Blackfin Embedded Processor ADSP-BF531/ADSP-BF532/ADSP-BF533 Rev. H is a high performance embedded processor from Analog Devices, Inc. It has two 16-bit MACs, two 40-bit ALUs, four 8-bit video ALUs, and a 40-bit shifter. It is based on the RISC instruction set, making it easy to program and supports a variety of compilers. It also has a wide range of operating voltages and a programmable voltage regulator. It supports a variety of packaging options and has a rich memory and external storage interface.
The ADSP-BF531, ADSP-BF532 and ADSP-BF533 are Blackfin family processors that combine a high‑performance DSP core with a RISC‑like microcontroller. They offer up to 600 MHz operation, dual 16‑bit MAC units, 40‑bit ALUs, video ALUs and a flexible instruction set for signal‑processing applications.
The devices integrate extensive on‑chip memory (up to 148 KB), a memory management unit, external memory controllers, and a rich set of peripherals including UART, SPI, dual SPORTs, parallel peripheral interface, timers with PWM, real‑time clock, watchdog, and programmable voltage regulator. Various package options (CSP‑BGA, PBGA, LQFP) and automotive‑qualified versions are also described.
