The eZ430-RF emulator board includes a USB connector and the circuits required to interface the development IDE software and USB port to the MSP430 target. Some key components on this emulator include a TUSB3410 for the USB interface, a TPS77301 for 3.3V regulation, and an EEPROM used for non-volatile information. The eZ430-RF provides a regulated 3.3V to the eZ430-RF2500T target board. Also, on the backside of the eZ430U, a MSP430F169 is used to accelerate the interface to the target. Additionally, ESD protection components are also used.
