10. Page address
The display RAM is composed of four pages. When accessing the display data RAM from MPU, the page of the
display data RAM is set a command.
11. CR oscillation circuit
The S-4520BA is built-in a CR oscillation circuit. Oscillation frequency is approximately 18 kHz at Rf 1M
12. LCD drive circuit
The S-4520BA has a 16 common and a 61 segment driver output. An LCD drive waveform which is a two-
frame AC drive method (B) type is generated. Refer to Figure 7, LCD drive waveform.
13. Display timing circuit
The display timing is generated by the clock using a CR oscillation circuit or an external clock, and a frame
signal FR.
When configuring an LCD panel with more than two S-4520BA, the S-4520BA on the slave side syncronizes to
the falling of FR signal. So, on the slave side of the S-4520, the LCD drive waveform is synchronized only by
input of the FR signal on the master side. As shown in Figure 8, the display drive output on the slave side, after
the common output COM15 on master side, is executed in COM16 through COM31. The FR signals are that of
the duty 50 % of synchronized to the COM output timing.
14. Line address
This is the address for reading the LCD RAM data to the LCD data latch. The line address is incremented
synchronizing with the common output. The display start line is set with a command.
15. Display data latch
The display data latch is the circuit for latching one line’s display data from the display RAM. The display data is
output from this latch to the LCD drive circuit. Since the display ON/OFF and the display all-lit ON/OFF control
the display data latch, it has no effect on the display RAM data.
16. Master/Slave selection
Master and slave selection is executed through the master/slave terminal logic. The Master IC and the Slave IC
have different terminal functions.
Note 1
CR oscillation circuit: In slave operation, OSC
1
is at high impedance. OSC
2
is connected to OSC
2
on the
master side as a display clock input terminal.
Common output: Master operation is output counterclockwise from terminal No.96 to No.11.
Slave operation is output clockwise from terminal No.11 to No.96.
