GENERAL DESCRIPTION

The ADSP-BF538/ADSP-BF538F processors are members of the Blackfin family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction set architecture.

FEATURES

Up to 500 MHz high performance Blackfin processor

Two 16-bit MACs, two 40-bit ALUs, four 8-bit video ALUs,

40-bit shifter

RISC-like register and instruction model for ease of

programming and compiler friendly support

Advanced debug, trace, and performance monitoring

0.8 V to 1.2 V core VDD with on-chip voltage regulation

3.3 V tolerant I/O with specific 5 V tolerant pins

316-ball Pb-free mini-BGA package
