Description
The PIC18F46J11-I/PT is a 8-bit microcontroller from Microchip’s PIC18F family, featuring a 16 MHz internal oscillator, 64 KB Flash, 3.8 KB RAM, and 1 KB EEPROM. It operates at 2.0V–5.5V, making it suitable for low-power applications.
Key features include:
- Enhanced mid-range core with 16-bit instructions
- 36 I/O pins with 5V tolerance
- Peripheral modules: 10-bit ADC, USART, SPI, I²C, PWM
- Low-power modes (Sleep, Idle)
The -I/PT suffix indicates an industrial temperature range (-40°C to +85°C) and a 44-pin TQFP package. Ideal for embedded control, automation, and IoT applications, it balances performance and power efficiency.
For development, use MPLAB X IDE with PICkit or ICD programmers.
