Notes

1. As the programming range for the internally generated VLCD allows values above the maximum allowed VLCD, the

user has to ensure, while setting the VOP register and selecting the temperature compensation, that the VLCD limit of

maximum 9 V will never be exceeded under all conditions and including all tolerances.

2. LCD outputs are open circuit, inputs at VDD or VSS; bus inactive.

3. VDD1 to VDD3 = 2.85 V; VLCD = 7.0 V; voltage multiplier = 3 × VDD; fOSC = 34 kHz.

4. VDD1 to VDD3 = 2.75 V; VLCD = 9.0 V; fOSC = 34 kHz.

5. VDD1 to VDD3 = 2.75 V; VLCD = 3.5 V; fOSC = 34 kHz.

6. Resets all logic when VDD1 <VPOR.

ILOAD≤ 50 µA; outputs tested one at a time.

8. VLCD ≤ 7.7 V.
