MOS INTEGRATED CIRCUIT
μ
PD16431A
The
μ
PD16431A is an LCD controller/driver that enables display of segment type LCDs of 1/2, 1/3, or 1/4 duty
cycle. This controller/driver has 56 segment output lines of which eight can also be used as LED output lines.
Because the LCD driver contained in the
μ
PD16431A has separate logic and power supply, up to 6.5 V of LCD
drive voltage can be set. In addition, key source output lines for key scanning and key input data lines are
also provided, so that the
μ
PD16431A is ideal for applications in the front panel of an automobile stereo system.
FEATURES
Various display modes
1/2 duty: 112 segment outputs or 96 segment outputs + 8 LED outputs
1/3 duty: 168 segment outputs or 144 segment outputs + 8 LED outputs
1/4 duty: 224 segment outputs or 192 segment outputs + 8 LED outputs
Key scan circuit (key source outputs are shared with LCD driver outputs)
Independent LCD driver power supply V
LCD
(can be set to V
DD
to 6.5 V)
Serial data input/output (SCK, STB, DATA)
On-chip oscillator incorporated
Power-ON reset circuit
