3 . Chip Overview
GX1821 can be used as an independent thermostat with user programmable trigger temperature points, or as an 8-bit temperature sensor with a single bus digital interface. The temperature point triggered by the thermostat is stored in non-volatile memory, so the GX1821 unit can be programmed before being connected to the system to achieve true independent operation. The working temperature range of GX1821 is -55 ℃ to+125 ℃, with an accuracy of ± 1 ℃ within the range of 0 ℃ to+85 ℃. Communication with GX1821 is achieved through the drain DQ pin; This pin is also used as a thermostat output.
