PIC18F86J11-I/PT

PIC18F86J11-I/PT is an 8‑bit Microchip PIC microcontroller in the PIC18F86J11 family. The -I/PT suffix indicates an Industrial temperature rating (-40°C to 85°C) and Tape‑and‑Reel packaging (for automated assembly).
Key points:
- Core and speed: 8‑bit PIC core, up to 40 MHz clock (~10 MIPS).
- Memory: on‑chip Flash (tens of KB) for program storage and RAM (a few KB), with optional EEPROM.
- Peripherals: 10‑bit ADC, multiple 8/16‑bit timers, CCP/PWM, SPI/I2C (MSSP), EUSART, basic analog comparators.
- I/O and peripherals: general-purpose I/O ports with built‑in analog/digital capabilities.
- Power and sleep: operates around 2.0–5.5 V; sleep/idle power modes for low power.
- Tools: supported by MPLAB X IDE and XC8 compiler; debugging with common Microchip debuggers.
- Applications: small to mid‑range embedded control, sensors, motor control, automation.
In short, a versatile PIC18F MCU for industrial‑temp, tape‑packaged applications.
