DSP56301AG80

Digital Signal Processor Dsp Overview

The DSP56301AG80 is a 24-bit Digital Signal Processor belonging to the DSP56300 core family. It delivers processing speeds of 66, 80, or 100 MIPS using an internal clock frequency of 66, 80, or 100 MHz at a supply voltage of 3.0–3.6 V. The architecture features a fully pipelined 24 x 24-bit parallel multiplier-accumulator with two 56-bit accumulators and a 56-bit barrel shifter. On-chip memory includes programmable Program RAM (up to 4096 x 24 bits), X Data RAM (up to 3072 x 24 bits), Y Data RAM (up to 3072 x 24 bits), and an instruction cache. Key peripherals include a 32-bit PCI/Universal Host Interface, two Enhanced Synchronous Serial Interfaces (ESSI), a Serial Communications Interface (SCI), a triple timer module, and up to 42 GPIO pins.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., AG80) against the official datasheet to confirm the maximum operating frequency and electrical characteristics. Ensure compatibility with the required 3.0–3.6 V power supply domain. Confirm package availability and pinout alignment for PCB design integration.

Digital Signal Processor Dsp Selection Notes

Select this component for general-purpose digital signal processing tasks requiring high throughput in multimedia and telecom sectors. Evaluate the programmable memory map to ensure sufficient on-chip storage for code and data before opting for external memory expansion. Consider the integrated PCI interface if host connectivity is required without additional logic buffers.

Digital Signal Processor Dsp Part Context

The DSP56301 is part of the broader DSP56300 core family, which shares object code compatibility with the legacy DSP56000 core. This lineage ensures software portability while offering enhanced performance through increased clock speeds and optimized addressing modes for digital signal processing workloads.

Digital Signal Processor Dsp Replacement Considerations

The DSP56301PB product brief does not list specific substitute part numbers. Engineers should consult the DSP56300 Family Manual for architectural comparisons within the same core family or evaluate newer NXP audio and vision processors for advanced feature sets.
