ADSP-2115:  DSP Microcomputer

Product Details

The ADSP-2100 Family processors are single-chip microcomputers optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-21xx processors are all built upon a common core. Each processor combines the core DSP architecture-computation units, data address generators, and program sequencer-with differentiating features such as on-chip program and data memory RAM, a programmable timer, one or two serial ports, and, on the ADSP-2111, a host interface port.


  • 25 MIPS, 40 ns Maximum Instruction Rate
  • Separate On-Chip Buses for Program and Data Memory
  • Program Memory Stores Both Instructions and Data (Three-Bus Performance)
  • Dual Data Address Generators with Modulo and Bit-Reverse Addressing
  • Efficient Program Sequencing with Zero-Overhead Looping: Single-Cycle Loop Setup
  • Three Edge- or Level-Sensitive Interrupts
  • Automatic Booting of On-Chip Program Memory from Byte-Wide External Memory (e.g., EPROM )
  • Double-Buffered Serial Ports with Companding Hardware, Automatic Data Buffering, and Multichannel Operation
  • ADSP-2111 Host Interface Port Provides Easy Interface to 68000, 80C51, ADSP-21xx, etc.
  • Automatic Booting of ADSP-2111 Program Memory Through Host Interface Port
