AN494 - An HC11-Controlled Multiband RDS Radio

General Description

of the application, and the listed software, corresponds to the E32 ROMed version (ZC403311).

Later sections list the port allocation and functional differences which apply to the PH8 ROMed versions (ZC428200 and ZC428202).

Key Features

  • of the microcontroller (MCU) of a synthesized multiband radio which includes RDS (radio data system) decoding (FM, band II). It uses an MC68HC(7)11 MCU whose program can be on-chip or contained in an external EPROM (erasable programmable read-only memory). ROM versions are available. Both LCD (liquid crystal display) and VFD (vacuum fluorescent display) 16-character dot matrix display modules can be used to display RDS and tuning information. Traffic messages, initiated by the reception of EON (.
