16-Bit, 75 MIPS, 2.5V, 2 Serial Ports, Host Port, 40 KB RAM

The 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 archi- tecture (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, exten- sive interrupt capabilities, and on-chip program and data memory. The ADSP-2186M 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 pro- vided 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 manipulationsbit set, bit clear, bit toggle, bit test new ALU constants, new multiplication instruction (?squared), biased rounding, result-free ALU operations, I/O memory trans- fers, 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. The ADSP-2186Ms flexible architecture and comprehensiv instruction set allow the processor to perform multiple opera- tions in parallel. In one processor cycle, the ADSP-2186M can: By Analog Devices, Inc.
