Product Details

The ADSP-218xN series consists of six single chip microcomputers optimized for digital signal processing applications. All series members are pin-compatible and are differentiated solely by the amount of on-chip SRAM. This feature combined with ADSP-21xx code compatibility provide a great deal of flexibility in the design decision. Specifically, the series members are -

  • ADSP-2184N (4K PM/4K DM) 
  • ADSP-2186N (8K PM/8K DM) 
  • ADSP-2185N (16K PM/16K DM)
  • ADSP-2187N (32K PM/32K DM) 
  • ADSP-2189N (32K PM/48K DM)
  • ADSP-2188N (48K PM/56K DM)

The ADSP-218xN series offers the highest performance (80Mhz/MIPS) and lowest power consumption (0.55mW/MIP @ 1.8V) within the ADSP-218x portfolio. All series members are offered in a 100-lead LQFP and 144-Ball MBGA packages.
