DSP56303VF100B1

Digital Signal Processor Dsp Overview

The DSP56303VF100B1 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 parallel multiplier-accumulator with a 56-bit barrel shifter and two 56-bit accumulators. Internal memory configuration includes up to 8 K x 24-bit RAM, distributed across program, X data, and Y data spaces, alongside a 192-word bootstrap ROM. It supports external memory expansion via Port A and integrates peripherals such as HI08, dual ESSI, SCI, triple timers, and a six-channel DMA unit.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'B1' against the official datasheet to confirm package type (TQFP or MAP-BGA) and lead-free status. The component is part of the DSP56300 family; ensure compatibility with existing design constraints regarding power domains and pin multiplexing. Check for end-of-life status or alternative sourcing options if current supply is limited.

Digital Signal Processor Dsp Selection Notes

Select this processor for applications requiring high-performance 24-bit fixed-point DSP capabilities with low power consumption. Ensure the design accommodates multiple isolated power domains (VCCP, VCCQ, VCCA, etc.) and ground planes as specified in the electrical characteristics. Consider the available internal RAM distribution when designing software for instruction caching and data buffering requirements.

Digital Signal Processor Dsp Part Context

The DSP56303 belongs to the DSP56300 core family of programmable CMOS DSPs. It serves as a successor to the DSP56000 series, offering increased speed and integrated peripherals while maintaining architectural compatibility. The device is designed for telecommunications and multimedia products, providing a balance of processing power and power efficiency through its optimized CMOS design and static operation down to 0 Hz.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacement with older models like the DSP56002 is not supported due to differences in packaging, power voltages, and peripheral configurations. When migrating from legacy designs, verify signal integrity and timing constraints for the new package type (TQFP or MAP-BGA).
