安森美车规级1080P图像传感器AR0231手册
资料介绍
AR0231AT7C00XUEA0-DRBR（RGB滤光）
安森美半导体推出采用突破性减少LED闪烁 (LFM)技术的新的230万像素CMOS图像传感器样品AR0231AT，为汽车先进驾驶辅助系统(ADAS)应用确立了一个新基准。新器件能捕获1080p高动态范围(HDR)视频，还具备支持汽车安全完整性等级B(ASIL B)的特性。
LFM技术(专利申请中)消除交通信号灯和汽车LED照明的高频LED闪烁，令交通信号阅读算法能于所有光照条件下工作。AR0231AT具有1/2.7英寸(6.82 mm)光学格式和1928(水平) x 1208(垂直)有源像素阵列。它采用最新的3.0微米背照式(BSI)像素及安森美半导体的DR-Pix™技术，提供双转换增益以在所有光照条件下提升性能。它以线性、HDR或LFM模式捕获图像，并提供模式间的帧到帧情境切换。
AR0231AT提供达4重曝光的HDR，以出色的噪声性能捕获超过120dB的动态范围。AR0231AT能同步支持多个摄相机，以易于在汽车应用中实现多个传感器节点，和通过一个简单的双线串行接口实现用户可编程性。它还有多个数据接口，包括MIPI(移动产业处理器接口)、并行和HiSPi(高速串行像素接口)。其它关键特性还包括可选自动化或用户控制的黑电平控制，支持扩频时钟输入和提供多色滤波阵列选择。
封装和现状：AR0231AT采用11 mm x 10 mm iBGA-121封装，现提供工程样品。工作温度范围为-40℃至105℃(环境温度)，将完全通过AEC-Q100认证。

Advance Information
AR0231AT 1/2.7-inch 2.3 Mp
Digital Image Sensor
Description
The AR0231AT from ON Semiconductor is a 1/2.7−inch CMOS
digital image sensor with a 1928(H) × 1208 (V) active−pixel array. It
captures images in either linear, high dynamic range, or LFM modes,
with a rolling−shutter readout. The LFM mode eliminates high
frequency LED flicker in the image allowing Traffic Sign Reading
(TSR) algorithms to operate in all lighting conditions. It includes
sophisticated camera functions such as in−pixel binning, windowing
and both video and single frame modes. It is designed for both low
light and high dynamic range scene performance, with sensor fault
detection features that can enable ASIL B compliance for the camera
system. It is programmable through a simple two−wire serial interface.
The AR0231AT produces extraordinarily clear, sharp digital pictures,
and its ability to capture both continuous video and single frames
makes it the perfect choice for a wide range of applications, including
automotive ADAS, automotive scene viewing, and 1080p HDR video.
