12 / 74 page ![]() ASX340CS_DS Rev. F Pub. 6/15 EN 12 ©Semiconductor Components Industries, LLC, 2015. ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor Pin Descriptions and Assignments Pin Assignments Pin 1 is not populated with a ball. That allows the device to be identified by an additional marking.

Must always be driven to high via a pull-up resistor in the range of 1.5 to 4.7 k. SDATA High impedance High impedance Input/Output. Must always be driven to high via a pull-up resistor in the range of 1.5 to 4.7 k. SADDR N/A N/A Input. Must be permanently tied to VDD_IO or GND. SPI_SCLK High impedance. Driven, logic 0 Output. Output enable is R0x0032[13]. SPI_SDI Internal pull-up enabled. Internal pull-up enabled Input. Internal pull-up is permanently enabled. SPI_SDO High impedance Driven, logic 0 Output enable is R0x0032[13]. SPI_CS_N High impedance Driven, logic 1 Output enable is R0x0032[13]. FRAME_VALID High impedance High impedance Input/Output. This interface disabled by default. Input buffers (used for GPIO function) powered down by default, so these pins can be left unconnected (floating). After reset, these pins are powered up, sampled, then powered down again as part of the auto- configuration mechanism. See Note 2. LINE_VALID |
