Analog Devices Blackfin Block Diagram 1

The Blackfin Processor core combines a 32-bit RISC-like instruction set with 16-bit dual MACs (multiply/accumulate units) and targets convergent applications, those with a mix of signal processing (audio, video), and traditional control and data processing.

The Blackfin processor family includes devices that target applications in the consumer, automotive, industrial, instrumentation, and communications markets. To address these markets, the Blackfin processor family offers scalable performance from the 200 MHz ADSP-BF535 to the dual core 600 MHz ADSP-BF561 to the ADSP-BF52x with advanced peripherals to the low power ADSP-BF51x family with real-time Ethernet capabilities and the ADSP-BF50x with 4 MB onboard executable flash memory and a 12-bit dual SAR ADC (analog-to-digital converter).

Packaging options include miniBGA and a sparse PBGA.

The Blackfin ADSP-BF54x family features increased I/O and memory bandwidth, on-chip memory, and integration of high bandwidth multimedia peripherals such as USB, ATAPI, SD, NAND, and up to 24-bit LCD display drive capability. The Blackfin ADSP-BF54x family supports CAN and MOST system peripherals to target industrial and multimedia/networked in-vehicle automotive applications. It also embeds Lockbox secure technology to protect customers' intellectual property. Operating at speeds up to 600MHz, the ADSP-BF54x family features an internal bus bandwidth of 532-Mbytes per second to meet the demands of system peripheral integration. This internal bandwidth is matched by up to 260-kbytes of on-chip memory. Up to 152 general-purpose I/O ports are supported. These Blackfin processors offer a MXVR (Media Transfer) interface that integrates automotive telematics and infotainment systems with vehicles through a MOST network.

The ADSP-BF536 and ADSP-BF537 processors integrate IEEE-compliant 802.3 10/100 Ethernet MAC, and feature an enhanced DMA system for high network-bandwidth capability and also embeds a CAN module which is capable of up to 1-Mbps data rates. The ADSP-BF537 features up to 64-kbytes of embedded memory, enabling higher throughput needs for embedded-system applications, such as video security/surveillance and industrial-environment-based distributed-control and factory-automation applications. The ADSP-BF536 targets low-cost connected devices, such as remote monitoring devices, VoIP (Voice over Internet Protocol), and biometrics applications.

The ADSP-BF534 processors' system peripherals include an integrated CAN 2.0B controller; a two-wire interface controller; UART and SPI ports; external DMA request lines; 32-bit timers (some with PWM capability); a real-time clock; a watchdog timer; and a parallel peripheral interface. The ADSP-BF534 integrates a fully compliant CAN 2.0B module capable of data rates of up to 1 Mbps. The CAN module supports up to 32 mailboxes with individual acceptance masks and data filtering.

The ADSP-BF531 and ADSP-BF532 provide a low cost, power-efficient processor targeting convergent signal processing applications. With power consumption as low as 0.23 mW/MHz and performance of 400 MHz, applications can now add greater signal processing performance without sacrificing battery life.

The ADSP-BF533 provides a high performance, power-efficient processor targeting convergent signal processing applications. With performance up to 600 MHz (1200 MMACS), applications can now add greater signal processing performance without significantly increasing their system cost. The high performance 16-/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem and the dynamic power management (DPM) functionality allow system designers to address consumer, communications, automotive, and industrial/instrumentation applications.
