2.8 In-Circuit Emulator (ICE) Adaptor
The 78M6631 firmware (stored in internal flash memory) can be updated to accommodate program
enhancements. Use the Signum ADM51 or the Teridian TFP-2 to download new firmware to the
78M6631. The supplied ICE Adaptor is required to interface the flat ribbon cable (provided with the
ADM51 or TFP-2) to the 78M6631 Evaluation Board.
Figure 3: ICE Adaptor
Figure 4 shows how to attach the ICE Adaptor to the 78M6631 Evaluation Board. Please make note of
the orientation of the ICE Adaptor as to how it attaches to the 78M6631 Evaluation Board (V3P3 ICE
Adaptor pin connects to the +V3P3 Evaluation Board pin).
Figure 4: Attaching the ICE Adaptor
Disconnect the 78M6631 Evaluation Board from live AC voltages before connecting the
ADM51 or TFP-2. An Earth ground disparity and high AC voltages are present on the
78M6631 Evaluation Board when it is connected to the AC outlet. Equipment damage
to the 78M6631, ADM51/TFP-2 and attached PC may occur when live AC voltages are
present on the 78M6631 Evaluation Board. Refer to the 78M6631 Safety Precautions
Applications Note for additional information.
It is recommended to always use the supplied flat ribbon cable. Do not use discrete wires in place of the
flat ribbon. Poor signal integrity will cause flash memory programming errors. Additional adaptors and flat
ribbon cables can be ordered through Maxim’s Teridian customer service.
Power to the 78M6631 is provided via the USB cable. Attach the USB cable during programming.
