At its core, the device operates with the enhanced PIC18 CPU core, which features a 16-bit instruction set and an 8-bit data path. This core can execute instructions at speeds up to 40 MHz, achieving a performance level of 10 MIPS. A key architectural advantage is the hardware multiplier that accelerates mathematical computations, a critical feature for data processing tasks. The microcontroller is equipped with 128 KB of self-programmable Flash memory and 3,904 bytes of RAM, providing ample space for sophisticated application code and data handling.
A defining characteristic of the PIC18F86J15 is its integrated CAN 2.0B module. This controller area network module is essential for developing robust networked systems, particularly in automotive and industrial automation environments where reliable, noise-resistant serial communication is paramount. Complementing this are multiple other serial communication peripherals, including EUSART, SPI, and I2C modules, offering designers flexible options for interfacing with a vast ecosystem of sensors, memories, and other peripherals.
The analog capabilities of this MCU are equally impressive. It incorporates a 10-bit Analog-to-Digital Converter (ADC) with up to 16 input channels, allowing for precise monitoring of multiple analog signals. Furthermore, it features two analog comparators for quick and efficient real-time signal comparison. For timing and control applications, the device is outfitted with multiple timers, including 4x 8-bit timers and 3x 16-bit timers, and 5x PWM modules for precise control of motors, LEDs, and other actuators.
Power management is a critical strength. The microcontroller supports multiple low-power modes, including Idle and Sleep modes, which drastically reduce power consumption. Its operating voltage range of 2.0V to 5.5V makes it suitable for both battery-powered and line-powered designs. The "PT" suffix denotes its 80-pin TQFP package, which offers a compact form factor suitable for high-density PCB designs.
ICGOODFIND: The PIC18F86J15-I/PT is a highly integrated and powerful 8-bit microcontroller. Its combination of a high-speed CPU, extensive memory, a critical CAN bus interface, and rich analog and digital peripherals makes it an outstanding choice for developers building connected, real-time control systems that demand reliability and comprehensive functionality.
