Description
The IMX334LQR-C is a diagonal 8.86 mm (Type 1/1.8) CMOS active pixel type solid-state image sensor with a
square pixel array and 8.42 M effective pixels. This chip operates with analog 2.9 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.
(Applications: Surveillance cameras, FA cameras, Industrial cameras)

Register Write and Read (I
2
C)
This sensor corresponds to four reed modes and the two write modes.
Single Read from Random Location
The sensor has an index function that indicates which address it is focusing on. In reading the data at an optional
single address, the Master must set the index value to the address to be read. For this purpose it performs dummy
write operation up to the register address. The upper level of the figure below shows the sensor internal index
value, and the lower level of the figure shows the SDA I/O data flow. The Master sets the sensor index value to M
by designating the sensor slave address with a write request, then designating the address (M). Then, the Master
generates the start condition. The Start Condition is generated without generating the Stop Condition, so it
becomes the Repeated Start Condition. Next, when the Master sends the slave address with a read request, the
sensor outputs an Acknowledge immediately followed by the index address data on SDA. After the Master
receives the data, it generates a Negative Acknowledge and the Stop Condition to end the communication
Single Read from Current Location
After the slave address is transmitted by a write request, that address is designated by the next communication
and the index holds that value. In addition, when data read/write is performed, the index is incremented by the
subsequent Acknowledge/Negative Acknowledge timing. When the index value is known to indicate the address
to be read, sending the slave address with a read request allows the data to be read immediately after
Acknowledge. After receiving the data, the Master generates a Negative Acknowledge and the Stop Condition to
end the communication, but the index value is incremented, so the data at the next address can be read by
sending the slave address with a read request.
