Product Summary

The ADSP-2191MBSTZ-140 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-2191MBSTZ-140 integrates 64K words of on-chip memory configured as 32K words (24-bit) of program RAM, and 32K words (16-bit) of data RAM. Power-down circuitry is also provided to reduce power consumption. The ADSP-2191MBSTZ-140 is available in 144-lead LQFP and 144-ball mini-BGA packages. Fabricated in a high-speed, low-power, CMOS process, the ADSP-2191MBSTZ-140 operates with a 6.25 ns instruction cycle time (160 MIPS). All instructions, except single-word instructions, execute in one processor.
