16-bit, 75 MIPS, 2.75v, 2 Serial Ports, Host Port, 256 KB RAM

The ADSP-2188M is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. 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-pin LQFP package.
