MCP2200
1.0
FUNCTIONAL DESCRIPTION
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.
The MCP2200 has eight general purpose input/output
pins. Four pins have alternate functions to indicate
USB and communication status. See
and
for details about the pin
functions.
