Notes: 1. The maximum possible VLCD voltage that can be generated is dependent on voltage, temperature and (display) load.

2. Internal clock

3. When fsclk = 0 there is no interface clock.

4. Power-down mode. During power-down all static currents are switched-off.

5. If external VLCD, the display load current is not transmitted to IDD

6. Tolerance depends on the temperature; (typically zero at Tamb = 27°C), maximum tolerance values are measured at the temper-

ature range limit.

7. For TC0 to TC7

8. Data Byte Writing Mode
