Microchip PIC18F86J10-I/PT: A Comprehensive Technical Overview
The Microchip PIC18F86J10-I/PT stands as a significant component within the expansive PIC18 microcontroller family, engineered to deliver a robust blend of performance, connectivity, and integration for complex embedded applications. This 8-bit microcontroller, built on Microchip's enhanced nanoWatt technology, is particularly suited for demanding designs where power efficiency, peripheral integration, and computational capability are paramount.
At its core, the device features a modified Harvard architecture C-based engine capable of operating at speeds up to 40 MHz, providing a substantial 10 MIPS performance. This processing power is adept at handling extensive control algorithms and data processing tasks. A critical element of its design is the advanced low-power management system. The microcontroller incorporates multiple oscillators, including a primary external clock and an internal oscillator block, which allows for rapid wake-up from low-power modes like Sleep and Idle, drastically reducing overall system power consumption.
Memory resources are substantial, with 128 KB of self-read/write capable Flash program memory and 3,808 bytes of RAM. This ample memory space supports the storage of sophisticated application code and manages data efficiently in complex, multi-tasking environments. Furthermore, the inclusion of 1,024 bytes of EEPROM data memory offers reliable non-volatile storage for critical parameters that must be retained even after a power cycle.

The peripheral set integrated into the PIC18F86J10-I/PT is both diverse and powerful, making it a highly system-centric solution. It features a 10-bit Analog-to-Digital Converter (ADC) with up to 16 channels, enabling precise acquisition of multiple analog signals. For communication, it is exceptionally well-equipped, offering several serial protocols: two Enhanced Universal Synchronous Asynchronous Receiver Transmitters (EUSART), two Master Synchronous Serial Port (MSSP) modules supporting both SPI and I²C, and two Enhanced Controller Area Network (ECAN) modules. The inclusion of dual CAN buses is particularly notable for automotive and industrial networking applications requiring robust, noise-resistant communication.
Other key peripherals include five 8-bit timers and three 16-bit timers, along with two capture/compare/PWM (CCP) modules and one Enhanced CCP (ECCP) module, providing flexible waveform generation and timing control capabilities. The microcontroller is housed in a 80-pin TQFP package (I/PT), which is designed for surface-mount technology and offers a compact footprint for space-constrained PCB designs.
Operating from a 2.0V to 5.5V supply voltage, the PIC18F86J10-I/PT demonstrates excellent voltage flexibility, accommodating a wide range of power supply scenarios. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environmental conditions.
ICGOOODFIND Summary: The PIC18F86J10-I/PT is a high-performance, feature-rich 8-bit microcontroller from Microchip. Its standout features include dual ECAN modules for advanced networking, extensive memory, a wide operating voltage, and superior low-power management, making it an ideal choice for complex, connected embedded systems in automotive, industrial, and consumer applications.
