Microchip PIC18F2550-I/SO 8-Bit Flash USB Microcontroller SOIC28

The Microchip PIC18F2550-I/SO is an 8-bit flash USB microcontroller operating at up to 48 MHz in a 28-pin SOIC package.

It is built on the PIC18 core and features nanoWatt technology, which suits low-power and connectivity applications. Its serial interfaces include full speed FS-USB at 12 Mbps, I²C, SPI at up to 10 Mbps, and an asynchronous, LIN-capable EUSART.

Overview

Large amounts of RAM for buffering and enhanced flash program memory support embedded control and monitoring applications that require periodic connection to a personal computer via USB for data upload, download or firmware updates. The device is also mostly software and hardware compatible with the PIC16C745 low-speed USB OTP devices, and it introduces design enhancements aimed at high-performance and power-sensitive applications.

Key Features

• Supports low speed (1.5 Mbps) and full speed (12 Mbps) USB
• Supports control, interrupt, isochronous and bulk transfers
• Supports up to 32 endpoints (16 bidirectional)
