The HVCPU board provides an I2C interface that is dedicated to communicating with Brooks devices and is not available for connecting to customer equipment. This is a high-speed serial protocol that can be daisy-chained to interconnect multiple I2C devices. For example, I2C is utilized internally in the controller to interface to a series of temperature sensors and the NVRAM. For the 2000W PrecisePower Intelligent Motor Power Supply, an I2C connection provides power supply status information to the PreciseFlex Controller and is necessary to operate this power supply in a CAT-3 compliant mode. In the past, I2C was also used to interface to legacy Brooks gripper control boards.
