ADSP-2161:  DSP Microcomputers With ROM

Product Details

The ADSP-216x processors provide the option of custom ROM programming to users of ADSP-2100 Family devices. Pin compatible to the ADSP-2101, -2115, and -2105, the ADSP-216x family can reduce system cost in these designs by eliminating the need for any external memory devices.


  • 25 MIPS, 40 ns Maximum Instruction Rate (5 V)
  • 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
  • Double-Buffered Serial Ports with Companding Hardware, Automatic Data Buffering and Multichannel Operation
  • Three Edge- or Level-Sensitive Interrupts
  • Low Power IDLE Instruction
  • PLCC and MQFP Packages
