FUNCTIONAL DESCRIPTION
The MCP2210 device is a USB-to-SPI Master
converter which enables USB connectivity in
applications that have an SPI interface. The device
reduces external components by integrating the USB
termination resistors. 
The MCP2210 also has 256 bytes of integrated user
EEPROM.
The MCP2210 has nine general purpose input/output
pins. Seven pins have alternate functions to indicate
USB and communication status. See 
 and
 for details about the pin
functions.
