AIE Adaptive Image Enhancer Series Real Time Video Processor ICs BU1572GUW, BU1573KV, BU1574KU No.09060EBT02 Description BU1572GUW/BU1573KV/BU1574KU is AIE : Adaptive Image Enhancer (image processing technology by ROHMs 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 2 or the 2-wire serial interface (I C) *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 Supply power Input Control Output Parameter PWM Output Package Interface Interface Interface source voltage 2 1.4-1.6(V Core) Supported up to Max I C BUS 18bit RGB interface Image adjustment DD BU1572GUW VBGA063W050 1.65-3.3(V Io) WVGA+(864480) (At RGB interface) or bus interface PWM output DD 2 1.4-1.6(V Core) Supported up to Max I C BUS 18bit RGB interface Image adjustment DD BU1573KV VQFP64 Io) WVGA+(864480) 2.7-3.6(V (At RGB interface) or bus interface PWM output DD 8bit YUV=4:2:2 parallel 1.4-1.6(V Core) Supported up to Max image adjustment DD 2 BU1574KU I C BUS CCIR601 UQFP64 2.7-3.6(V Io) WVGA+(864480) PWM output DD CCIR656 Absolute maximum ratings (Ta=25) Recommended operating range Parameter Symbol Rating Unit Parameter Symbol Rating Unit Supply power Supply power source VDDIO -0.3+4.2 V VDDIO 1.653.30(Typ:2.85V) *1 V source voltage 1 voltage 1IO Supply power Supply power source VDD -0.3+2.1 V VDD 1.401.60(Typ:1.50V) V source voltage 2 voltage 2CORE VIN -0.3VDDIO+0.3 V Input voltage range VIN-VDDIO 0VDDIO V Input voltage Storage Operating Tstg -40+125 Topr -20+70 *2 temperature range temperature range Power dissipation PD 310 *1 mW *Please supply power source in order of VDDVDDIO. *In the case exceeding 25C, 3.1mW should be reduced at the rating 1C. *1 : BU1573KV and BU1574KU correspond to 2.703.60V(Typ:3.00V) (BU1573KV: 7.5mW / BU1574KU: 7mW should be reduced at the rating.) *2 : BU1573KV and BU1574KU correspond to 40+85 *1: BU1573KV is 750mW, and BU1574KU is 700mW. www.rohm.com 2009.04- Rev.B 1/12 2009 ROHM Co., Ltd.
