CP2120
1. System Overview
The CP2120 is a highly-integrated SPI-to-I
reliable method for communicating with I
(SPI), a serial I
configurable as an edge-triggered interrupt source in a compact 4x4 package. No external components other than
pull-up resisters on the I
a command set that governs all CP2120 configuration and operation.
