The Microchip PIC18F25K80-E/SO stands as a prominent member of the enhanced PIC18F K80 family, representing a powerful and flexible 8-bit microcontroller solution engineered for a wide array of embedded control applications. Combining high computational performance with a rich set of integrated peripherals, low-power operation, and robust connectivity options, this MCU is a versatile choice for designers in industrial, automotive, and consumer markets.

Architectural Overview and Core Features

At the heart of the PIC18F25K80 lies an enhanced 8-bit CPU core with a 16-bit wide instruction path, enabling efficient and speedy execution of code. The device operates at up to 64 MHz, delivering a performance of 16 MIPS (Millions of Instructions Per Second), which is exceptional for an 8-bit architecture. This performance is crucial for handling complex control algorithms and real-time processing tasks.

A significant feature of this microcontroller is its substantial memory configuration. It is equipped with 96 Kbytes of self-read/write capable Flash program memory and 3896 bytes of RAM. This ample non-volatile memory allows for storing large application code and facilitates bootloader and data logging functionalities, where the application can write to its own program memory space—a capability not found in all MCUs.

Advanced Peripheral Integration

The PIC18F25K80-E/SO is distinguished by its highly integrated peripheral set, designed to minimize external components and reduce total system cost.

Analog-to-Digital Converter (ADC): It includes a high-performance 10-bit ADC with up to 28 channels, providing precise measurement capabilities for multiple analog sensors.

Communication Interfaces: A comprehensive suite of serial communication modules is onboard: EUSART (for UART), SPI, and I2C™. This ensures seamless connectivity with a vast ecosystem of sensors, displays, memory chips, and other peripherals.

Timers and CCP Modules: The device features multiple timers (including a 16-bit timer), and Capture/Compare/PWM (CCP) modules with enhanced PWM options, making it ideal for motor control, power conversion, and lighting applications.

mTouch Sensing: Integrated capacitive sensing (mTouch) hardware support allows for the easy implementation of robust touch interfaces without external components.

Low-Power and Robust Operational Characteristics

Engineered for efficiency, the PIC18F25K80 incorporates nanoWatt XLP (eXtreme Low Power) technology. This enables it to operate in power-sensitive applications, achieving very low currents in Run, Idle, and Sleep modes. This is critical for battery-powered and energy-harvesting devices.

The MCU is designed for demanding environments. It features a wide operating voltage range (2.0V to 5.5V) and an extended temperature range (-40°C to +125°C), ensuring reliable performance under voltage fluctuations and in harsh conditions. The E/SO suffix denotes that it is supplied in a 300-mil SOIC wide body package, suitable for automated assembly and providing robust physical connectivity.
