Analog Devices is targeting low-power,
high-performance applications with the
BF51x low-end additions to the Blackfin family.
Targeted at signal-processing chores for
multimedia products, the 400-MHz BF51x
devices have a standby power requirement
under 1 mW and use 1.8-V I/O. They can
deliver 8.5 MMACs/mW. Two SPI, two
UARTs, two audio serial ports, and an
Ethernet MAC with IEEE-1588 time synchronization
support provide connectivity. The
Ethernet MAC is particularly handy for networked
control applications. The BF51x family
also offers a 16-bit SDRAM interface, 8
kbytes of OTP Lockbox memory, 512 kbytes
of flash, and 4 kbytes of RAM plus 48 kbytes
of instruction and 64 kbytes of data cache/
memory (see the figure). A 4-Mbit SPI boot
flash device can be integrated with the chip.
The chips can handle SDIO, CE-ATA, and
eMMC storage interfaces. Pricing starts at
$4.95. A uClinux Voice over Internet Protocol
(IP) reference platform is also available.
