ADSP-2185M:  16-bit, 75 MIPS, 2.5v, 2 serial ports, host port, 80 KB   RAM
     ADSP-2185M是一款单芯片微电脑产品,针对数字信号处理(DSP)以及其他高速数字处理应用进行了优化。ADSP-2185M将ADSP-2100系列的基础架构(三个计算单元、数据地址生成器和一个程序序列器)与两个串行端口、一个16位内部DMA端口、一个字节DMA端口、一个可编程计时器、标志I/O、广泛的中断功能及片内程序和数据存储器完美地结合起来。ADSP-2185M集成80K字节的片内存储器,其配置为16K字(24位)程序RAM和16K字(16位)数据RAM。同时配有省电电路,以满足采用电池供电的便携式设备的低功耗需求。ADSP-2185M采用100引脚LQFP封装。
     The ADSP-2185M is a single-chip microcomputer optimized for digital signal   processing (DSP) and other high speed numeric processing applications.The ADSP-2185M 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, extensive interrupt capabilities, and on-chip program and data   memory.The ADSP-2185M integrates 80K bytes of on-chip memory configured as 16K words   (24-bit) of program RAM, and 16K words (16-bit) of data RAM. Power down   circuitry is also provided to meet the low power needs of battery operated   portable equipment. The ADSP-2185M is available in 100- pin LQFP package.
