MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
MCU Flash Programming Configuration
To allow for the possibility of downloading software into the
application memory (MCU EEPROM or Flash), the 33742 is
capable of allowing (1) V
DD
to be forced by an external power
supply to 5.0 V and (2) the
RST
and the
WDOG
outputs to be
forced by external signal sources to 0 V or 5.0 V, both without
damaging the device. This allows, for example, the complete
application board to be supplied by external power supply and
external signal to be applied to the reset terminals. No functions
of the 33742 are operating.
Figure 15
illustrates a typical
configuration for the connection of programming and debugging
tools.
The V
DD
regulator has an internal pass transistor between
V
SUP
and the V
DD
output terminal. Biasing the V
DD
output
terminal with a voltage greater than V
SUP
potential will force
current through the body diode of the internal pass transistor to
the V
SUP
terminal. Therefore, V
SUP
should be left open or
forced to a value equal to or above V
DD
.
The
RST
terminal is periodically pulled LOW for t
RSTDUR
time
(device in reset mode), before being pulled to V
DD
for 350 ms
typical (device in Normal Request mode). During the time reset
is LOW, the
RST
terminal sinks 5.0 mA maximum (I
PDW
).
