1 / 6 page NIPPON PRECISION CIRCUITS INC. NIPPON PRECISION CIRCUITS-1 OVERVIEW CF5732 Series Analog clock CMOS IC The CF5732 series are analog clock driver ICs using 32kHz reference frequency of crystal oscillator. Some versions in accordance with the combinations of each motor drive and alarm output characteristics can provide a wide range of applications for various clock specifica- tions. The CF5732 series incorporates 4 types of pace adjust- ment capacitors, which enables to adjust the pace with bonding options. FEATURES - Built-in oscillator circuits(32.678 kHz) On-chip feed back resistors (Rf, Rd) Crystal oscillator capacitors (CD, CG) Additional 4 capacitors for pace adjustment. - Debounce circuit (AI terminal) - Single 1.5 V supply - Available as a die SERIES LINEUP CF5732EA CF5732FA CF5732GA CF5732HA CF5732JA CF5732KA Built-in XT terminal CG(pF) 11.5 11.5 10 11.5 11.5 11.5 Capacitor XT terminal CD(pF) 29 29 25 29 29 29 C1(pF) 6 6 3666 C2(pF) 7 7 4777 C4(pF) 8 8 5888 C4(pF) 9 9 6999 Motor Active Level - H L H H H Output Hand Drive Cycle(sec) 0.125 1 1111 Pulse Width(msec) DUTY50% 31.25 31.25 15.6 23.4375 46.875 Alarm Active Level L L LLLL Input Test Function Yes(1/2VDD) Yes(1/2VDD) Yes(1/2VDD) Yes(1/2VDD) Yes(1/2VDD) Yes(1/2VDD) Alarm Terminal AO AO AO AO AO AO AO AO AO AO AO AO Output Active Level H L(*1) H L(*2) H L(*1) H L(*2) H L(*2) H L(*2) Fundmental Frequency(Hz) 2048 2048 2048 2048 2048 2048 2048 2048 2048 2048 2048 2048 Modulation Frequency(Hz) 8 +1 8 +1 8 +1 8 +1 8 +1 8 +1 16 +116+18+18+18+18+1 IOH MIN(mA) −1.0 −1.0 −1.0 −1.0 −1.0 −1.0 IOL MIN(mA) 1.0 1.0 1.0 1.0 1.0 1.0 (*1) AO is the reverse phase of AO, when output is active. (the same phase, when output is inactive) (*2) AO is complete reverse phase of AO. (even output is inactive.) |
