LC75874E, 75874W
1/4-Duty General-Purpose LCD Display Driver
Overview
The LC75874E and LC75874W are 1/4-duty general-
purpose microprocessor-controlled LCD driver that can be
used in applications such as frequency display in products
with electronic tuning. In addition to being able to drive
up to 264 segments directly, the LC75874E and
LC75874W can also control up to 8 general-purpose
output ports.
Since the LC75874E and LC75874W use separate power
supply systems for the LCD drive block and the logic
block, the LCD driver block power-supply voltage can be
set to any voltage in the range 2.7 to 6.0 V, regardless of
the logic block power-supply voltage.
Features
• Support for 1/4-duty 1/2-bias or 1/4-duty 1/3-bias drive
techniques under serial data control (up to
264 segments)
• Serial data input supports CCB format communication
with the system controller.
• Serial data control of the power-saving mode based
backup function and the all segments forced off
function.
• Serial data control of switching between the segment
output port and general-purpose output port functions.
• High generality, since display data is displayed directly
without the intervention of a decoder circuit.
• Independent VLCD for the LCD driver block (VLCD can
be set to any voltage in the range 2.7 to 6.0 V,
regardless of the logic block power-supply voltage.)
• The INH pin allows the display to be forced to the off
state.
• RC oscillator circuit
