MSP430FR4133 LaunchPad™ Development Kit (MSP ‑ EXP430FR4133)
2.2.2 eZ-FET Onboard Emulator With EnergyTrace™ Technology
To keep development easy and cost effective, TI's LaunchPad Development Kits integrate an onboard
emulator, which eliminates the need for expensive programmers. The MSP-EXP430FR4133 has the eZ-
FET emulator (see Figure 5), which is a simple and low-cost debugger that supports all MSP430 device
derivatives.

The MSP-EXP430FR4133 LaunchPad features EnergyTrace technology but does not have support for
EnergyTrace++™ technology. The EnergyTrace functionality varies across the MSP portfolio (see
Table 1).

The eZ-FET also provides a "backchannel" UART-over-USB connection with the host, which can be very
useful during debugging and for easy communication with a PC. The provided UART supports hardware
flow control (RTS and CTS), although by default these signals are not connected to the target.
The dotted line through J101 shown in Figure 5 divides the eZ-FET emulator from the target area. The
signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. More
details on the isolation jumper block are in Section 2.2.3.
The eZ-FET hardware can be found in the schematics in Section 6 and in the accompanying MSP-
EXP430FR4133 Hardware Design Files. The software and more information about the debugger can be
found on the eZ-FET lite wiki.
