Confidential HV7131R General Description HV7131R is a highly integrated single chip CMOS color image sensor implemented by proprietary MagnaChip 0.30um CMOS sensor process realizing high sensitivity and wide dynamic range. Total pixel array size is 656x502, and 640x480 pixels are active. Each active pixel composed of 4 transistors, it has a micro-lens to enhance sensitivity. and it converts photon energy to analog pixel voltage. On-chip 10-bit Analog to Digital Converter (ADC) are configured to digitize analog pixel voltage, and on-chip Correlated Double Sampling (CDS) scheme reduces Fixed Pattern Noise (FPN) dramatically. Auto Black Level Compensation (ABLC) is using light blocking shield pixels which is placed top and bottom at core pixel to measure the black level and compensation.

HV7131R Confidential Functional Description Pixel Architecture Pixel architecture is a 4-transistor NMOS pixel design. The additional use of a dedicated transfer transistor in the architecture reduces most of reset level noise so that fixed pattern noise is not visible. Furthermore, micro-lens is placed upon each pixel in order to increase fill factor so that high pixel sensitivity is achieved. Sensor Imaging Operation Imaging operation is implemented by the offset mechanism of integration domain and scan domain(rolling shutter scheme). First integration plane is initiated, and after the programmed integration time is elapsed, scan plane is initiated, then image data start being produced.

HV7131R Confidential The serial bus interface consists of the SDA(serial data) and SCK(serial clock) pins. HV7131GR sensor can operate only as a slave. The SCK only controls the serial interface. However, MCLK should be supplied and RESET should be high signal during controlling the serial interface. The Start condition is that logic transition (High to Low) on the SDA pin while the SCK pin is at high. The Stop condition is that logic transition (Low to High) on the SDA pin while the SCK pin is at high. To generate Acknowledge signal, the Sensor drives the SDA low when the SCK is high. Every byte consists of 8 bits. Each byte transferred on the bus must be followed by an Acknowledge. The most significant bit of the byte should always be transmitted first.

If you set ENB pin to low, sensor goes to power down. Though sensor remains power down, you can program the registers by above IIC protocol. After ENB is changed to high, the registers that you set in power down are newly updated. If you want software power down with ENB pin high, set sleep mode in SCTRB(02H)register. ENB VSYNC HSYNC DATA[9:0] VCLK RESETB Timing RESETB pin initializes the registers to default value. When RESETB pin is low, initialization is done. HV7131GR is automatically reset the chip when power on. We recommend to initialize the registers by using RESETB pin. TR: RESETB valid minimum time: 10 MCLK periods.
