DSP56303AG100

Digital Signal Processor Dsp Overview

The DSP56303AG100 is a 24-bit digital signal processor from the DSP56300 core family, manufactured by NXP Semiconductors. It delivers 100 MMACS performance using an internal 100 MHz clock at a nominal voltage of 3.3 V (operating range 3.0–3.6 V). The device features a fully pipelined architecture with a 24x24-bit parallel multiplier-accumulator and a 56-bit barrel shifter. Internal memory includes up to 8 K x 24-bit RAM, configurable between program, instruction cache, X data, and Y data spaces. It supports object code compatibility with the DSP56000 core and integrates peripherals such as two Enhanced Synchronous Serial Interfaces (ESSI), a Host Interface (HI08), and a Serial Communication Interface (SCI).

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status for lead-free variants, as Rev. 11 datasheets introduce lead-free packaging options. Check moisture sensitivity levels and shelf life requirements prior to assembly. Ensure supply chain stability as this component may be subject to end-of-life notifications.

Digital Signal Processor Dsp Selection Notes

Select the MAP-BGA package for high-density board layouts or the TQFP package for easier prototyping. Ensure power supply design accommodates multiple isolated rails (VCCQ, VCCA, VCCD, etc.) for noise reduction. Verify that external memory interfaces match the required address and data bus widths. Consider thermal dissipation requirements given the CMOS design specifications.

Digital Signal Processor Dsp Part Context

The DSP56303AG100 belongs to the DSP56300 family, which provides scalability for wireless, telecommunications, and multimedia products. It maintains software compatibility with the legacy DSP56000 core while offering enhanced speed and power efficiency. The AG suffix typically denotes specific temperature ranges or packaging variations within the Freescale/NXP portfolio.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in the provided documentation. Designers migrating from older DSP56000 series devices should account for architectural differences, particularly the increased pipeline depth and new instruction set extensions. Consult NXP for current alternative DSP solutions if availability is constrained.
