1 / 39 page  Silan Semiconductors SC9302 Series HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2001-11-01 1 1-MEMORY/2-MEMORY TONE/PULSE DIALER DESCRIPTION The SC9302 series tone/pulse dialers are CMOS LSIs for the telecommunication system. They are designed to meet various dialing specifications through resistor options matrix. The SC9302 series tone/pulse dialers are offered in four different versions. They are SC9302X normal version, SC9302/F/G/H simple version, SC9302XT key-tone version and SC9302XLT key-tone/lock functions version. The SC9302X normal version provides the pin- selected lock function; the SC9302XT version provides the key-tone function; the SC9302XLT version provides both the key-tone function and key board-operated IDD lock function. All of the above three versions also supply the following functions: Hold-line, Hand-free and LCD dialing number display interface, all of which are suitable for feature phone applications. However, the SC9302F/G/H version is simpler than the other three versions. It provides only a redialing memory for a simple low-cost system application.
