ADSP-BF514:  Low Power Blackfin with Consumer Devices Connectivity

Product Description

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-BF514 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.

Features

  • Blackfin processor core with up to 400 MHz (800 MMACS) performance
  • 2 dual-channel, full-duplex synchronous serial ports supporting 8 stereo I2S channels
  • 12 peripheral DMA channels supporting one- and two-dimensional data transfers
  • Connectivity: SDIO, CE-ATA, eMMC, UART’s, SPORT’s, SPI and TWI
  • Lockbox™ Secure Technology: Hardware-enabled security for code and content protection
  • Memory controller providing glue-less connection to multiple banks of external SDRAM, SRAM, Flash, or ROM
  • 176-p, 0.5 mm pitch, 24 X 24 LQFP (Industrial temperature range -40°C to +85°C)
  • 168-ball, 0.8 mm pitch, 12x12 mm CSP-BGA (Commercial temperature range
    0°C to +70°C)
