Low Power Blackfin with Consumer Devices Connectivity

The Blackfin processor family is extended further into the portable market with the availability of an on chip removable storage interface including SDIO, CE-ATA and eMMC. The high performance 16/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem, and the dynamic power management (DPM) functionality allow system designers a flexible platform to address a wide range of connected applications, including PMP and WiFi devices.

IP protection has become a necessary part of today’s embedded computing applications. The ADSP-BF514F provides a security scheme which balances flexibility and upgradeability with performance through the inclusion of a firmware-based solution including OTP (One Time Programmable) memory to enable users to implement private keys for secure access to program code.

The BF514F includes an integrated 4Mb serial Flash (SPI) memory alongside the processor.
