FUNCTION
6-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.
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 thru 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 8 entries,
indicating DISPlay FULL.
OSCillator input pin. Adding capacitance to V DD will lower the internal oscillator frequency. 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.
