V6118

2, 4 and 8 Mutiplex LCD Driver

Description

Features

The V6118 is a universal low multiplex LCD driver. The

version V6118 drives two ways multiplex (two

□ V6118 2 is 2 way multiplex with 2 rows and 38 columns

□ V6118 4 is 4 way multiplex with 4 rows and 36 columns

□ V6118 8 is 8 way multiplex with 8 rows and 32 columns

□ Low dynamic current, 150 µA max.

blackplanes) LCD, the version V6118 4, four way

multiplex LCD , and the V6118 8, eight way multiplex

LCD. The display refresh is handled on chip via a 40 x 8

bit RAM which holds the LCD content driven by the driver.

LCD pixels (or segments) are addressed on a one to one

basis with the 40 x 8 bit RAM (a set bit corresponds to an

activated LCD pixel). The V6118 has very low dynamic

current consumption , 150 µA max., making it particularly

attractive for portable and battery powered applications.

The wide operating range on both the logic (V_DD) and the

LCD (V_LCD) supply voltages offers much application

flexibility. The LCD bias generation is internal. The voltage

bias levels can also be provided externally for applications

having large pixels sizes. The V6118 can be used as a

column only driver for cascading in large display

applications. In the column only mode, 40 column outputs

are available to address the display. A BLANK function is

provided to blank the LCD, useful at power up to hold the

display blank until the microprocessor has updated the

display RAM.

□ Low standby current, 1 µA max. at +25°C

□ Voltage bias and mux signal generation on chip

□ Display refresh on chip, 40 x 8 RAM for display storage

□ Display RAM addressable as 8, 40 bits words

□ Column driver only mode to have 40 column outputs

□ Crossfree cascadable for large LCD applications

□ Separate logic and LCD supply voltage pins

□ Wide power supply range: V_DD: 2 to 6V, V_LCD: 2 to 8V

□ BLANK function for LCD blanking on power up etc.

□ Voltage bias inputs for applications with large pixel

sizes

□ Bit mapped

□ Serial input / output

□ Very low external component count

□ -40 to + 85 °C temperature range

□ No busy states

□ LCD updating synchronized to the LCD refresh signal

□ QFP52 and TAB packages
