DESCRIPTION
The M491B is a monolithic N-MOS LSI circuit including a Floating-gate Non- Volatile Memory for storage of up to 16 stations. Tuning of the station is performed with a 8192 step D/A converter, using the principle of voltage synthesis. It is designed for 7-segment LED displays. Direct memory selection is possible only from remote control while Up/Down memory scanning is possible on the set and also from remote control. An option input for 8 or 16 stations is available. The circuit also includes a PCM remote control receiver operating in conjunction with the transmitter M708.
