Parameters measured using the following measurement circuits. VSS −2.0 −1.55 −1.2 V Operating current consumption IDD No load − 0.15 0.25 µA Reset input current2 2. The current flowing from the VDD pin into the RESET pin. IRST VRST = VDD − 6 − nA Reset input resistance RRST VRST = −1.35V 15 35 60 k Ω Test input current3 3. IIH, IIL are the input current values with clock stopped when TEST is H, L, respectively. IIH VIH = 0V − 13 µA IIL VIL = −1.55V − 13 µA Motor output current1 IMOT RL = 2kΩ, VSS = −1.55V ± 0.7 −− mA Movement period Normal mode TCY − 2 − sec Test mode tCY − 62.5 − msec Motor pulsewidth TPW − 3.9 − msec Oscillator startup voltage VSTA −1.3 −− V Oscillator startup time4 4. The time interval from when power is applied until the 512Hz output on the TEST pin. TSTA − 2 5 sec Frequency voltage deviation ∆f/f VSS = −1.2 to −2.0V, CTR = 5pF − 0.2 1 ppm/0.1V Frequency deviation5 5. ε’ = [f (1.55V) − f’0] / f’0 where f’0 is the oscillator center frequency under the same measurement conditions. ε’ −8 − 8 ppm Internal capacitance6 6. CG is measured between VDD − XT, and CD is measured between VDD − XTN. Measurement conditions: f = 40kHz, 50mVp-p CG (CG + CD) < 62pF, CG, CD min 5pF − 5 − pF CD − 17 − pF |
