ASX340AT 1/4‐inch Color CMOS NTSC/PAL Digital Image SOC with Overlay Processor General Description The ON Semiconductor ASX340AT is a VGA-format, single-chip CMOS active-pixel digital image sensor for automotive applications. It captures high-quality color images at VGA resolution and outputs NTSC or PAL interlaced composite video. The VGA CMOS image sensor features ON Semiconductor’s breakthrough low-noise imaging technology that achieves superior image quality (based on signal-to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost, low power, and integration advantages of ON Semiconductor’s advanced active pixel CMOS process technology. The ASX340AT is a complete camera-on-a-chip. It incorporates sophisticated camera functions on-chip and is programmable through a simple two-wire serial interface or by an attached SPI EEPROM or Flash memory that contains setup information that may be loaded automatically at startup. The ASX340AT performs sophisticated processing functions including color recovery, color correction, sharpening, programmable gamma correction, auto black reference clamping, auto exposure, 50Hz/60Hz flicker detection and avoidance, lens shading correction, auto white balance (AWB), and on-the-fly defect identification and correction. The ASX340AT outputs interlaced-scan images at 60 or 50 fields per second, supporting both NTSC and PAL video formats. The image data can be output on one or two output ports: • Composite analog video (single-ended and differential output support) • Parallel 8-, 10-bit digital Features • Low-Power CMOS Image Sensor with Integrated Image Flow • • • • • • • • Processor (IFP) and Video Encoder 1/4-inch Optical Format, VGA Resolution (640 H x 480 V) 2x Upscaling Zoom and Pan Control ±40 Additional Columns and ±36 Additional Rows to Compensate for Lens Alignment Tolerances Option to Use Single 2.8 V Power Supply with Off-Chip Bypass Transistor Overlay Generator for Dynamic Bitmap Overlay Integrated Video Encoder for NTSC/PAL with Overlay Capability and 10-bit I-DAC Integrated Microcontroller for Flexibility On-Chip Image Flow Processor Performs Sophisticated Processing, Such as Color Recovery and Correction, Sharpening, Gamma, Lens Shading Correction, On-the-Fly Defect Correction, Auto White Balancing, and Auto Exposure © Semiconductor Components Industries, LLC, 2014 November, 2018 − Rev. 11 1 www.onsemi.com IBGA63 7.5 y 7.5 CASE 503AE ORDERING INFORMATION See detailed ordering and shipping information on page 3 of this data sheet. • Auto Black-Level Calibration • 10-Bit, On-Chip Analog-to-Digital Converter (ADC) • Internal Master Clock Generated by • • • • • • On-Chip Phase-Locked Loop (PLL) Two-Wire Serial Programming Interface Interface to Low-Cost EEPROM and Flash through SPI Bus High-Level Host Command Interface Stand-Alone Operation Support Comprehensive Tool Support for Overlay Generation and Lens Correction Setup Development System with DevWare Applications • Automotive Rear View Camera and Side Mirror • Blind Spot and Surround View Publication Order Number: ASX340AT/D ASX340AT Table 1.
