1. System Overview
The CP2120 is a highly-integrated SPI-to-I2C Bridge Controller with an SPI interface that provides a simple and
reliable method for communicating with I2C devices. The CP2120 includes a 4-wire serial peripheral interface
(SPI), a serial I2C interface, 256 byte data buffers, an internal oscillator, eight input/output port pins, and one pin
configurable as an edge-triggered interrupt source in a compact 4x4 package. No external components other than
pull-up resisters on the I2C pins are required. The SPI Master controls the CP2120 across the SPI interface using
a command set that governs all CP2120 configuration and operation.

Note: Stresses above the absolute maximum ratings may cause permanent device damage. This is a stress rating only, and
functional operation of the devices at any conditions equal to or greater than those indicated in the operational listings
of this specification are not implied. Exposure to maximum rating conditions for extended periods may affect device
reliability.
