Analog Devices ADSP-BF531/ADSP-BF532/ADSP-BF533 Embedded Processor Handbook
This handbook introduces the ADSP-BF531, ADSP-BF532 and ADSP-BF533 Blackfin processors, members of the Blackfin family that combine a dual‑MAC signal‑processing engine with a RISC‑like core and SIMD multimedia capabilities. It describes the portable low‑power architecture, dynamic power management, and the system‑on‑chip integration that make these devices suitable for digital communication and consumer multimedia applications.
The document also covers the rich set of on‑chip peripherals—including UART, SPI, two SPORT ports, timers with PWM, a real‑time clock, watchdog timer and parallel peripheral interface—along with memory organization, boot modes, event handling, and the core and system interrupt controllers. Detailed memory maps, timing specifications and pin descriptions are provided for hardware designers.
