Analog Devices Blackfin BF51x Convergent Processors

Analog Devices, Inc. (NYSE: ADI) recently introduced the Blackfin BF51x series convergent-processor family. The new Blackfin processors are the BF512, BF514, BF516 and BF518. All are single-core convergent processors that surpass outdated, heterogenous MCU+DSP approaches in reducing part-count, system cost, board space, and power consumption. Like traditional DSPs, the BF51x processors feature high clock rates and low power dissipation per unit of processing (MMACs/mW), and like traditional MCUs, these convergent processors are OS and compiler-friendly. The BF51x family includes the BF512 at $4.95, the BF514 at $7.75, the BF516 at $8.75 and the BF518 at $11.85. Processors are sampling immediately. All prices are based on 25,000-unit quantities.

All four of the new 16-/32-bit BF51x processors are available at clock speeds up to 400 MHz (800 MMACS) and include 116 kBytes of RAM plus an optional 4 Mbits of serial (SPI) flash memory. Each also integrates Lockbox[tm] security for code and content protection. Owing to the needs of low power, rich media applications where Blackfin processors are best suited, on-chip integration assures easy connection to a variety of audio, video, imaging and communications peripherals and memory types. Integrated features include support for sixteen stereo I2S digital-audio channels, twelve peripheral DMA channels, and an advanced memory controller for glueless connection to multiple banks of external SDRAM, SRAM, Flash, or ROM. Each processor includes two dual-channel synchronous serial communication ports (SPORTs), a high-speed parallel peripheral interface (PPI), an I2C compatible two-wire interface (TWI), dual PC-compatible UARTs, and 2 SPI-compatible serial peripheral interface ports.

All of the new Blackfin processors, delivering 8.5 MMACs/mW (100 MHz), include dynamic power management (DPM) functionality that lets developers match the processor’s power consumption to processing requirements during program execution. ADI pioneered the application of DPM more than seven years ago with the release of the first Blackfin processors – devices that have consistently maximized power efficiency since debuting in October 2001.
