32COM/60SEG DRIVER &CONTROLLER FOR DOTMATRIX 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 chip available
