| General description |
The V6123 is a 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 8x60 RAM which holds the LCD con tent driven by the driver. LCD pixels (or segments) are ad dressed on a one to one basis with the 8x60 bit RAM (a set bit corresponds to an activated LCD pixel).
The V6123 has a very low dynamic current consumption, 175mA (typ) 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 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 data into the RAM.
