Product overview
Description
The VB1740 and VD1740 are 2.7 MP image sensors with both rolling and global shutter modes.
In rolling shutter mode, the VB1740 and VD1740 produce a single HDR color frame output through the MIPI CSI-2 interface. This is achieved by combining a short and long exposure. In addition, the user can activate a function that converts the RGB NIR pattern to an RGGB format. Such a format is compatible with any standard automotive ECU (electronic control unit).
In global shutter mode, the RGB pixels upscale the NIR image to full resolution. This innovative use of the NIR information is achieved thanks to the independent exposition of the NIR and RGB pixels.
The sensor captures up to 60 frames per second in a 1920 x 1432 resolution format. The device is fully configurable through the I²C serial interface. It also provides flexible frame-to-frame configuration changes via the use of programmable contexts. Up to four contexts can be sequenced in a versatile loop of up to 32 elements.
The sensor is designed as a SEOOC (safety element out of context). It is compliant with ISO26262 standards and ASIL-B safety levels.
The VB1740 and VD1740 are designed with a full set of cybersecurity features.
