• Manufacturer Part Number: S1D1
• Description: LCD Controller-driver With Built-in Character ROM
• Manufacturer: Epson Electronics America, Inc.

Relationship between display data RAM and addresses (if initial display line is 08):
Display Timing Generator Circuit
This section explains how the display timing generator circuit
operates.
Signal generation to line counter and display data latch
circuit
The line address counter, RAM, and latch circuit of the S1D15206
series operate synchronous to the display clock (the oscillator circuit
outp).mm The LCD drive signal is sent to LCD panel driver output
pin SEGn.

The timing of LCD panel driver outputs is independent of the timing
of RAM data input from microprocessor.
LCD AC Signal (FR)
The LCD AC signal, FR, is generated from the display clock. The
FR controller generates dual-frame AC driver waveforms for LCD
panel driver circuit.
