Figure 2. Typical Spectral Responsivity
3 Hardware Design Considerations
Depending on the used firmware releases, there exists for AS7265x schematic two alternative
versions, named generation 1 and 2. Compared with the older generation 1, in AS7265x new
generation 2, the INT and SLV_RST1 pin are swapped on default. Note, all components for
generation 1 and 2 in firmware, software and hardware are not compatible.
The following figures show the schematics for generation 1 and 2.
