概述
Description
The PIC18F86J90T-I/PT is Microchip’s mid‑range PIC18 8‑bit microcontroller featuring a built‑in USB 2.0 full‑speed interface. It uses the PIC18 core and provides on‑chip flash program memory, data RAM, and optional EEPROM. Peripherals typically include multiple timers, CCP/PWM channels, ADC, USART/SPI/I2C, and a USB device controller, plus DMA/CRC capabilities and general I/O. It supports industrial-temperature operation and comes in various packages (including PT). It targets USB‑enabled embedded applications such as data logging, sensing, motor control, and human‑machine interfaces. Development is via MPLAB X IDE with the XC8/C18 compilers and Microchip USB libraries and middleware. For exact specs (memory size, USB speeds, package options), consult the datasheet and product brief.
