Abstract
An integrated circuit comprises a first microcontroller unit located on a first die. The first microcontroller unit includes a first processing core for providing a parallel stream of data. A second microcontroller unit is located on a second die and includes a second processing core for receiving the parallel stream of data. Voltage isolation circuitry transmits data from the parallel data stream between the first microcontroller and the second microcontroller in a serial data stream and provides galvanic isolation between the first microcontroller unit and the second microcontroller unit.
