GW5300(GW5310)
GENERAL DESCRIPTION
The GW5300 is an advanced Camera Video Processor (CVP) System-on-Chip (SoC) designed for high-resolution sensor automotive applications. The GW5300 includes GEO’s proprietary 5th-generation eWARP? geometric processor, innovative High Dynamic Range (HDR) Image Signal processor (ISP), and 2D graphics functionality. Designed in a 28nm process to enable small, low power automotive cameras on-the-edge, the GW5300 supports ASIL B and AEC Q100 Grade 2.
The HDR ISP supports up to 8MP30 or 5MP60, and LED Flicker Mitigation (LFM) techniques by pairing with the latest automotive sensors from On Semi, Sony, Omnivision, Samsung, Panasonic, and ST. GW5300’s on-chip combining of up to four exposures drives dynamic range up to 145dB. The 2D Vector Graphics Engine renders high resolution real-time graphics to overlay on the video stream enabling compelling user interfaces.
The GW5300 reduces system component count by requiring no external DDR memory and incorporating dual camera inputs. GW5300 based designs can be rapidly brought to market by leveraging GEO’s SDK and EVK.

GEO SEMI ANNOUNCES HIGH RESOLUTION ADAS AND AUTONOMOUS DRIVING SYSTEMS DESIGN WINS
GEO Semi Announces High Resolution ADAS and Autonomous Driving Systems Design Wins
The GW53x0 Product Provides High Resolution Solutions for Future ADAS and AD Automotive Systems
SAN JOSE, Calif. , July 28, 2020 GEO Semiconductor Inc. (“GEO”), the market leader in camera video processors (CVP) for automotive cameras, today announced new design wins for Autonomous and ADAS system applications using the GW53x0 product and supporting high resolution and HDR processing.
GEO’s application specific camera video processors include both the GW4 and GW5 product lines. These products feature world class high dynamic range image processing, geometric processing, featuring GEO’s eWARP? technology, overlay graphics, and in the case of the GW54x0, a DSP processor for computer vision processing.
Leveraging a versatile design architecture with a small package footprint, low power design, and low cost, without requiring an external DRAM memory, the GW4 and GW5 products stand out as a solution to a number of camera and video applications in the fast developing automotive market.
Today, GEO is engaged with multiple OEMs and industry processor partners for Advanced Driver Assistance (ADAS) and Autonomous Driving (AD) system solutions. For these applications GEO’s GW53x0 product supports high resolution (8 megapixel), high dynamic range automotive image sensors with unique Color Filter Array patterns such as RGGB, RCCB, and RYYCy. The GW53x0 enables customers to customize the image quality to support viewing outputs as well as optimizing the tuning to feed today’s Computer Vision processors for decision making in ADAS or AD applications.
“The GW53x0s high resolution HDR capability, ASIL B support, and the eWARP? processors ability to correct distortion and provide Region of Interest (ROI) selection make it an ideal processor for many ADAS applications,” said John Casey, GEO VP and GM for Automotive. “With design wins at traditional OEM’s, many of the emerging AD system and ride sharing companies, as well as solutions with multiple Autonomous Driving chip suppliers, GEO is well positioned to participate in the next generation ADAS and AD automotive application space.”
The GW53x0 is in Mass Production, supports up to 12 megapixel resolution, full HDR processing, and is capable of processing RGGB, RCCB, and RYYCy color filter sensor designs. The product supports integration into ASIL B systems, and simultaneously outputs a YUV color processed video stream while providing a RAW video stream over CSI-2 MIPI outputs. The GW5300 is available in 7mm x 7mm BGA package with 0.50mm ball pitch and the GW5310 is available in 10mm x 10mm BGA package with 0.65mm ball pitch.
