产品详情
The ADSP-2185 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.
The ADSP-2185 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-2185 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-2185 is available in 100-pin LQFP package.
In addition, the ADSP-2185 supports new instructions, which include bit manipulations- bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking, for increased flexibility.
