DS1845 BLOCK DIAGRAM Figure 1
Up to eight DS1845s can be installed on a single 2-wire bus. Access to an individual device is achieved
by using a device address that is determined by the logic levels of address pins A0 though A2.
Additionally, the DS1845 will operate from 3 volt or 5 volt supplies.
Three package options are
available: Flip Chip Package, 16-ball STPBGA and 14-pin TSSOP.
PIN DESCRIPTIONS
VCC - Power Supply Terminal. The DS1845 will support supply voltages ranging from +2.7 to +5.5 volts.
GND - Ground Terminal.
SDA - 2-wire serial data interface. The serial data pin is for serial data transfer to and from the DS1845.
The pin is open drain and may be wire-ORed with other open drain or open collector interfaces.
SCL - 2-wire serial clock interface. The serial clock input is used to clock data into the DS1845 on rising
edges and clock data out on falling edges.
WP - Write Protect. Write Protect must be connected to GND before either the data in memory or
potentiometer wiper settings may be changed. Write Protect is pulled high internally and must be either
left open or connected to VCC if write protection is desired.
A0, A1, A2 - Address Inputs. These input pins specify the address of the device when used in a multi-
dropped configuration. Up to eight individual DS1845s may be addressed on a single 2-wire bus.
