INTRODUCTION

The S6B0724 is a single chip driver & controller LSI for graphic dot-matrix liquid crystal display systems. This chip can beconnected directly to a microprocessor, accepts serial or 8-bit parallel display data from the microprocessor, stores the display data in an on-chip display data RAM of 65x 132bitsand generates a liquid crystal display drive signal independent of the microprocessor.

FEATURES

Display Driver Output Circuits

- 65 common outputs / 132segment outputs

On-chip Display Data RAM

- Capacity: 65x 132= 8,580 bits

- RAM bit data “1”: a dot of display is illuminated.

- RAM bit data “0”: a dot of display is not illuminated.

Microprocessor Interface

- High-speed 8-bit parallel bi-directional interface with 6800-series or 8080-series

- Serial interface (only write operation) available

Various Function Set

- Display ON / OFF, set initial display line, set page address, set column address, read status, write / read display data, select segment driver output, reverse display ON / OFF, entire display ON / OFF, select LCD bias, set/reset modify-read, select common driver output, control display power circuit, select internal regulator resistor ratio for V0 voltage regulation, electronic volume, set static indicator state.

- H/W and S/W reset available

- Static drive circuit equipped internally for indicators with 4 flashing modes

Built-in Analog Circuit

- On-chip oscillator circuitfor 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/°Cor 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): 2.4to 3.6V

- LCD driving voltage (VLCD= V0 - VSS): 4.5to 15.0 V

Low Power Consumption

- Operating power: 40mA typical. (condition: VDD= 3V, x 4 boosting (VCI is VDD), V0 = 11V, internal power supply ON, display OFFand normal mode is selected)

- Standby power: 10mAmaximum. (during power save[standby] mode)

Operating Temperatures

- Wide range of operating temperatures : -40 to 85°C

CMOS Process

Package Type

- Gold bumped chip
