ST7528
Bare Dice Consumption Current : During Display, with the Internal Power Supply, Current consumed by total ICs when an
external power supply(VDD,VDD2) is used .
Notes to the DC characteristics
1. The maximum possible V
2. Internal clock
3. Power-down mode. During power down all static currents are switched off.
4. If external V
5. V
