Texas Instruments UCD3138064RGCT

Description
The UCD3138064 is a highly integrated digital controller for isolated power with 64-kB program flash memory. It is a derivative of the UCD3138 family with 2-32 kB program flash memory banks, allowing for execution from one bank while programming another. This capability enables firmware updates without shutting down the power supply.
