• Manufacturer Part Number: CYIL1SM4000AA-GWCES
• Description: 4 Megapixel CMOS Image Sensor
• Manufacturer: Cypress Semiconductor Corp.

Serial-Parallel-Interface (SPI)
The SPI is required to upload the different modes.
Table 15. SPI parameters
When all zeros are loaded into the SPI, the sensor starts at pixel
0,0. The scanning is from left to right and from top to bottom.
There is no sub sampling or voltage averaging and only one
output is used. The DAC has the lowest level at its output.
