USB-232
Driver-free
USB to asynchronous serial UART interface
USB-232 is a single chip USB to asynchronous
serial interface. It greatly simplifies the connection of electronic devices to
personal computer. In addition to the standard signal lines, additional control
lines have custom-defined functionality.
USB-232 uses the Human Interface Device (HID) USB profile.
It does not require USB drivers and so is immediately plug-and-play with present
and future Windows, Linux and Mac operating systems.
USB-232 is firmware for the PIC18LF2450 and PIC18F14K50 microcontrollers. It is available pre-programmed as a 28-pin DIL package (2450)
and a 20 pin SSOP package (14K50).
• True HID plug and play - No drivers required
• No Vendor ID / Product ID registration required
• Baud rates selectable from 110 to 460K
• 11 invertible auxiliary I/O pins
Competitive positioning
The USB-232 strengths compared to competitors are:
• Low price
• No driver installation required
• No virtual COM port
- software locates HID devices directly
• No Vendor ID / Product ID registration costs
Not suitable for retrofitting to COM port legacy applications.
