VGA 1/4-inch CIS SOC — key parametrics for the BOM
The onsemi ASX340AT3C00XPED0-DRBR is a VGA-resolution (728H x 560V active pixel array) CMOS image sensor in a 1/4-inch optical format, integrating the sensor and image processing onto a single chip (SOC). It delivers 60 frames per second at full resolution, with a pixel size of 5.6µm x 5.6µm — the relatively large pixel for a VGA sensor gives it a light-gathering advantage in low-light automotive or surveillance scenes compared to smaller-pixel VGA parts.
Supply rail and package — board-fit checklist
The core supply voltage is 1.8V, a single-rail design that simplifies the power tree — no separate analog or I/O rail needed, though the external decoupling at the package pins must stay within 0.1 µF per the reference layout to keep the pixel column noise below 1 LSB. It ships in tray packaging, which is the standard delivery format for optical sensors — the tray protects the glass lid from scratches and dust during handling and reflow.
