ML9472

Semiconductor ML9472 Static,1/2Duty 60 Output LCD Driver FEDL9472-02 Issue Date: Feb. 1, 2008 GENERAL DESCRIPTION The ML9472 is a LCD driver which can directly drive up to 60 segments in the static display mode and up to 120 segments in the 1/2 duty dynamic display mode. FEATURES O perating range Supply voltage : 3.0 to 5.5 V Operating temperature range : 40 to  105C S egment output Static display mode : Up to 60 segments can be displayed. 1/2 duty : Up to 120 segments can be displayed. Simple interface with microcomputer Built-in common signal generator One-to-one correspondence between input data and output data When input data is at “H” level : Display goes on. When input data is at “L” level : Display goes off. Test pin for all-on (SEG_TEST) and all-off (BLANK) Can be cascade-connected Can be synchronized with the external common signal Applicable as an output expander P ackage 80-pin plastic TQFP (TQFP80-P-1212-0.50-K) (Product name: ML9472TB) 1/18 http://www.Datasheet4U.com FEDL9472-02 LAPIS Semiconductor ML9472 BLOCK DIAGRAM SEG1 SEG60 SEG_TEST BLANK 60-Dot Segment Driver 60-Ch Data Selector 60 60 LOAD 60-Bit Latch (A) 60-Bit Latch (B) CLOCK DATA_IN 60 60 60-Stage Shift Register (A) 60-Stage Shift Register (B) DATA_OUT2 DATA_OUT1 D/S EXT/INT 1/4 or 1/8 OSC_OUT VLC1 1/2 VLC2 OSC_OUT OSC_IN OSC Common Driver COM_A COM_B COM_OUT SYNC SYNC Circuit VDD GND 2/18 FEDL9472-02 LAPIS Semiconductor ML9472 PIN CONFIGURATION...
