ADSP-BF531 Series

Analog Devices initial product family, the ADSP-BF531,ADSP-BF532, andADSP-BF533, offer all the ease of use and architectural attributes of the Blackfin processor. These three processors are all completely pin compatible - differing solely with respect to their performance and on-chip memory - thus reducing risk and offering the ability to scale up or down depending upon the end application needs. All three processors offer low power consumption with scalable performance from low-cost to very high performance.The ADSP-BF531 is the low cost entry point into the Blackfin Processor family. It offers an optimal balance between performance, peripheral integration, and price and is well suited for the most cost-sensitive applications including portable test equipment, embedded modems, biometrics, and consumer audio.HIGH LEVEL OF INTEGRATION52Kbytes of on-chip L1 memory configured as:32Kbytes of L1 instruction memory SRAM/Cache16Kbytes of L1 data memory SRAM/Cache4 Kbytes of L1 scratchpad SRAMParallel Peripheral Interface supporting ITU-R 656 video data formatsTwo dual-channel, full-duplex synchronous serial ports supporting eight stereo I2S channels12 DMA channels supporting one and two-dimensional data transfersMemory controller providing glueless connection to multiple banks of external SDRAM, SRAM, Flash, or ROM.Three timer/counters supporting PWM, pulsewidth, and event count modesUART with support for IrDA®SPI-compatible portEvent handlerReal-time clockWatchdog timerPLL capable of 1× to 63× frequency multiplication160-ball (12mm × 12mm) Mini-BGA, 176-Lead (24mm × 24mm) LQFP, and 169-ball (19mm × 19mm) Pb-Free Sparse PBGA packagesIndustrial temperature range
