The SD6500 has built-in 24 bits ADC and two-wire communication circuits.
A host computer can read and edit all the registers in the IC through the two-wire communication circuit.
The IC supports the timed measurement comparison mode. After entering this mode, the IC will turn on the host after successful data comparison. The host can also independently turn on the IC.
The IC has built-in temperature sensor, and 8 bits DAC to meet the requirements of various applications.
