Overview

  • 25 ns instruction cycle time (40 MIPS)
  • 4K words of on-chip program RAM
  • 4K words of on-chip data memory RAM
  • 16-bit internal DMA port for high speed access to on-chip memory
  • 8-bit DMA port to byte memory for transparent program and data memory transfers
  • 1.4 mA/MIPS
  • Byte memory interface for storage of data tables and program overlays
  • Programmable memory strobe and separate I/O memory space permits "glueless" system
  • ADSP-2100 Family code and function compatible 100-lead LQFP

The ADSP-2184L is a member of the ADSP-218x family. The ADSP-2184L is one of the lowest cost pin compatible devices in the ADSP-218x family. It can be designed into systems the same way as all other ADSP-2100 devices.

The ADSP-2184L combines the ADSP-2100 family base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, and extensive interrupt capabilities.

Benefits

  • Algebraic assembly language supports C language-style constructs for easy programming
  • 100-lead LQFP package provides for space and power savings (16mm x 16mm)
  • On-chip RAM and 4 DMA ports make reprogramming easy
  • 16-bit DMA port makes bus interfacing easier
  • 5 sleep and powerdown modes maximize battery life.
