Take your next idea to market with a development board that you can keep in your pocket. With full program and debug capabilities, the PIC16F18446 Curiosity Nano Evaluation Kit offers complete support for your next design. The PIC16F18446 combines high-resolution analog, intelligent hardware peripherals and low-power features for sensor node applications.
The PIC16F18446 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.
Enhanced System Features
This family of products offer intelligent analog peripherals including Zero Cross Detect (ZCD), on-chip comparator and a 12-bit ADC2, automating Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling and threshold comparison.
Zero Cross Detect (ZCD)
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.
The 10-bit PWM provides edge-aligned output which can be used with the Complementary Waveform Generator.
Complementary Waveform Generator (CWG)
The 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.
Numerically Controlled Oscillator (NCO)
The 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.
Data Signal Modulator (DSM)
The Data Signal Modulator offers smooth signal switching. When paired with 16-bit PWM, LED dimming engine functionality is created.
Hardware Limit Timer (HLT)
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.
24-bit Signal Measurement Timer (SMT)
The 24-bit Signal Measurement Timer performs high-resolution measurements of any digital signal in hardware, resulting in near zero latency and high performance when decoding custom communications protocols or signaling.
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.
Windowed Watchdog Timer (WWDT)
The Windowed Watchdog Timer is a system supervisory circuit that generates a reset when software anomalies are detected within a configurable critical window.
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.
Advanced Memory Features
Memory Access Partition (MAP) supports customers in data protection and bootloader applications. Device Information Area (DIA) is a dedicated memory space for factory programmed device ID and peripheral calibration values.
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.
