Housed in a 28-SSOP package, this device is engineered for a wide array of embedded control applications, offering a robust set of core independent peripherals (CIPs) that minimize CPU intervention and boost system efficiency.
Core Architectural Features
At its heart, the PIC16F1718 leverages an enhanced Harvard architecture with a 35-instruction set. It operates at a maximum frequency of 32 MHz, delivering a performance of 8 MIPS. The device is equipped with 14 KB of Flash program memory, 1 KB of RAM, and 256 bytes of data EEPROM, providing ample space for both code and critical data storage. Its wide operating voltage range (2.3V to 5.5V) and extensive temperature range make it suitable for consumer, industrial, and automotive applications.
Advanced and Core Independent Peripherals (CIPs)
A key strength of this microcontroller lies in its rich suite of integrated peripherals designed to handle complex tasks autonomously.
Analog Capabilities: It features a 12-bit ADC with Computation (ADC²) module. This advanced ADC can perform math operations (like averaging, filtering, and threshold comparison) on its acquired data without CPU cycles, significantly optimizing power consumption in sensor-based applications.
Waveform Control: It includes multiple complementary waveform generators, such as:
1x 8-bit DAC
2x 8-bit PWM
1x 10-bit PWM
A Complementary Output Generator (COG) that provides dead-band control and fault protection for advanced motor control and power conversion systems.
Communication Interfaces: Standard serial communication is supported via EUSART (UART), SPI, and I²C modules, enabling seamless connectivity with a vast ecosystem of sensors, displays, and other ICs.
Timing and Control: The module includes multiple timers (Timer0, Timer1, etc.), a Windowed Watchdog Timer (WWDT) for enhanced reliability, and a Hardware Limit Timer (HLT) for safety-critical applications.
Hardware Security and Robustness
The PIC16F1718 is built with system integrity in mind. It includes a Cyclic Redundancy Check (CRC) memory scanner for monitoring Flash memory health, a Memory Access Partition (MAP) feature to define application and boot sections for secure firmware updates, and a Programmable High/Low-Voltage Detect (HLVD) module. These features are crucial for applications requiring functional safety and robust operation in electrically noisy environments.
Application Guide
The combination of these features opens doors to numerous applications:
Motor Control: The COG and multiple PWMs make it ideal for brushless DC (BLDC) and stepper motor control in appliances, drones, and industrial automation.
Sensor Signal Conditioning: The ADC² and on-chip DAC are perfect for directly interfacing with and processing analog sensor signals (e.g., temperature, pressure, light) in IoT nodes and smart transducers.
Power Conversion: Used in switch-mode power supplies (SMPS), battery chargers, and digital power converters.
Consumer Electronics: Suitable for touch sensing interfaces (using its capacitive sensing module), LED lighting control, and general-purpose control tasks.
