• Manufacturer: Microchip Technology

1.0
The MCP2200 is a USB-to-UART serial converter
which enables USB connectivity in applications that
have a UART interface. The device reduces external
components by integrating the USB termination
resistors. The MCP2200 also has 256 bytes of
integrated user EEPROM.

Standard Function
The MCP2200 has eight general purpose input/output
pins. Four pins have alternate functions to indicate
USB and communication status. See
Section 1.6 “GPIO Module” for details about the pin
functions.
