This version: Feb. 1999

GENERAL DESCRIPTION

The ML9060 consists of a 320-bit shift register, a 320-bit data latch, 160 sets of LCD drivers, and

a common signal generator circuit.

The LCD display data is input serially to the shift register from the DATA IN pin in

synchronization with the CLOCK IN signal, and is stored in the data latch by the LOAD IN

signal.

The LCD display data stored in the data latch is output via the LCD drivers.

A maximum of 160 segments of LCD can be driven in static display mode and a maximum of

320 segments can be driven directly in the 1/2 duty display mode.

It is possible to select the mode of using the internal oscillator circuit or the mode of using an

external clock for the common signal generator circuit. The ML9060 also outputs the sync signal

during the 1/2 duty display mode.

FEATURES

• Logic power supply

: 2.7 to 5.5V

• LCD Driving voltage

: 4.5 to 16V

• Maximum number of segments that can be driven:

Static display mode

: 160 segments

1/2 Duty display mode : 320 segments

• Serial transfer clock

: 1 MHz max.

• The microcontroller interface consists of the three signals DATA IN, CLOCK IN, and LOAD

IN.

• An RC oscillator circuit is built in which can use either an external resistor or the internal

resistor.

• Cascade connection of several ICs is possible.

• Built-in common signal generator circuit.

• Built-in common output mid-level voltage generator circuit.

• Input for turning all segments ON is available (SEG-TEST IN).

• Input for turning all segments OFF is available (BLANK IN).

• Gold bump chip
