The new Blackfin processors, the BF512, BF514, BF516 and BF518 are all single-core convergent processors that surpass outdated, heterogeneous MCU + DSP approaches in reducing part-count, system cost, board space, and power consumption. Like discrete DSPs, the BF51x processors feature high clock rates and low power dissipation per unit of processing (mW/MMACS), and like discrete MCUs, these convergent processors are compiler-friendly. The ADSP-BF51x series maintains focus on driving system-level reductions in cost, power consumption, complexity, and time-to-market.

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™ 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.

The new Blackfins are ideal for portable, VoIP telephony and industrial instrumentation applications:

The BF512 is the new low-cost entry point in the Blackfin processor family. The device balances performance, peripheral integration, and price, and is well suited for the most cost-sensitive applications including portable test equipment, embedded modems, biometrics, and consumer audio. All members of the BF51x family also include a new 3-phase PWM generation unit for inductive motor control applications and a quadrature interface for rotary encoders.

The BF514, BF516, and BF518 all extend the convergent processor family further into the portable application space with on-chip removable-storage interfaces. All three devices include Secure Digital Input Output (SDIO) for connectivity to standard flash memory and Wi-Fi cards; a power-optimized CE-ATA storage interface for small form-factor handheld and consumer electronics applications; and an embedded multimedia card (eMMC) interface for integrating mass-storage flash memory in a wide range of consumer electronics, wireless, navigation, and industrial applications.
