-Bit MCUs

PIC16F1709 Product Family

Flexible Intelligence with On-Board Analog

The PIC16F1709 MCU family combines the intelligence and flexibility of our cutting edge Core Independent Peripherals with the cost-effective integration of op amps, comparators, and other Intelligent Analog peripherals.

Core Independent Peripherals take 8-bit performance to a new level by performing system functions autonomously, with much lower latency and power consumption than interrupt-based task handling. Additionally, they simplify the implementation of complex control systems by allowing designers to isolate each system function for easy development and troubleshooting.

The family also offers a rich set of analog peripherals, including Dual Op Amps to drive analog control loops, amplify signals from sensors, and perform basic signal conditioning. Other on-chip Intelligent Analog features include internal High-Speed Comparators, 10-bit ADC and 8-bit DAC. These 14-, 20-, 28-, and 40-pin devices also feature Zero Cross Detect, which simplifies TRIAC control, synchronized switching control, and timing. Together, they enable designers to reduce system cost and board space while improving EMI/EMC performance.

Choose Your Path with Flexible Routing Features

PIC16F1709 MCUs offer Peripheral Pin Select (PPS), which gives system developers the ability to configure any digital peripheral to any I/O pin. This flexible pin mapping feature provides increased freedom and optimization of the MCU’s peripheral resources that designers use in their application. When combined with the Configurable Logic Cell for peripheral-to-peripheral connections, the PPS helps enable complex functions, simplifies legacy system migration and provides optimized PCB tracing for improved board space usage and highest signal integrity for designs that require it.

 


Getting Started

The Curiosity Development Board (DM164137) and the Curiosity High Pin Count (HPC) Development Board (DM164136) support the PIC16F1709 product 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 PIC16F1709 product 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. Additionally, several Xpress code examples are available to help designers start development immediately.

 


Building Blocks for Real-Time Control

Intelligent Analog
+

Intelligent Analog peripherals help significantly reduce BOM cost, PCB size, and system noise. On-chip op amps, high speed comparators, and robust ADC peripherals allow designers to significantly reduce the component count in their analog signal chain.

Zero Cross Detect (ZCD)
+

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.

Numerically Controlled Oscillator (NCO)
+

Numerically Controlled Oscillator is a precision linear frequency generator with fine step resolution. It provides high-resolution oscillator capabilities to control applications such as lighting ballast, radio and tone generator.

More Information

Configurable Logic Cell (CLC)
+

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.

More Information

Peripheral Pin Select (PPS)
+

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.
