Notes:
1. Worst case values occur at an IC junction temperature of 150°C.
2. For designers who do not need to read from the display, the Read line can be tied to V_DD and the Write and Chip Enable lines can be tied to-
gether.
3. Changing the logic levels of the Address lines when CE = “0” may cause erroneous data to be entered into the Character RAM, regardless of
the logic levels of the WR and RD lines.
4. The display must not be accessed until after 3 clock pulses (110 μs min. using the internal refresh clock) after the rising edge of the reset line.
