FUNCTIONAL DESCRIPTION

The MCP2210 device is a USB-to-SPI Master

converter

which

enables

USB

connectivity

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 Table 1-1 and

Section 1.6 “GP Module” for details about the pin

functions.
