eZ-FET and eZ-FET Lite Onboard Emulation

The eZ-FET and eZ-FET Lite are powerful onboard flash emulation debug probes for application
development on MSP430 microcontrollers (see

Figure 30

). The eZ-FET and eZ-FET Lite onboard

emulation are the successors of the legacy eZ430.

Both eZ-FETs provide a USB interface to program and debug the MSP430 devices in-system through the
pin-saving Spy-Bi-Wire (2-wire JTAG) protocol. Furthermore, the USB interface can be used for
backchannel UART communication.

Both development tools support development with all MSP430 devices. They are designed as onboard
emulation that is available on several LaunchPad kits. (Only MSP430 devices that implement the SBW2
protocol are supported.)
