ADSP-2181KSZ-160

Digital Signal Processor Dsp Overview

The ADSP-2181KSZ-160 is a single-chip microcomputer optimized for digital signal processing, fabricated in a high-speed CMOS process. It operates with a 25 ns instruction cycle time at 5.0 Volts, delivering 40 MIPS sustained performance. The device integrates 80K bytes of on-chip RAM, configured as 16K words (24-bit) of program memory and 16K words (16-bit) of data memory. It features three independent computational units: an ALU, a multiplier/accumulator, and a barrel shifter. The processor supports dual operand fetches per cycle via a 3-bus architecture and includes two serial ports, a 16-bit internal DMA port, and a byte DMA port.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KSZ against official Analog Devices documentation to confirm package type and temperature range. Confirm current production status as older SHARC family members may be discontinued. Ensure compatibility with existing development tools such as the EZ-KIT Lite or EZ-ICE emulator interfaces.

Digital Signal Processor Dsp Selection Notes

Select this component when code compatibility with the broader ADSP-2100 family is required alongside extended instruction set features. Consider the 128-lead TQFP/PQFP package constraints for PCB layout. Evaluate the 5.0V I/O voltage levels against system interface requirements. Review the specific memory configuration needs for program versus data storage flexibility.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-2100 family, which utilizes the SHARC architecture. The ADSP-2181 extends the base architecture with additional integration including on-chip memory and serial ports. It maintains code compatibility with earlier ADSP-2100 devices while offering enhanced multifunction instructions and lower power modes.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the ADSP-2100 family include the ADSP-2183, ADSP-2185, and ADSP-2186 series. These variants offer similar architectural foundations but may differ in memory size, clock speed, or peripheral integration. Verify pinout and software compatibility before substitution.
