ADSP-2184N: 16位、80 MIPS、1.8v，2个串行端口，主机端口，40KB RAM
ADSP-218xN系列包括6款单芯片微电脑，针对数据信号处理应用而优化。系列全部成员均具有引脚兼容特性，差别仅体现在片内SRAM容量上。这种特性再加上ADSP-21xx出色的代码兼容性，可为设计提供极大的灵活性。具体地，该系列的成员有：
- 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)
在ADSP-218x系列产品组合中，ADSP-218xN系列具有最高的性能(80Mhz/MIPS)和最低的功耗(0.55mW/MIP @ 1.8V)。该系列的全部成员均采用100引脚LQFP和144引脚MBGA两种封装。
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.
