PIC18F86J94-I/PT

PIC18F86J94-I/PT is an 8‑bit Microchip PIC microcontroller in the PIC18F86J94 family, intended for general embedded control with enhanced peripherals. It features a Harvard architecture PIC18 core, Flash program memory, RAM and EEPROM, and a rich set of peripherals including multiple timers, CCP/PWM, USART (and SPI/I2C), an on‑chip ADC, comparators, and I/O ports. The device operates over an industrial temperature range (-40°C to 85°C) and is offered in a Plastic Tape & Reel package, as indicated by -PT; the -I suffix denotes industrial grade. Typical applications include sensors, motor control, instrumentation, and consumer/industrial controllers requiring moderate speed and integrated peripherals. Development uses Microchip MPLAB X IDE with XC8/XC16 compilers; debugging tools include ICD/real‑time debuggers. For exact memory size, peripheral counts, ADC channels, oscillator options, and package pins, consult the datasheet and package drawings. In short: a capable 8‑bit MCU for embedded control with a broad peripheral set and Microchip development ecosystem.
