ADSP-2184BSTZ-160

Digital Signal Processor Dsp Overview

The ADSP-2184BSTZ-160 is a fixed-point digital signal processor from the ADSP-2100 family, fabricated in a high-speed CMOS process. It features a 25 ns instruction cycle time, delivering 40 MIPS sustained performance with single-cycle execution for all instructions. The device integrates 20K bytes of on-chip memory, configured as 4K words (24-bit) of program RAM and 4K words (16-bit) of data RAM. Key architectural components include three independent computational units (ALU, MAC, shifter), two data address generators, and a powerful program sequencer supporting zero-overhead looping.

Digital Signal Processor Dsp Feature Summary

• 3-Bus Architecture enabling dual operand fetches and parallel computation in every instruction cycle.
• Integrated 20K Bytes On-Chip Memory: 4K x 24-bit Program RAM and 4K x 16-bit Data RAM.
• Dual Serial Ports (SPORTs) with hardware companding, automatic data buffering, and UART emulation capabilities.
• Flexible System Interface supporting Host Mode (16-bit IDMA) and Full Memory Mode (Byte DMA to 4MB space).
• Low Power Operation including Power-Down mode with 200-cycle recovery, Idle mode, and Slow Idle mode.

Digital Signal Processor Dsp Applications

• High-performance fixed-point digital signal processing applications requiring code compatibility with the ADSP-2100 family.
• Battery-operated portable equipment utilizing low power dissipation and power-down modes.
• Systems requiring glueless interface design for off-chip RAM and I/O peripherals.
• Audio processing and serial communications using SPORTs with A-law/m-law companding.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix BSTZ against the manufacturer's official documentation to confirm package type, temperature range, and lead-free status. Ensure the target system supports the required 100-lead LQFP footprint. Confirm that the development environment includes compatible tools such as the ADSP-2100 Family Development Software or EZ-KIT Lite for debugging and compilation.

Digital Signal Processor Dsp Selection Notes

Select this component when a single-chip solution with integrated memory and extensive I/O is required for fixed-point DSP tasks. The ADSP-2184 is suitable for applications needing dual serial ports and flexible memory mapping via Host or Full Memory modes. Consider the 40 MIPS performance and 25 ns cycle time for real-time processing requirements. Ensure the application can utilize the ICE-Port interface for in-system debugging if necessary.

Digital Signal Processor Dsp Part Context

The ADSP-2184 belongs to the ADSP-2100 family of microcomputers, which are optimized for digital signal processing. This family shares a common base architecture, ensuring code compatibility across members. The ADSP-2184 specifically enhances the base architecture with integrated on-chip memory, dual serial ports, and DMA controllers, distinguishing it from earlier models like the ADSP-2181 which may have different memory configurations or peripheral sets.

Digital Signal Processor Dsp Replacement Considerations

For direct replacements within the same family, consider the ADSP-2181, ADSP-2185, ADSP-2186, or ADSP-2187. Verify pin compatibility and memory size differences. The ADSP-218x series generally maintains architectural compatibility, but specific feature sets like on-chip memory capacity and peripheral availability vary between models. Consult the ADSP-2100 family datasheets for detailed comparison matrices.
