ShenZhen Mingjiada Electronics Sells New Broadcom Automotive Ethernet PHY BCM89083A0BFBG Automotive Camera MCU with Integrated Image Processing and Ethernet Streaming Pipeline

Overview

The BCM89083A0BFBG is a fully integrated BroadR-Reach® camera endpoint microcontroller for automotive rear-view camera and side-view camera applications.The Arm Cortex-M7 supports low-latency interrupt processing through the use of a Real-Time Operating System (RTOS), runs the Ethernet Audio/Video Broadcasting (AVB) stack, and handles a variety of peripherals’ housekeeping tasks. An enhanced cache architecture improves system performance.

The CMOS image sensor interface supports a dual-channel MIPI CSI-2 interface. the ISP supports black level adjustment, lens shading correction, 2D adaptive noise filtering, defective pixel compensation, white balance adjustment, colour crosstalk compensation, edge sharpening, demosaicing, colour correction and gamma correction, pseudo-colour suppression, hue and saturation control, and adaptive local tone mapping in hardware pipeline.

The display controllers can directly drive dual- or quad-channel OpenLDI and MIPI DSI displays and can connect to external LVDS serialisers. A graphics plane overlay with alpha blending can overlay driving tracks, gauges, or other visual elements before the video is encoded and streamed over BroadR-Reach Ethernet.

The device also supports the IEEE 802.1as and IEEE 802.1Q AVB bridge standards for clock synchronisation and video streaming. the BCM89083 integrates multiple I/O controllers including SPI, QSPI, I2S/TDM, I2C, UART/LIN, PDM, and GPIOs. the BCM89083 also includes on-chip switching regulators and FETs to simplify power design. The BCM89083 also includes on-chip switching regulators and FETs to simplify power supply design.
