SC91312A

Silan Semiconductors TONE / PULSE DIALER WITH REDIAL FUNCTION DESCRIPTION SC91310 Series The SC91310 series are monolithic ICs that provide the necessary signals for either pulse or tone dialing. The SC91310 series feature a redial memory. FEATURES *DTMF / Pulse switchable dialer *32 digits for redial memory *pulse-to-tone (P→T) keypad for long distance call operation *Break / Make ratio is selectable by pin option *Uses 4x4 keyboard *Easy operation with redial, flash, pause, and P→T keypads *Flash, pause, P→T (pulse-to tone) can be stored as a digit in memory *Minimum tone output duration:100ms *minimum intertone pause: 100ms *On-chip power-on reset *Uses 3.579545 MHz crystal or ceramic resonator *Packaged in 18-pin plastic DIP DIP-18 ORDERING INFORMATION (The different dialers in the SC91310 series are shown in the following table) Type No. SC91312/A SC91314/A SC91316 Pulse(pps) 10/20 10/20 10/20 Flash(ms) 600/300 73/100 600 Flash pause(ms) 600/300 140/100 600 Pause(s) 2.0 3.6 3.6 PIN CONFIGURATIONS C1 C2 C3 C4 B/M VSS XT XT T/P MUTE 1 2 3 4 5 6 7 8 9 SC91310 18 R4 17 R3 16 R2 15 R1 14 VDD 13 MODE 12 DTMF 11 DP 10 HKS HANGZHOU SILAN MICROELECTRONICS CO.,LTD.
