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.

Universal Serial Bus (USB)

• Supports full-speed USB (12 Mb/s)
• Human Interface Device (HID) device
• 128-byte Buffer to handle data throughput:
  • 64-byte transmit
  • 64-byte receive
• Fully configurable VID, PID assignments and string descriptors
• Bus powered (factory default) or self-powered (can be selected through special USB commands)
• USB 2.0 Compliant

USB Driver and Software Support

• Uses standard HID drivers (built-in support on Windows® XP, Vista, 7, Linux and Mac OS®)
• Configuration utility for device’s power-up configuration
• Utility for USB-SPI communication, GPIO manipulation and miscellaneous features usage

SPI Master peripheral

• Supports all four SPI modes (Mode 0, 1, 2, 3)
• Bit-rates from 1500 bps up to 12 Mbps
• Configurable delays for SPI transactions:
  • Chip Select (assert) to 1st byte of data delay
  • Data to data delay
  • Data to Chip Select (de-assert) delay
• SPI transactions lengths of up to 65535 bytes long
• Up to 9 Chip Select lines – to be used in any combination for a given SPI transaction (the chip select lines are shared between GPIOs and alternate function pins; certain GPs – up to 9 of them – can be assigned with the chip select functionality)

General Purpose Input/Output (GPIO) Pins

• Nine general purpose I/O pins

EEPROM

• 256 bytes of user EEPROM (accessible only through certain USB commands)
