USB to SPI Bridge

The CP2130 is a highly-integrated USB-to-SPI bridge controller providing a simple solution for bridging a Universal Serial Bus (USB) host to a Serial Peripheral Interface (SPI) bus using a minimum of components and PCB space. The CP2130 includes a USB 2.0 full-speed controller, USB transceiver, oscillator, one-time programmable (OTP) ROM, and a SPI controller in a compact 4 mm x 4 mm QFN24 package.
