The Microchip MCP2210 chip is an easy way to go from USB to SPI with one, dedicated, chip. Microchip also features an evaluation kit and breakout module for the MCP2210.

No need to program the chip. Everything you need is already on there.

Considering that this is very likely a pre-programmed dedicated chip I expect to find a 18F14K50 underneath just like the MCP2200 USB to UART conversion chip, see here and here. With the upcoming PCB design where an ISP header will be added this will be easy to verify with a PicKit.

 

In case you want to make your own breakout board and play with the chip please read on.

The schematic is from the Microchip evaluation board. I removed the 3.3V power and ISP header to boil down to the bare minimum board. The schemati now looks like this, note that the chip says MCP2200 in my schematic since there was no Eagle MCP2210 equivalent available. Luckily both are pin compatible so even though it says MCP2200 it will work jut fine for the MCP2210.
