zr36430/zr36431 product brief t el 408.919.4 1 1 1 fax 408.919.4122 www.zoran.com 09/02-ld overview zorans COACH 5 is the fifth camera on a chip (COACH) digital camera processor. COACH 5 is firmware compatible with previous COACH processors, thus instantly providing a mature camera devel- opment platform. COACH 5 is offered in two versions: COACH 5e (zr36430), supporting up to 2.3 megapixel sensors, and COACH 5p, (zr36431) supporting up to 4 megapixel sensors. for the cam- era developer, both versions have identical features and interface sets. the two versions provide cost effectiveness across the entry level and mid-range digital camera market segments. the COACH 5 includes all required hardware and firmware to sup- port: two- and three-field interlaced sensors, progressive sensors, cmos sensors, view-lcd display, tv output, flash memory of all types, usb, rs232, and stereo/speech audio recording/playback. the COACH 5 digital camera processor offers value and perform- ance due to its flexible and programmable architecture that supports a wide range of camera designs. COACH 5 eliminates the need for an external microcontroller. internal a/d converters and additional general-purpose io pins were added. user interface software can be implemented within the COACH 5. rom/nor-type devices are no longer needed and the COACH 5 program can be stored on the same resident nand-type flash memory used for image storage. three-field ccd support, lens shading compensation (patent pending) and a smooth digital zoom allow significant cost savings for sensor and optics. COACH 5 emphasizes image quality with true 10-bit enhanced sen- sor processing. the COACH 5 comes with a complete development package that includes a "manufacture-ready" cammini reference design, a com- prehensive set of software development tools, and whql approved pc drivers. zoran corporation 3112 scott boulevard santa clara, ca 95054-3317 zr36430/zr36431-pb-3.0 ? user i/f buttons user i/f leds image sensor (ccd or cmos) flash bulb circuit rs-232c usb conn.
