MCP2200
USB 2.0 to UART Protocol Converter with GPIO
Features
Universal Serial Bus (USB)
• Supports full-speed USB (12 Mb/s)
• Implements USB protocol composite device:
- Communication Device Class (CDC) for
communications and configuration
- Human Interface Device (HID) for I/O control
• 128-byte buffer to handle data throughput at any
UART baud rate:
- 64-byte transmit
- 64-byte receive
• Fully configurable VID and PID assignments, and
string descriptors
• Bus powered or self-powered
• USB 2.0 Compliant: TID 40001150
USB Driver and Software Support
• Uses standard Windows
®
drivers for Virtual Com
Port (VCP): Windows XP (SP2 or later), Vista, 7
• Configuration utility for initial configuration
Universal Asynchronous Receiver/Transmitter
(UART)
• Responds to
SET LINE CODING
commands to
dynamically change baud rates
• Supports baud rates: 300-1000k
• Hardware flow control
• UART signal polarity option
