Blackfin is a registered trademark of Analog Devices, and ADSP-BF534/ADSP-BF536/ADSP-BF537 are the model numbers of Blackfin embedded processors. This document introduces the features and characteristics of ADSP-BF534/ADSP-BF536/ADSP-BF537, including 600 MHz high-performance processor, two 16-bit MAC, two 40-bit ALU, four 8-bit video ALU, 40-bit shifter, RISC-like register and instruction model, advanced debug, trace, and performance monitoring, 0.8 V to 1.2 V core voltage, 2.5 V and 3.3 V compatible I/O, 182-ball and 208-ball MBGA packages.
The handbook describes the ADSP-BF534, ADSP-BF536 and ADSP-BF537 Blackfin embedded processors, members of the Blackfin family that combine dual‑MAC DSP engines with a RISC‑like core. It outlines the high‑performance features such as up to 600 MHz operation, on‑chip voltage regulation, and a rich set of peripherals including Ethernet, CAN, SPI, UART, and multiple timers.
The document also details the memory hierarchy (up to 132 KB on‑chip memory, L1 instruction and data SRAM/cache, scratchpad SRAM), external memory interfaces (SDRAM, asynchronous memories), event handling, interrupt architecture, and power‑management capabilities. Technical tables, block diagrams, and pin‑out information support developers in designing and debugging systems based on these processors.

Only the ADSP‑BF536 and ADSP‑BF537 have an IEEE 802.3‑compliant 10/100 Ethernet MAC.
The processors provide 48 general‑purpose I/Os, of which 8 have high‑current drivers.
The on‑chip voltage regulator can supply core voltages from 0.8 V to 1.2 V.
