LCD Drive Waveform 4 2003-02-06 JT6P24-AS 3. Display Modes and Display Sequences Counter display mode 4. Input Setting S1, S2: Normally, pulled down to the VSS1 level by external resistance. S1 and S2 perform their specified functions when connected to the VDD by an external switch. 5. Input Functions Counter display S1: +1/S1 S2: Count reset Pressing S1 or S2 outputs an operating confirmation sound from BUZZ. (around 30~60 ms) The drive frequency is 4 kHz. 6. All Clear Function When power is applied or when the supply of power is interrupted (e.g. if the battery is changed), the internal state of the IC may become unstable, even though it appears to be operating normally. For this reason it is vital to verify that the crystal oscillation circuit is oscillating normally ant stably (at 32 kHz) and then to use the system reset pin to initialize the IC (i.e. clear it) before use. Note that a clear operation using the built-in power-on clear circuit should not be used in this case. 5 2003-02-06 JT6P24-AS Maximum Ratings (if no temperature stipulations, Ta = 25C) Characteristics Power supply voltage (1) Power supply voltage (2) Input voltage (1) Input voltage (2) Output voltage (1) Output voltage (2) Operating temperature Storage temperature Symbol VSS1-VDD VSS2-VDD VIN1 VIN2 VOUT1 VOUT2 Topr Tstg Rating -3.0~0.2 -4.5~0.2 VSS1 - 0.2~VDD + 0.2 VSS2 - 0.2~VDD + 0.2 VSS1 - 0.2~VDD + 0.2 VSS2 - 0.2~VDD + 0.2 -10~60 -40~125 Unit V V V V V V C C Electrical Characteristics (unless otherwise stated, VDD = 0.00 V, VSS1 = -1.55 V, VSS2 = -3.00 V, CG = 20 pF, W CD = built-in (10 pF), CIMAX = 21 kW, Fo = 32768 Hz) Characteristics Operating voltage Operating current consumption Oscillation start voltage Output current (1) Segment Output current (2) Common Output current (3) Buzzer Input current (2) T1, T3, T4 Input current (3) T2 Input current (4) S1, S2 Voltage doubler output Symbol iVSS1-VDDi iIsupi iVSTAi IOH1 IOL1 IOH2 IOL2 IOH3 IOL3 IIH2 IIL2 IIH3 IIL3 IIH4 IIL4 iVucoi Test Circuit 3 2 3 4 4 4 4 4 4 4 4 4 4 4 4 2 No LCD load tSTA 10 s VOH1 = -0.2 V VOL1 = -2.8 V VOH2 = -0.2 V VOL2 = -2.8 V VSS1 = -1.25 V VOH3 = -0.5 V Test Condition 3/4 Min 1.25 3/4 3/4 3/4 0.5 3/4 4.0 3/4 100 3/4 3/4 3/4 -15.5 3/4 -0.1 3.0 Typ. 1.55 3/4 3/4 3/4 3/4 3/4 3/4 3/4 3/4 3/4 -50 3/4 3/4 3/4 3/4 3/4 Max 1.80 3.0 1.40 -0.5 3/4 -4.0 3/4 -100 mA 3/4 0.1 3/4 0.1 3/4 0.1 3/4 3/4 mA Unit V mA V mA mA VSS2 = -2.8 V VOL3 = -0.75 V VIH2 = 0 V VIL2 = -1.55 V VIH3 = 0 V VIL3 = -1.55 V VIH4 = 0 V VIL4 = -1.55 V C1 = C2 = 0.1 mF, RL = 3 MW mA mA V 6 2003-02-06 JT6P24-AS Test Circuit 1.
