The IMX225LQR is a diagonal 6.09 mm (Type 1/3) CMOS active pixel type solid-state image sensor with a square pixel array and 1.27 M effective pixels. This chip operates with analog 3.3 V, digital 1.2 V, and interface 1.8 V triple power supply, and has low power consumption. High sensitivity, low dark current and no smear are achieved through the adoption of R, G and B primary color mosaic filters. This chip features an electronic shutter with variable charge-integration time.

This sensor has a total of 1020 bytes (255 × 4) of registers, composed of registers with addresses 00h to FEh that correspond to Chip ID = 02h (write mode) / 82h (read mode), Chip ID = 03h (write mode) / 83h (read mode), Chip ID = 04h (write mode) / 84h (read mode), and Chip ID = 05h (write mode) / 85h (read mode). Use the initial values for empty address. Some registers must be change from the initial values, so the sensor control side should be capable of setting 1020 bytes.

The values must be changed from the default value, so initial setting after reset is required after power-on. There are two different register reflection timing. Values are reflected immediately after writing to register noted as “Immediately”, or at the frame reflection register reflection timing described in the item of “Register Communication Timing” in the section of “Setting Registers with Serial Communication” for registers noted as “V” in the Reflection timing column of the Register Map. For the immediate reflection registers other than belows, set them in sensor standby state.

Do not perform communication to addresses not listed in the Register Map. Doing so may result in operation errors.

However, other registers that requires communication to address not listed above may be added, so addresses up to FEh should be supported for CID = 02h, 03h, 04h and 05h. (In I2C communication, address; 3000h to 30FEh, 3100h to 31FEh, 3200h to 32FEh, 3300h to 33FEh) For the register that is writing " * " to the setting value in description (Indicated by red letter), change the value from the default value after the reset.
