CF
• 400 kHz
• 4 MHz
LC5824, LC5823, LC5822
Circuit type
Notes
Divider
• The cycle time is 4 times n times the f1
period. (n:1)
• The divider circuit outputs (ø1 through ø15)
are used as the clock time base, the LCD
drive frequency generation clock, and for
S/K port chattering prevention.
Xtal
• 32 kHz
• 55 kHz
Divider
• The cycle time is 4 times the f2 period.
• The divider circuit outputs (ø1 through ø15)
are used as the clock time base, the LCD
drive waveform generation clock, and for
S/K port chattering prevention.
Note that the CFIN and CFOUT pins are
switched over to function as the P1 and P2
pins.
