TheADSP-BF531/ ADSP-BF532 /ADSP-BF533processors are members of the Blackfin®family of products, incorporating the Analog Devices, Inc./Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single instruction, multiple data (SIMD) multimedia capabilities into a single instruction set architecture.The ADSP-BF531 / ADSP-BF532 / ADSP-BF533 processors are completely code and pin-compatible, differing only with respect to their performance and on-chip memory. Specific performance and memory configurations are shown in Table 1.PERIPHERALSParallel peripheral interface PPI, supporting ITU-R 656 video data formats2 dual-channel, full duplex synchronous serial ports, supporting eight stereo I2S channels2 memory-to-memory DMAs8 peripheral DMAsSPI-compatible portThree 32-bit timer/counters with PWM supportReal-time clock and watchdog timer32-bit core timerUp to 16 general-purpose I/O pins (GPIO)UART with support for IrDAEvent handlerDebug/JTAG interfaceOn-chip PLL capable of frequency multiplication
