ML9480
Static, 1/2 Duty, 1/3 Duty, 1/4 Duty 40 Outputs LCD Driver
FEDL9480-01
Issue Date: Oct. 1, 2012
GENERAL DESCRIPTION
The ML9480 is an LCD driver LSI, consists of a 40-bit shift register, a 160-bit data latch, 40 sets of LCD drivers,
and a common signal generation circuit.
It can directly drive an LCD up to 40 segments for static display, 80 segments for 1/2-duty display, 120
segments for 1/3-duty display, and 160 segments for 1/4-duty display.
The three-wire serial interface and I²C interface are selectable.
