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.
