Preliminary
TONE/PULSE DIALER WITH
REDIAL FUNCTION
CMOS IC
DESCRIPTION
The UTC U9131X series are monolithic ICs that offer the dialing
signals in either pulse or tone mode. The UTC U9131X series
feature a redial memory.
FEATURES
* Uses 4×4 keyboard
* Pulse-to-tone (P→T) keypad for long distance call operation
* Easy operation with redial, flash, pause, and P→T keypads
* 32 digits for redial memory
* Flash, Pause, P→T (pulse-to-tone) can be stored as a digit in
memory
* Switchable dialing mode：DTMF/Pulse
* Switchable beak/make ratio
* Minimum tone output duration: 100mS
* Minimum intertone pause: 100mS
* On-chip power-on reset
* Uses 3.579545MHz crystal or ceramic resonator

Notes:1. Crystal parameters suggested for proper operation are Rs<100Ω, Lm=96mH, Cm=0.02pF, Cn=5pF,
CI=18pF, FOSC=3.579545MHz ± 0.02%.
2. Crystal oscillator accuracy directly affects these times.
