8-Bit MCUs

PIC16F18346 Product Family

Peripheral Integration to Enable Functions

The PIC16F18346 products feature a high level of core independent peripherals that can be combined to perform a wide variety of functions without the core. The integration of peripherals brings a new level of interconnection that enables unsurpassed flexibility in creating functions for a wide range of applications, including consumer electronics, Internet of Things (IoT) and wearable technology applications. These products also include new power-conserving functionality, including Idle/Doze operating modes and Peripheral Module Disable (PMD), in addition to eXtreme Low Power (XLP) technology.

Easy Complementary Output Generation

Any of the 10-bit Pulse Width Modulations (PWMs) or Capture/Compare/PWMs (CCP) can be combined with the Complementary Waveform Generator (CWG) which enables automated complementary output control with control of dead-band and auto-shutdown modes. Once configured, the complementary outputs run completely independent of the core, allowing the core to perform other tasks.

Integrated Analog

The onboard 10-bit ADC, 5-bit DAC, internal voltage references and comparators can be connected internally to create closed-loop feedback without requiring pins or PCB space or can be used for other functions within the applications. The versatile 10-bit ADC can be used to implement buttons or sliders using Microchip's mTouch® Capacitive Sensing solution.

Increased Low-Power Functionality

New 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 lowering power consumption.

Flexible PCB Routing

The Peripheral Pin Select (PPS) functionality allows for I/O pin remapping of the digital peripherals for increased flexibility and ease of PCB layout and improved utilization by accessing multiple peripherals on the same I/O port.

Communicate With Others

These products include SPI, I2C and EUSART peripherals, which enable a wide range of communication protocols. This allows for intelligent applications where communication with a host or master device is required.


Getting Started

The Curiosity Development Board (DM164137) supports the PIC16F18346 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 PIC16F18346 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

10-bit PWM

The 10-bit PWM provides edge-aligned output which can be used with the Complementary Waveform Generator.

Complementary Waveform Generator (CWG)

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.

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.

More Information

Power Conserving Functionality

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.

Capture Compare PWM (CCP)

The Capture Compare PWM provides 16-bit signal capture and compare, as well as 10-bit PWM output functionality.

Closed Loop Control (CLC)

With the additional 10-bit ADC, 5-bit DAC and Comparator, control loops for closed loop feedback control can be created or used for other functions within the application. Using Microchip's mTouch Capacitive Sensing solution, the 10-bit ADC can be used to create buttons or sliders.
