DS1075
HARDWARE
The hardware configuration is shown in the diagram. A bus master is used to read and write data to the
DS1075’s internal registers. The bus master may have either an open-drain or TTL-type architecture.
Figure 11
Programming mode is entered by simply powering up the DS1075 with a pull-up of approximately 5KW.
This will pull the IN/OUT pin above V
on power-up and initiate the programming mode, causing the
IH
DS1075 to internally release the IN/OUT pin (after t
), and allow the pull-up resistor to pull the pin to
POR
the supply rail and await the Master Tx Reset pulse (see diagram).
NOTE:
To ensure normal operation any external pull-up applied to IN/OUT must be greater than 20KW in value.
This will cause the IN/OUT pin to remain below V
on power-up, resulting in normal operation at the
IH
end of t
.
