ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are highly integrated system-on-a-chip solutions for the next generation of digital communication and consumer multimedia applications. By combining industry-standard interfaces with a high performance signal processing core, users can develop cost-effective solutions quickly without the need for costly external components. The system peripherals include a UART port, an SPI port, two serial ports (SPORTs), four general-purpose timers (three with PWM capability), a real-time clock, a watchdog timer, and a parallel peripheral interface.
