With the 7900 Series emulator system, the internal flash ROM of the emulator MCU is used as an
emulation memory.

As write/erase iterations to the internal ROM are limited, it is necessary to replace the MCU board
(M379xxTx-PRBM) depending on its life span.

How to replace the MCU board is shown in Figure 3.8.

Figure 3.8 Removing MCU board M379xxTx-PRBM

(1) Unscrew the 4 screws of the M379xxTx-PRB.

(2) Remove the M379xxTx-PRBM from the M379xxTx-

PRB. In this time, lift off the M379xxTx-PRBM
horizontally. Otherwise, the connector may cause a
break.

CAUTION

When Connecting Pod Probe:

• Always shut OFF power when connecting the pod probe. The power ON state could

destroy internal circuits.

• The insertion/removal iterations of the connector of the pod probe are limited. Check

your pod probe's user's manual.

• For some types of the pod probe, the method of connection is different. Check your

pod probe's user's manual.
