Item
LCD driving voltage (VLCD)
The increment and decrement
of the address counter in writing/
reading the data to/from the
CGRAM/DDRAM.
1/4 bias
1/5 bias
3.0 to 11.0 (V)
4.6 to 11.0 (V)
3.0 to 8.0 (V)
Bus interface speed with CPU
1 MHz (1000 ns)
1.5 MHz (667 ns)
Since signal rise/fall time is quite fast,
the electromagnetic induction between
lines of the PCB and the cable
assignment should be noted.
The address counter is incremented
or decremented 6
msec
(when OSC = 250 KHz) after the
busy condition is released.
(Period of busy condition is 40
ms)
So, the data cannot be written into/
read out from the RAM for 6
msec
after the busy condition was over.
The address counter is incremented
or decremented during the busy
condition.
So, data can be written into/read out
from the RAM immediately after the
busy condition was over.
The repeated input frequency
(oscillation frequency=250kHz)
of display clear instruction
610 Hz or less (1.64 ms or more)
78 Hz or less in 5
7 dots (12.8 ms or
more), 56Hz or less in 5
10 dots (17.9
ms or more)
