1. Overview
The S5U1C31001L1200 (Bridge Board Ver. 2) is an adapter board which is inserted between general-purpose
debug probe (e.g. IAR I-jet or SEGGER J-Link) and a target board when debugging an S1C13 Family MCU.
1.1 Function
Outputs and controls V
PP
voltage (+7.5 V).
Su3 V and +5 V power voltages.
Passes control and data signals between the debug probe and the target board.
The flash memory embedded in the S1C31 Family MCUs requires a +7.5 V flash programming power supply (V
PP
)
for high-speed programming with user program/data. This board generates the V
PP
by boosting the 5 V power
voltage supplied by the debug probe
(*1)
and supplies it to the target board. The V
PP
output is controlled using the
ENVPP signal output from the S1C31 Family MCU
(*2)
.
When using the power voltage booster
(*3)
included in the S1C31 Family MCU, set JP2 on this board to open (OFF)
so that V
PP
will not be supplied to the target board from this board.
This board uses the +5 V from the debug probe for the +5 V power output to the target board. The +3 V power for
the target board is generated using the step-down regulator on this board from the +5 V. These power voltages
should only be used within the maximum allowable current of the debug probe.
(*1) 5 V to the external power supply connector J3 (see Figure 3.1) when using a debug probe that has no +5 V supply (e.g.
uLink).
(*2) This function is required only in debug mode. The ENVPP pin can be used for the original functions, however, make sure that
this does not affect the external circuits.
It is not necessary to use this board when using the MCU's power voltage booster.
(*3) For more information, refer to the technical manual for the S1C31 Family MCU model to be used.
