DescriptionThe ADSP-2186M is a single-chip microcomputer optimized for digital signal processing (DSP) and other high-speed numeric processing applications.
The ADSP-2186M 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 integrates 40K bytes of on-chip memory configured as 8K words (24-bit) of program RAM, and 8K 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-2186M is available in a 100-lead LQFP package and 144 Ball Mini-BGA.
In addition, the ADSP-2186M supports new instructions, which include bit manipulations-bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (* squared), biased rounding, result-free ALU operations, I/O memory transfers, and global interrupt masking, for increased flexibility.
Fabricated in a high-speed, low-power, CMOS process, the ADSP-2186M operates with a 13.3 ns instruction cycle time. Every instruction can execute in a single processor cycle.
