Analog Devices ADSP-BF522/ADSP-BF523/ADSP-BF524/ADSP-BF525/ADSP-BF526/ADSP-BF527 Product Handbook Rev C
This handbook describes the Blackfin ADSP‑BF52x family, highlighting features such as up to 600 MHz core speed, dual 16‑bit MACs, dual 40‑bit ALUs, video ALUs and a 40‑bit shifter. It covers the portable low‑power architecture, on‑chip voltage regulation (for BF523/525/527), and the processor’s RISC‑like instruction set.
The document details memory organization (132 KB on‑chip memory, L1 instruction and data SRAM, scratchpad), extensive peripheral set (USB 2.0 OTG, 10/100 Ethernet MAC, SPI, UART, TWI, NAND flash controller, DMA engines, timers, GPIOs) and system integration aspects such as boot modes, event handling, and automotive qualification.
