CF5732 Series
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 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
