UCD3138128A Highly Integrated Digital Controller

Texas Instruments UCD3138128A Highly Integrated Digital Controller offers superior levels of integration and performance in a single chip solution. The UCD3138128A offers 128kB of program flash memory in comparison to 32kB in UCD3138A. This device provides additional options for communication such as SPI and a second I2C/PMBus port. The availability of program Flash memory in multiple 32kB banks enables designers to implement dual images of firmware in the device. This feature provides the option to execute from either of the banks using appropriate algorithms. This creates the unique opportunity for the processor to load a new program and subsequently execute that program without interrupting power delivery. This feature also allows the end user to add new features to the power supply in the field while eliminating any downtime required to load the new program.
