Silan Semiconductors TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE AND DUAL-TONE MELODY DESCRIPTION SC91415 SERIES The SC91415 is a series of tone/pulse switchable dialers that is composed of T/P dialer and T/P dialer with 13 set memories. The SC91415 series provide necessary functions of telephone set for application in any environment, such as Pulse dialing, Tone (DTMF) dialing, Handfree dialing, keying tone and lock functions. The lock function is designed to inhibit toll dialing operation. Beside this, melody generator, ring detector and SDO (Serial Data Output) functions are provided in advance version. Melody generator will output dual-tone music in line hold duration. Ring detector can prevent illegal dialing from pocket dialer. The SDO is designed to drive LCD driver and voice synthesizer. DIP-18 DIP-22 FEATURES *Tone/Pulse switchable *Wide operating voltage from 2.0 V to 5.5 V *Low operating current, 0.15mA (Pulse) and 0.3mA (Tone) typically *Adding resistor on keyboard scan pin that can select many telephone specifications, such as: Pulse rate, M/B ratio, Flash time, lock dialing functions. *Lock function provides conventionality key lock and password lock operations *Ring detector is designed to prevent illegal dialing from pocket dialer *13 set one touch or (3 set one touch and 10 set two touch) repertory memory, each one can hold data up to 16 digits *A 32-digit LNB (last number) redial memory *Handfree function provides on-hook dialing and speakerphone application *Pause and P-T time are fixed to 3.6 seconds *Tone duration and inter-tone pause time are fixed to 98 ms *Using 3.579545 MHz crystal or ceramic resonator *SDO function supports LCD driver and voice synthesizer to indicate dialing numbers. *Line hold function is designed for stopping conversation temporality *Melody generator provides music on hold function *Keytone function provides rapidly keying recognition ORDERING INFORMATION SC91415AP SC91415BP SC91415CK SC91415DK DIP-18 Package DIP-20 Package DIP-22 Package DIP-24 Package HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2001-11-13 1 Silan Semiconductors PIN CONFIGURATIONS SC91415 SERIES COL5 1 2 3 4 5 6 7 8 9 10 SC91415BP 20 HDO 19 PO 18 ROW4 17 ROW3 16 ROW2 15 ROW1 14 HKS 13 VDD 12 DTMF 11 HFO 18 HDO 17 PO 16 ROW4 COL4/KT COL3 COL2 COL1 XIN XOUT XMUTE VSS HFI COL5 COL4/KT COL3 COL2 COL1 XIN XOUT XMUTE VSS 1 2 3 4 5 6 7 8 9 SC91415AP 15 ROW3 14 ROW2 13 ROW1 12 HKS 11 VDD 10 DTMF ROW6 1 COL5 2 COL4/KT 3 COL3 4 SC91415DK COL2 5 COL1 6 XIN 7 XOUT 8 XMUTE 9 VSS 10 HFI 11 DRING 12 24 ROW5/ SDO ROW6 COL5 COL4/KT 1 2 3 4 5 6 7 8 9 SC91415CK 22 23 HDO 22 PO 21 ROW4 20 ROW3 19 18 17 16 15 14 13 ROW2 ROW1 HKS XOUT VDD XMUTE DTMF VSS 10 HFO HFI 11 RMUTE COL1 XIN COL3 COL2 ROW5/ SDO 21 HDO 20 PO 19 ROW4 18 ROW3 17 ROW2 16 ROW1 15 HKS 14 VDD 13 DTMF 12 HFO VERSIONS LIST AND FUNCTION OUTLINE Version SC91415A SC91415B SC91415C SC91415D LNB     KT     HOLD(music)     LOCK           HF SDO(LCD) PDP Note: PDP = Pocket Dialer Prevented HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2001-11-13 2 Silan Semiconductors BLOCK DIAGRAM SC91415 SERIES SDO HFO HDO RMUTE XMUTE COL1 COL2 COL3 COL4 /KT COL5 XIN Oscillator XOUT Keyboard interface Input circuit ROW6 (Row) Timing/Control circuit Pulse generator PO Keyboard interface (column) Memory (Melody) latch & decoder D/A converter DTMF Output circuit Row/Column programming counter ROW1 VDD HFS HKS DRING VDD KEYBOARD ASSIGNMENT COL1 ROW1 ROW2 ROW3 ROW4 ROW5/SDO ROW6 1 4 7 */T M1 M6 COL2 2 5 8 0 M2 M7 COL3 3 6 9 # M3 M8 COL4/KT HD F A RD/P M4 M9 COL5 EM1 EM2 EM3 ST M5 M10 Note: ROW5/SDO: Option by COL5, When ROW5 is selected by R option (COL5), there are 13 sets one touch memory version in SC91415C/D provided.
