LCD CONTROLLER/DRIVER
The
μ
PD75308B has an on-chip display controller which generates segment signals and common signals in
accordance with data in display data memory as well as a segment driver and common driver capable of
directly driving the LCD panel.
The configuration of the LCD controller/driver is shown in Fig. 5-7
The functions of the on-chip LCD controller/driver of the
μ
PD75308B are as follows.
Display data memory are read automatically through DMA operations and segment signals and common
signals are generated.
5 different display modes can be selected.
Static
1/2 duty (1/2 bias)
1/3 duty (1/2 bias)
1/3 duty (1/3 bias)
1/4 duty (1/3 bias)
In each of the display modes, 4 types of frame frequency can be selected.
The segment signal output is a maximum of 32 segments (S0 to S31) and 4 common outputs (COM0 to
COM3).
Segment signal outputs (S24 to S27, S28 to S31) are in 4-segment units and they can be switched for use
as output ports (BP0 to BP3, BP4 to BP7).
Split resistors can be built-in for the LCD driver power supply (mask option).
Conformity to various bias methods and LCD driver voltages is possible.
When the display is OFF, the current flowing to the split resistors is cut.
Display data memory not used for the display can be used as ordinary data memory.
Operation by the subsystem clock is also possible.
