S6A0071

32COM/60SEG DRIVER & C O N T R O L L E R F O R D O T MATRIX LCD S6A0071 INTRODUCTION The S6A0071 is a dot matrix LCD controller & driver LSI which is fabricated by low power CMOS technology. It can display 1 line × 24 characters or 2 line × 24 characters with 5 × 7 dots format. FUNCTION Character type dot matrix single chip LCD controller & driver Internal driver: 32 common and 60 segment signal output Easy interface with 4-bit or 8-bit MPU Display character pattern: 5 × 7 dots format (240 kinds) The Special character pattern is programmable by character generator RAM directly. A customer character pattern is programmable by mask option. Various instruction functions Built-in automatic power on reset Driving method is B-type (frame inversion) FEATURES Internal Memory Character Generator ROM (CGROM): 8,400 bits (240 characters × 5 × 7 dots) Character Generator RAM (CGRAM): 64 × 8 bits (8 characters × 5 × 8 dots) Display Data RAM (DDRAM): 80 × 8 bits ( 80 characters max.) Low Power Operation Power supply voltage range (VDD): 2.4 to 5.5V LCD drive voltage range (VDD - V5): 3.0 to 12.0V Voltage doubler generates about double from signals power supply On chip generation of LCD supply voltage from voltage doubler (external supply also possible) Programmable duty cycle 1/16 duty: 1 line × 5 × 7 dots + cursor × 24 characters 1/32 duty: 2 lines × 5 × 7 dots + cursor × 24 characters Internal oscillator with an external resistor 118 TCP or bare chi...
