DSP56303VL100

Digital Signal Processor Dsp Overview

The DSP56303VL100 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 24x24-bit MAC, a 56-bit barrel shifter, and six DMA channels. Internal memory includes up to 8 K x 24-bit RAM and 192 words of bootstrap ROM. It supports external memory expansion via Port A and integrates peripherals such as HI08, two ESSI interfaces, SCI, and triple timers.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'VL' against the official datasheet to confirm lead-free packaging status and exact package type (TQFP or MAP-BGA). Confirm RoHS compliance details directly with the manufacturer documentation. Check for availability of the DSP56303UM user manual and related application notes required for development.

Digital Signal Processor Dsp Selection Notes

Select this component for fixed-point 24-bit DSP applications requiring high parallelism and low power. Ensure the design accommodates multiple isolated power domains (VCCP, VCCQ, VCCA, etc.) and corresponding ground planes. Verify that the external memory interface requirements align with the available address and data bus lines on Port A.

Digital Signal Processor Dsp Part Context

This part belongs to the DSP56300 family, which succeeded the DSP56000 series. It is designed for telecommunications and multimedia products. The device offers hardware debugging support via OnCE and JTAG interfaces. Documentation includes the Technical Data, User’s Manual, and Family Manual.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacement with older models like DSP56002 is not supported due to differences in packaging and pin mapping. Consider migration to newer NXP DSC families if advanced features are required, but verify software compatibility with the DSP56300 instruction set.
