NEC => Renesas Technology 

MOS INTEGRATED CIRCUIT

µPD16430A

1/2, 1/3, 1/4 DUTY LCD CONTROLLER/DRIVER

The µPD16430A is an LCD controller/driver that enables the display of LCDs of 1/2 duty, 1/3 duty and 1/4 duty

cycle.

The LCD controller contained in the µPD16430A employs serial data transfer and uses an automatic increment

function for data addresses which eliminates the need to set addresses newly each time.

The LCD driver uses a medium voltage output (14 V max.), which enables higher contrast and a wider viewing angle

even with a 1/3 or 1/4 duty cycle.

By using an on-chip drive bias circuit, it is possible to eliminate the need for external resistors.

FEATURES

• LCD direct drive (medium voltage output: 14 V MAX.)

• Choice of 3 duty cycles

1/2 duty, 1/3 duty, 1/4 duty

• Display dot number:

1/3 duty: 160

1/4 duty: 240

• 2 types of drive bias

1/2 bias, 1/3 bias

• Choice of 4 types of frame frequency

• Multi-chip configuration possible

• Control through 8-bit serial interface

• On-chip power-on reset circuit

• Low-power dissipation CMOS

• 3.5 to 6.0 V logic supply voltage
