Overview

The PIC18F4550-I/P is a high-performance 8-bit microcontroller featuring a built-in USB 2.0 compliant interface capable of Full Speed (12 Mb/s) and Low Speed (1.5 Mb/s) operation. It comes in a 40-pin PDIP package, offering 32KB of Flash memory and 2KB of RAM, making it a popular choice for legacy hardware interfacing and DIY peripheral development.

Why Choose This Part

The integrated USB engine includes a dedicated 1KB Dual Access RAM and an on-chip voltage regulator, significantly reducing external component count for bus-powered designs. It also features a hardware 8x8 multiplier for faster math execution and nanoWatt technology for improved power management in idle and sleep modes.

Applications

Custom USB Peripherals
Designing HID-class devices like custom keyboards, mice, or game controllers using the integrated USB transceiver.
Legacy Industrial Interfacing
Utilizing the Streaming Parallel Port (SPP) to move data between external peripherals and the USB port.
Educational Prototyping
Developing embedded USB firmware on breadboards thanks to the easy-to-solder 40-pin PDIP form factor.

Getting Started

Develop using the Microchip MPLAB X IDE and the XC8 compiler. Hardware programming and debugging require a tool like the PICkit 4 or MPLAB ICD 4, which connects to the device via the In-Circuit Serial Programming (ICSP) interface.
