ASX340/MT9V139 Data Sheet
For the latest data sheet, refer to Aptina’s Web site: www.aptina.com
Features
• Low-power image sensor with integrated image flow processor (IFP) and video encoder
• 1/4-inch optical format, VGA resolution (640H x 480V )
• 2x upscaling zoom and pan control • ±40 additional columns and ±36 additional rows to
compensate for lens alignment tolerances • Option to use single 2.8V 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 • Auto black level calibration • 10-bit, on-chip analog-to-digital converter (ADC) • Internal master clock generated by on-chip phaselocked 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
• Analog surveillance CCTV • Surveillance network IP camera
