CF5732GA

CF5732 Series NIPPON PRECISION CIRCUITS INC. Analog clock CMOS IC OVERVIEW 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 specifications. The CF5732 series incorporates 4 types of pace adjustment 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 Built-in Capacitor XT terminal CG(pF) XT terminal CD(pF) C1(pF) C2(pF) C4(pF) C4(pF) Motor Output Alarm Input Alarm Output Active Level Hand Drive Cycle(sec) Pulse Width(msec) Active Level Test Function Terminal Active Level Fundmental Frequency(Hz) Modulation Frequency(Hz) CF5732FA 11.5 29 6 7 8 9 H 1 31.25 L Yes(1/2VDD) AO H 2048 8+1 1.0 AO L(*2) 2048 8+1 −1.0 CF5732GA 10 25 3 4 5 6 L 1 31.25 L Yes(1/2VDD) AO H 2048 8+1 1.0 AO L(*1) 2048 8+1 −1.0 CF5732HA 11.5 29 6 7 8 9 H 1 15.6 L Yes(1/2VDD) AO H 2048 16+1 AO L(*2) 2048 16+1 CF5732JA 11.5 29 6 7 8 9 H 1 23.4375 L Yes(1/2VDD) AO H 2048 8+1 1.0 AO L(*2) 2048 8+1 CF5732KA 11.5 29 6 7 8 9 H 1 46.875 L Yes(1/2VDD) AO H 2048 8+1 1.0 AO L(*2) 2048 8+1 11.5 29 6 7 8 9 0.125 DUTY50% L...
