DSP56303VL100B1

Digital Signal Processor Dsp Overview

The DSP56303VL100B1 is a 24-bit digital signal processor from the DSP56300 core family, manufactured by NXP USA Inc. (formerly Freescale Semiconductor). It delivers 100 MMACS performance using an internal 100 MHz clock operating at 3.0–3.6 volts. The device features a fully pipelined 24x24-bit parallel multiplier-accumulator with 56-bit accumulators and a barrel shifter. Internal memory includes up to 8 K x 24-bit RAM, configurable between program, instruction cache, X data, and Y data spaces. Key peripherals include a six-channel DMA unit, two Enhanced Synchronous Serial Interfaces (ESSI), a Host Interface (HI08), and a Serial Communication Interface (SCI).

Digital Signal Processor Dsp Feature Summary

• DSP56300 Core: 100 MMACS at 100 MHz with object code compatibility to the DSP56000 core.
• Memory Architecture: Configurable internal RAM totaling 8 K x 24 bits; supports external expansion to 256 K words for program and data spaces.
• Peripherals: Includes HI08 host interface, dual ESSI channels, SCI, triple timer module, and GPIOs.
• Power Management: Low-power CMOS design with Wait and Stop modes; operates down to 0 Hz (DC).

Digital Signal Processor Dsp Applications

• Multi-line voice/data/fax processing
• Video conferencing systems
• Audio applications
• General digital signal processing control

Digital Signal Processor Dsp Procurement Notes

Verify that the specific suffix 'VL100B1' corresponds to the lead-free MAP-BGA or TQFP package variant as defined in the datasheet revision history. Confirm voltage range compliance (3.0–3.6 V) and ensure adequate decoupling capacitors are selected for the multiple isolated power domains (VCCP, VCCQ, VCCA, etc.) specified in the electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select this component when a 24-bit architecture with high-performance MAC operations is required. Ensure the design accommodates the specific power domain isolation requirements (VCCQ vs. other rails) and provides sufficient external memory interfaces if the internal 8 K RAM is insufficient. Verify pin compatibility if migrating from older DSP56000 series devices, as packaging and pinouts differ significantly.

Digital Signal Processor Dsp Part Context

The DSP56303 belongs to the DSP56300 core family, which succeeded the DSP56000 series. It offers increased speed and power efficiency for telecommunications and multimedia products. The device integrates a Phase-Lock Loop (PLL) for clock generation and an OnCE hardware debugging module. It is designed to replace legacy designs requiring higher throughput while maintaining software compatibility with earlier 24-bit DSP architectures.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacement with DSP56002 is not supported due to differences in packaging (TQFP/PBGA vs. PQFP/TQFP) and voltage levels. Migration requires redesigning the PCB layout, power supply network, and potentially updating firmware to utilize new DMA and peripheral features.
