The ADSP-2188M 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-2188M integrates 256K bytes of on-chip memory configured as 48K words (24-bit) of program RAM, and 56K 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-2188M is available in a 100-lead LQFP package and 144 Ball Mini-BGA.

In addition, the ADSP-2188M 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-2188M operates with a 13.3 ns instruction cycle time. Every instruction can execute in a single processor cycle.
