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 Table 1-1 and

Section 1.6 “GPIO Module”

for details about the pin

functions.
