Notes
1. VDD2 and VDD3 are always equal.
2. The maximum possible VLCD voltage that may be generated depends on voltage, temperature and load (display).
3. Valid for the temperature, VPR and TC values used at calibration.
4. Normal mode and internal clock.
5. Conditions: VDD1 = 1.8 V; VDD2 = 2.70 V; VLCD = 7.6 V; voltage multiplier = 4 × VDD2; bias system 1/9; inputs at VDD1
or VSS; VLCD generation = internal; VLCD output loaded by 10 µA; Tamb = 25 °C.
6. fINTCLK = 0 (no data bus clock).
7. Power-down mode; during Power-down all static currents are switched off.
