MEMORY ORGANIZATION
The DS1845’s serial EEPROM is internally organized with 256 words of 1 byte each. Each word requires
an 8-bit address for random word addressing. The byte at address F9h determines the wiper setting for
potentiometer 0, which contains 100 positions. Writing values above 63h to this address sets the wiper to
its uppermost position. The byte at address F8h determines the wiper setting for potentiometer 1, which
contains 256 positions (00h to FFh). The factory default wiper position for both potentiometers is FFh.
Memory locations 00h to F7h are factory programmed to 00h. Address locations FAh though FFh are
reserved and should not be written.
DEVICE OPERATION
Clock and Data Transitions: The SDA pin is normally pulled high with an external resistor or device.
Data on the SDA pin may only change during SCL low time periods. Data changes during SCL high
periods will indicate a start or stop conditions depending on the conditions discussed below. Refer to the
timing diagram Fig 2 for further details.
Start Condition: A high-to-low transition of SDA with SCL high is a start condition which must
precede any other command. Refer to the timing diagram Fig 2 for further details.
Stop Condition: A low-to-high transition of SDA with SCL high is a stop condition. After a read
sequence, the stop command places the DS1845 into a low-power mode. Refer to the timing diagram Fig
2 for further details.
Acknowledge: All address and data byte are transmitted via a serial protocol. The DS1845 pulls the
SDA line low during the ninth clock pulse to acknowledge that it has received each word.
Standby Mode: The DS1845 features a low-power mode that is automatically enabled after power-on,
after a stop command, and after the completion of all internal operations.
