DS1669S-10

The purpose of the EEPROM memory cell array in maintaining the wiper position of the DS1669 Dallastat in the absence of power is to store the last recorded wiper setting. This feature allows the Dallastat to retain the wiper position even when power is not applied. The EEPROM memory cells are updated periodically by the input multiplexer to ensure reliability, durability, and performance. The update operation is transparent to the user, and any changes made to the wiper setting after power is applied will be stored after a 2-second delay. The EEPROM memory cells can withstand more than 50,000 writes, ensuring long-term functionality of the Dallastat.

The standard resistive range options for the DS1669 Dallastat mentioned in the document are 10 kΩ, 50 kΩ, and 100 kΩ.

The DS1669 Dallastat provides 64 possible uniform tap points over the entire resistive range.
