The Microchip PIC18F87J10T-I/PT represents a high-performance, 8-bit microcontroller within the expansive PIC18 family, engineered for demanding embedded control applications. This device integrates a powerful suite of peripherals, substantial memory, and robust connectivity options into an 80-pin TQFP package, making it a versatile solution for complex industrial, automotive, and consumer systems.

At the core of this microcontroller lies an enhanced PIC18 architecture with a 16-bit instruction set and an 8-bit data path. Operating at up to 40 MHz with an external oscillator, it achieves a performance level of 10 MIPS, providing the necessary computational throughput for sophisticated real-time control tasks. A key feature enhancing its reliability in noisy environments is the nanoWatt Technology, which offers advanced power management modes, including multiple Idle and Sleep states, allowing for significant power reduction in battery-sensitive applications.

Memory resources are substantial. The PIC18F87J10T boasts 128 KB of self-read/write capable Flash program memory and 3,792 bytes of RAM. This ample space allows for the storage of large application code and efficient handling of complex data variables. Furthermore, it includes 1,024 bytes of data EEPROM, providing critical non-volatile storage for parameters that must be retained after a power cycle.

Its peripheral set is exceptionally rich and designed for connectivity. 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 equipped with several serial interfaces: EUSART modules (for RS-232/485), SPI, and I2C ports, facilitating easy communication with a vast ecosystem of sensors, memories, and other peripherals. Specialized peripherals include ECAN (Enhanced Controller Area Network) 2.0B for robust automotive and industrial network communication and a hardware PWM module for precise motor control and power regulation.

The inclusion of DMA (Direct Memory Access) for the ADC and SPI modules offloads data transfer tasks from the CPU, significantly increasing system efficiency and reducing power consumption. The device operates over an extensive voltage range of 2.0V to 5.5V and across a wide industrial temperature range (-40°C to +85°C), ensuring stable operation in harsh environmental conditions.
