These peripheral ports allow for connectivity with devices such as keyboards, memory cards, display, LCD and other devices. USB, LED, I2C, SPI and other communication protocols can also be implemented using these devices. Also, the device can be used for networking applications and other multitasking programming.

PIC18C658-I/L Working Principle

The PIC18C658-I/L microcontroller uses an 8-bit single-cycle instruction set. This core simplifies instruction execution while providing maximum performance. All instructions are executed in one single clock cycle when certain conditions are met, particularly when the processor\'s internal clock frequency is greater than the instruction frequency. To improve performance, the device has various limited instructions that can be used to optimize the instructions, depending on the application.

The PIC18C658-I/L has 32 general purpose registers that are user-accessible. The registers have 16 visible locations that can survive a power cycle. The other 16 locations are mirrored in the onboard RAM area. These registers help in controlling and tracking the operation of the microcontroller. These registers can also be used to control and store processor status and library status.

The device is powered by a +3.3V power supply. The power supply should meet the specified requirements of the specified applications. The power control system allows the user to monitor and control the power supplied to the microcontroller. The timing of the CPU can be controlled using the DC and timer peripheral. The DC peripheral can be used to identify and control the duration of the CPU clock.

Interrupts can be generated by the PIC18C658-I/L microcontroller. These interrupts can be programmed for use in enacting several operations at once. The priority of the interrupts can be adjusted, so that high priority and time constrained operations can be handled without compromising the performance of other operations. The interrupts also work with several other peripherals of the device, aiding in enhanced speed control and event control.

The PIC18C658-I/L integrated an analog-to-digital (A/D) converter, which converts analog signals into digital signals. This is a 10-bit converter and is used in various applications such as automative, home automation, medical, measurement and various other areas. This device allows the microcontroller to measure the analog signals and perform further operations based on the obtained values.

The embedded memory of the PIC18C658-I/L consists of 8Kbytes of Flash memory, 8Kbytes of EEPROM and 256 bytes of RAM. The Flash memory can be used for storing the microcontroller program code. The EEPROM can be used for storing user\'s data, where the data can be used for calibration and configuration purposes. The RAM can be used for storing the intermediate values and results of the applied operations.
