PIC18F86J90T-I/PT

An introduction to PIC18F86J90T-I/PT:
- It is an 8‑bit PIC microcontroller from Microchip’s PIC18F86J90 family, designed for embedded control tasks that require a balance of speed, peripherals, and cost. It combines a high‑performance PIC18 core with on‑chip memory and peripherals, making it suitable for consumer, automotive, and industrial applications.
- Core features (typical): on‑chip program flash memory and RAM; multiple I/O pins; timers/counters; ADC with multiple channels; capture/compare/PWM; multiple serial communication blocks (USART, SPI, I2C); interrupt controller with priority levels; watchdog timer; various oscillator options; power management. Some devices in the 86J90 family may integrate USB (FS) or other high‑speed interfaces depending on the variant.
- Package and temperature: The -I suffix denotes industrial temperature range; -PT denotes Plastic package with Tape & Reel packaging.
- Why use it: compact, flexible MCU for control, sensing, and communication tasks with Microchip tooling and ecosystem.
- For exact specs, memory sizes, pin count, and USB/CAN capabilities, refer to the datasheet and family reference manual on Microchip’s website.
