ADSP-2191M:  16-bit Fixed-Point DSP, 160 MIPS, 160K bytes RAM

Product Details


The ADSP-2191 is a 160 MIPS 16-bit fixed point DSP that is software compatible with DSPs in the ADSP-218x family, noted for its easy-to-use algebraic assembly syntax. Although the architectures are compatible, the ADSP-2191 architecture incorporates a number of enhancements that enables significant performance increases and improved C-compiler efficiency over its predecessor. The ADSP-2191 is available in a 144-lead LQFP and 144-ball mini-BGA package and is pin compatible with the low cost ADSP-2196 with 16K words RAM and 16 words ROM and the ADSP-2195 with 32K words RAM and 16K words ROM. Pin to pin-compatibility allows programmers a simple migration path to smaller memory models to reduce system cost without hardware redesign.

Development Tools

The ADSP-2191 is supported by a complete set of software and hardware development tools including VisualDSP++™, evaluation boards,and JTAG emulators.

The VisualDSP++ integrated development and debug environment (IDDE) features an efficient C/C++ compiler, statistical profiling, and the new VisualDSP® Kernel (VDK) - all designed to make software development faster.

ADI makes it easier to evaluate the ADSP-2191 for a specific application with the ADSP-2191 EZ-KIT Lite™ evaluation system. The EZ-KIT Lite includes an ADSP-2191 DSP evaluation board and evaluation suite with VisualDSP++.

FEATURES and BENEFITS

  • 160 MIPS 16-bit fixed-point DSP
  • 160K bytes of on-chip RAM, configured as 32K words 24-bit RAM and 32K words 16-bit RAM
  • 16-bit parallel port interface supports SRAM, FLASH, or EPROM memory devices
  • Host port with DMA capability for glueless interface to 8- or 16-bit host processors
  • Three multichannel serial ports support A-law or µ-law companding, and T1/E1/H100 telecommunications standards
  • UART Port; Two SPI-compatible ports with slave select hardware
  • User selectable low-power operating modes
  • 10x10mm BGA / 144 Lead LQFP Packages; -40ºC to +85ºC ambient temperature range
