Notes

1. LCD outputs are open-circuit; inputs at VDD or VSS; V0 =VDD; bus inactive; internal or external clock with duty cycle

50% (IDD1 only).

2. LCD outputs are open-circuit; LCD supply voltage generator is on; load current at VLCD =20 µA.

3. Resets all logic when VDD <VPOR.

4. When the voltages are above or below the supply voltages VDD or VSS, an input current may flow; this current must

not exceed

±0.5 mA.

5. Tested on sample basis.

6. Resistance of output terminals (R1 to R32 and C1 to C60) with load current = 150

µA; VOP =VDD − VLCD =9V;

outputs measured one at a time; (external VLCD).

7. LCD outputs open-circuit; external VLCD.

8. Maximum value occurs at 85

°C.

15 DC CHARACTERISTICS (PCF2116K)

VDD = 2.5 to 6 V; VSS =0V; VLCD =VDD − 3.5 to VDD − 9 V; Tamb = −40 °C to +85 °C; unless otherwise speciﬁed.

Note

1. R0 has a temperature coefficient of resistance of +0.6%/K.
