AIE Adaptive Image Enhancer Series Real Time Video Processor ICs BU1572GUW, BU1573KV, BU1574KU ●Description BU1572GUW/BU1573KV/BU1574KU is AIE : Adaptive Image Enhancer (image processing technology by ROHM’s hardware). Camera video images are optimized for maximum visibility. ●Features 1) Compatible with image data from QCIF size (176 144) up to WVGA+ size (864 480) 2) Compatible with 80-system CPU bus interface and RGB interface.(BU1572GUW/BU1573KV) 3) Compatible with Input/Output data formats with RGB 5:6:5 and 6:6:6.(BU1572GUW/BU1573KV) 4) Multiple operation modes: Image Enhance, Analysis, Through and Sleep. *1 5) Two selectable register settings: indirect addressing through the 80-system CPU bus interface or the 2-wire serial interface (I 2C) *2 6) PWM output for image adjustment LCD backlight control. 7) Built-in edge-enhancement and gamma filters. *1: BU1574KU is an analysis mode setting interdiction. *2: BU1574KU becomes only the register set by the two-wire system serial interface. * Extra document is prepared separately about each register setup. Please refer to the Development Scheme on page 10. ●Application Portable media player, Mobile phone, car display, Car navigation system, and portable DVD etc. ●Lineup Parameter Supply power source voltage Input Interface Control Interface Output Interface PWM Output Package BU1572GUW 1.4-1.6(VDDCore) 1.65-3.3(VDDIo) Supported up to Max WVGA+(864×480) I 2C BUS (At RGB interface) 18bit RGB interface or bus interface Image adjustment PWM output VBGA063W050 BU1573KV 1.4-1.6(VDDCore) 2.7-3.6(VDDIo) Supported up to Max WVGA+(864×480) I 2C BUS (At RGB interface) 18bit RGB interface or bus interface Image adjustment PWM output VQFP64 BU1574KU 1.4-1.6(VDDCore) 2.7-3.6(VDDIo) Supported up to Max WVGA+(864×480) I 2C BUS 8bit YUV=4:2:2 parallel ・ CCIR601 ・ CCIR656 image adjustment PWM output UQFP64 ●Absolute maximum ratings (Ta=25℃) ●Recommended operating range *In the case exceeding 25ºC, 3.1mW should be reduced at the rating 1ºC. (BU1573KV: 7.5mW / BU1574KU: 7mW should be reduced at the rating.) *1: BU1573KV is 750mW, and BU1574KU is 700mW.
