Six-Bit ASCll Data input pins (active high).
Chip Select from µP address decoder, etc.
WRite pulse input pin (active low). For an active high write pulse, CS can be used, and WR
can be used as CS.
Selects data entry MODE. High selects Sequential Access (SA) mode where first entry is
displayed in “leftmost” character and subsequent entries appear to the “right”. Low selects
the Random Access (RA) mode where data is displayed on the character addressed via
A0 - A2 Address pins.
In RA mode it is the LSB of the character Address. In SA mode it is used for cascading
devices for displays of more than 8 characters (active high enables device controller).
In RA mode this is the second bit of the address. In SA mode, a low input will CLeaR the
Serial Address Counter, the Data Memory and the display.
In RA mode this is the MSB of the Address. In SA mode, the output goes high after eight
entries, indicating DISPlay FULL.
OSCillator input pin. Adding capacitance to V
An external oscillator can be applied to this pin. A low at this input sets the device into a
(shutdown) mode, shutting OFF the display and oscillator but retaining data stored in
memory.
SEGment driver outputs.
CHARacter driver outputs.
No Connect
