RDS PIRA32 Manuals

Pira.cz PIRA32 Microcontroller FM Broadcast Radio Data System Encoder MCU with single communication port DESCRIPTION The PIRA32 Microcontroller forms a fully digital Radio Data System encoder that has been developed especially for FM broadcasting. It implements physical and data-link layers and supports extended set of RDS services. All functions are controlled by the RS-232 interface. The device supports optional I2C slave peripherals such as EEPROM memory, RTC, LCD display or digital potentiometer. FEATURES  Single supply  Typical operating current: 9 mA @ 5 V  Minimum external parts  I2C bus for external peripherals like EEPROM, real time clock, LCD or digital potentiometer  External TA and Program switch  Two indication LED outputs  Both stereo and mono operation possible  Built-in digital 19 kHz pilot tone PLL with software phase shift adjustment  Parallel 8-bit D/A converter, 361 kHz sampling rate (over-sampled)  Broadcast quality output signal  Only simple output filter required  RDS/RBDS signal: conforms to CENELEC EN50067 / EN 62106  Continuous RDS transmission during all operations  Firmware update capability  Communication bus: RS-232, bidirectional  Baud rate: 1200 to 19200 Bd  Packages available: 28-Pin PDIP 28-Pin SOIC TYPICAL APPLICATIONS  FM broadcast RDS encoders with single communication port  RDS testing, research and development Important Note: This datasheet is not intended to be a complete PIRA32 system designer’s reference source.
