Microchip PIC18F1320-I/P 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC18F1320-I/P is a high-performance 8-bit microcontroller from Microchip Technology’s renowned PIC18 family. Housed in a 18-pin PDIP package, this device is engineered to deliver a powerful blend of processing capability, energy efficiency, and peripheral integration, making it a versatile solution for a wide array of embedded control applications.

At its core, the microcontroller features an enhanced PIC18 architecture capable of operating at speeds up to 40 MHz, executing complex instructions with a single-cycle fetch for most. This ensures robust performance for time-critical tasks. A significant advantage of this architecture is its C compiler optimization, which simplifies software development and reduces code size.

Memory resources include 8 KB of Flash program memory and 256 bytes of RAM, providing ample space for application code and data handling. The 256 bytes of EEPROM offer reliable non-volatile storage for critical data that must be retained even after a power cycle, such as calibration constants or user settings.

The peripheral set is a key strength of the PIC18F1320. It integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 11 input channels, enabling precise measurement of analog sensors. For timing and control, it includes multiple timers, including a 16-bit timer, and Enhanced CCP (Capture/Compare/PWM) modules essential for generating PWM signals to control motors or LEDs. Communication is facilitated through MSSP (Master Synchronous Serial Port) modules, supporting both I²C and SPI protocols for interfacing with a vast ecosystem of sensors, memories, and other peripherals.

Application Guide

The combination of its feature set and compact form factor makes the PIC18F1320-I/P ideal for numerous applications:
