V6123

www.DataSheet4U.com R EM MICROELECTRONIC - MARIN SA V6123 Digitally Programmable 2,4 and 8 multiplex LCD Driver Description 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.
