V6123

Digitally Programmable 2,4 and 8 multiplex LCD Driver

Description

Features

ꢀ Very simple 1-bit interface (see Fig.1)

ꢀ V6123 mux mode 2 with 2 rows and 58 columns

ꢀ V6123 mux mode 4 with 4 rows and 56 columns

ꢀ V6123 mux mode 8 with 8 rows and 52 columns

ꢀ Very simple1-bit interface, reduced to its simplest form

ꢀ Frame frequency on chip by internal RC oscillator

ꢀ Voltage bias and mux signal generation on chip

ꢀ 1 display RAM addressable as 8 X 60 bit words

ꢀ Column driver only mode to have 60 column outputs

ꢀ No busy states

ꢀ No external components needed

ꢀ Blank function for LCD blanking

ꢀ Bit mapped

ꢀ Wide VDD voltage supply range, 2 to 6V

ꢀ Wide VLCD voltage supply range, 2 to 8.5V

ꢀ -40°C to +85°C temperature range

The V6123 is low multiplex LCD driver. The 2, 4 and 8

way multiplex is digitally programmable by the command

byte. The display refresh is handled on chip by an internal

RC oscillator via 1 selectable 8 x 60 RAM which holds the

LCD content driven by the driver. LCD pixels (or

segments) are addressed on a one to one basis with the 8

x 60 bit RAM (a set bit corresponds to an activated LCD

pixel).

The V6123 has very low dynamic current consumption,

typically 175 µA at VDD = 5V, VLCD = 7V making it

particularly attractive for portable and battery powered

products. The wide operating range on supply voltages

and temperature offers much application flexibility. The

LCD bias generation and frame frequency are generated

on chip. The clock signal can be used to shift and to latch

the datas into the RAM.

Applications

ꢀ Automotive displays

ꢀ Telephones

ꢀ Pagers

ꢀ Portable, battery operated products

ꢀ Large displays (public information panels etc.)

ꢀ Balances and scales

ꢀ Utility meters
