Analog Devices expands Blackfin processor line

Analog Devices Inc. has added the four-member ADSP-BF54x family to its
16/32-bit Blackfin processor line. The new devices target embedded automotive and industrial applications. The new devices offer increased input/output and memory bandwidth and on-chip memory. They also integrate controller area network (CAN) and media-oriented system transport (MOST) peripherals and include Lockbox Secure Technology designed to protect software code and to provide a platform for digital rights management copy protection.

The ADSP-BF542 is available at 400 MHz, 533 MHz and 600 MHz and ranges from $11.95-$15.65 in 10,000-unit quantities. The ADSP-BF544 ($13.25-$15.35) is available at 400 MHz and 533 MHz, the ADSP-BF548 ($15.95-$17.95) at 533 MHz and 600 MHz, and the ADSP-BF549 ($18.58) at 533 MHz.

John Croteau, general manager of Analog Devices’ Convergent Platforms and Services Group, said the ADSP-BF54x family doubles Blackfin’s internal bus bandwidth of to 532 MB per second, and the new devices include up to 260 Kbytes of on-chip memory. On-chip peripheral options include high-speed USB on-the-go (OTG) with integrated PHY, an ATAPI controller, and a NAND flash controller. Up to 152 general-purpose I/O ports are supported, as is an MXVR (Media Transfer) interface that integrates automotive telematics and infotainment systems with vehicles through a MOST network.

The new processors are supported by ADI CROSSCORE software and hardware development tools that include the VisualDSP++ integrated development and debug environment (IDDE), emulators, and EZ-KIT Lite evaluation hardware.
