ADSP-2189MBSTZ-266

Digital Signal Processor Dsp Overview

The ADSP-2189MBSTZ-266 is a fixed-point digital signal processor from the ADSP-21xx family, fabricated in a high-speed CMOS process. It operates with a 13.3 ns instruction cycle time at 2.5 Volts, delivering 75 MIPS sustained performance. The device integrates 192K bytes of on-chip RAM, configured as 32K words (24-bit) of program memory and 48K words (16-bit) of data memory. It features three independent computational units: an ALU, a multiplier/accumulator (MAC), and a barrel shifter. The processor supports flexible I/O structures for 2.5 V or 3.3 V operation and includes two serial ports, a byte DMA port, and a 16-bit internal DMA port.

• Battery-operated portable equipment requiring low power

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BSTZ-266' against the manufacturer's official documentation to confirm package type, temperature range, and speed grade. The provided datasheet confirms the base ADSP-2189M architecture but does not explicitly detail the 'BSTZ-266' variant specifications. Ensure compatibility with development tools such as the EZ-KIT Lite or EZ-ICE emulator for system integration.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring code compatibility with the ADSP-2100 family and efficient loop execution via zero-overhead looping. Consider the 100-lead LQFP package constraints and the need for external memory interfaces if the 192K on-chip RAM is insufficient. Evaluate power-down modes for battery-powered designs.
