DSP56321VL200R2

Digital Signal Processor Dsp Overview

The DSP56321 is a 24-bit digital signal processor from the DSP56300 family, designed for high-performance applications such as networking and security encryption. It features a single-clock-cycle-per-instruction engine compatible with the DSP56000 core, operating at an internal clock frequency of 275 MHz. The device delivers 275 MMACS performance, reaching 550 MMACS when utilizing the Enhanced Filter Coprocessor (EFCOP). It employs a 1.6 V core voltage with independent 3.3 V I/O power. Internal memory includes up to 192 K × 24 bits of RAM and a 31 K × 24 bits instruction cache, alongside a 192 × 24-bit bootstrap ROM.

Digital Signal Processor Dsp Procurement Notes

Verify that the specific ordering suffix corresponds to lead-free packaging requirements if RoHS compliance is mandatory. Confirm the package type matches the MAP-BGA specification. Ensure external decoupling capacitors are provided for all isolated power inputs (VCCQL, VCCQH, etc.) as specified in the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring large internal memory and high throughput. The EFCOP is suitable for accelerating general filtering tasks. Ensure the design supports the dual-voltage requirement of 1.6 V for the core and 3.3 V for I/O. Verify compatibility with the DSP56000 code base if migrating existing software.
