1.
CP2400/1/2/3 devices are fixed function LCD drivers that can also be used for expanding GPIO, timekeeping, and
increasing available system RAM by up to 256 bytes. The device is controlled using direct and indirect internal
registers accessible through the 4-wire SPI or 2-wire SMBus interface. All digital pins on the device are 5 V
tolerant.
