Munich Analog Devices, Inc. will come to Electronica, here this week (nov. 13) previewing the newest members of its Blackfin DSP family, targeted at multimedia/networked in-vehicle automotive among other applications.
"Our newest Blackfin family brings developers more of what they need to design performance-hungry and connectivity-ready electronics for a variety of markets, including automotive and industrial," said John Croteau, general manager, Convergent Platforms and Services Group, Analog Devices, Inc. (Norwood, Mass.) According to Croteau, the company's new ADSP BF54x family offers a balance of increased I/O and memory bandwidth, on-chip memory, and integration of system peripherals. Automotive applications include digital radio, audio jukebox, navigation, driver assistance, rear seat audio and video and handsfree phone operation.
The family also embeds ADI's new Lockbox Secure Technology that's been developed to protect developers' software code. This technology allows developers to ensure code and data integrity through authentication, and to safeguard confidentiality by means of encrypting any or all of the system. Not only does this provide a means for developers to protect the intellectual property of their own products, but it also offers a platform for the digital rights management (DRM) content protection that is required for devices such as media players. In addition, the programmable aspect of the Lockbox software-based system gives system designers the opportunity to choose any encryption algorithm they prefer.
The new Blackfin DSPs are likely to go head-to-head against the popular C55x and C64x DSPs from Texas Instruments, the IMX processors from Freescale Smiconductor, and the rapidly emerging ARM9 and ARM11 microcontrollers from a growig list of ARM licensees, among other processors and vendors.
Operating at speeds up to 600MHz, the new ADSP BF542/BF544/BF548/BF549 DSPs double the internal bus bandwidth of Blackfin to 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. Additionally, the high-performance processing is complemented by a rich set of integrated peripherals that reduces system cost and development risk by minimizing the need for external components, according to Croteau.
While the Blackfin core hasn't changed from the earlier devices, ADI has added features to make it easier to move data on and off the chip inorder to improve bandwidth. There are different tiers of on-chip memory. The BF548/549 are at the high end with 260 KBytes of RAM; the BF544 is at the mid-range with 196 KBytes of RAM; the BF542 is aimed at less memory intensive applications with 132 KBytes of RAM. Also on-chip is up to 128 KBytes of level 2 unified instruction/data SRAM.
The BF548/549 and BF542 embed the high Speed USB on-the-go (OTG) with integrated PHY. The ATAPI controller, LCD interface and NAND flash controller are just a few of the peripheral options on the ADSP-BF54x family, not to mention the availability of up to 152 general-purpose I/O ports. Furthermore, these new Blackfin processors offer a Multimedia Device Interface (MDI) that easily integrates automotive telematics and infotainment systems with vehicles. There are CAN interfaces for automotive applications. The ADI CROSSCOR software and hardware development tools that support other Blackfin Processors support the ADSP-BF54x family. These tools include the VisualDSP++ integrated development and debug environment (IDDE), emulators, and EZ-KIT Lite evaluation hardware.

The Blackfin BF54x family is also aimed at a wide variety of industrial application, including those where field upgradeability is critical. The signal processing performance and rich peripheral set on the Blackfin BF54x family allows the ability to access a hard drive, power a display, and run machine vision or imaging. All of this can be upgraded through the USB peripheral in the field, removing the need to connect back to a central servicing unit. Potential applications include industrial control and factory automation, security and access control systems as well as avionics communications, wireless telecommunications, radios and related equipment.
The BF54x units are packaged in 400-ball, 17mm x 17mm MBGAs with 0.8 mm pitch. All of the new devices operate in the -40 C to +85 C temperate range. The BF542 runs at 0 C to +70 C ambient at 600 MHz.
Available today, the ADSP-BF542 is available at 400MHz, 533MHz and 600 MHz. They are priced at $11.95, $13.50 and $15.65 respectively. The ADSP-BF544 is available at 400 MHz and 533MHz and ranges from $13.25-$15.35. The ADSP-BF548 is available at 533 MHz and 600 MHz and ranges from $15.95-$17.95. The ADSP-BF549 is available only for automotive applications at 533 MHz and priced at $18.58. All prices are based on 10,000-unit quantities. Samples will be available in the first quarter of 2007. Preproduction is targeted at the second quarter with full production scheduled for the third quarter of next year.
