embedded micro-controller with the built-in statistics of AE / AWB. The flexible architecture includes the mask ROM,
internal RAM and external serial-flash which can store the customized codes and parameters.
There are 3 built-in regulators and no needs of external oscillator, these features make it able to further save BOM
and PCB area. The SN9C2805A is the best choice for the compact modern electronic product design.
