Detailed Description of Hardware
Santa Cruz is size optimized to meet industrial control and automation light-sensing applications where space is limited. The
case sizes of the discrete components were carefully selected to ensure they meet the harsh conditions in an industrial
environment.
The MAX14821 IO-Link device transceiver is IO-Link version 1.1/1.0 physical layer compliant with integrated 3.3V/5V linear
regulators, configurable outputs (push-pull, pnp or npn), reverse-polarity/short-circuit protection, extensive fault monitoring all in a
tiny 2.5mm x 2.5mm WLP package.
The ambient light (clear), red, green, blue, infrared, and temperature data can be
read continuously from the MAX44008 through an I
2
C interface. The light sensor
has six integrated sensors with each sensor having its own on-chip dedicated
PGA and 14-bit ADC inside a miniature optical 2mm x 2mm OTDFN package.
Receiving light at a right angle to the board edge is important to allow compatibility
