KS0724
Built-in Analog Circuit
On-chip oscillator circuit for display clock (external clock can also be used)
High performance voltage converter (with booster ratios of x2, x3, x4 and x5, where the step-up reference
voltage can be used externally)
High accuracy voltage regulator (temperature coefficient: -0.05%/°C or external input)
Electronic contrast control function (64 steps)
Vref = 2.1V ± 3% (V0 voltage adjustment voltage)
High performance voltage follower (V1 to V4 voltage divider resistors and OP-Amp for increasing drive
capacity)
Operating Voltage Range
Supply voltage (VDD): 2.4 to 3.6 V
LCD driving voltage (VLCD = V0 - VSS): 4.5 to 15.0 V
Low Power Consumption
Operating power: 40µΑ typical. (condition: VDD = 3V, x 4 boosting (VCI is VDD), V0 = 11V, internal power
supply ON, display OFF and normal mode is selected)
Standby power: 10µΑ maximum. (during power save[standby] mode)
Operating Temperatures
Wide range of operating temperatures : -40 to 85°C
