MSC8256TAG1000B

Digital Signal Processor Dsp Overview

The MSC8256TAG1000B is a high-performance multicore digital signal processor based on StarCore SC3850 technology, manufactured using 45 nm CMOS SOI process. It integrates six programmable DSP cores operating at up to 1 GHz, delivering 48,000 MMACS total throughput. The device features a dual RISC QUICC Engine subsystem for packet processing, two DDR controllers supporting up to 2 GB per controller, and extensive connectivity including Serial RapidIO, PCI Express, Gigabit Ethernet, and TDM interfaces. Designed for medical imaging, aerospace, defense, and test applications, it offers scalability through pin compatibility with the MSC825x and MSC815x families.

• Aerospace and defense platforms
• Advanced test and measurement equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix TAG1000B against official NXP documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing board layouts due to the FC-PBGA 783-ball form factor. Confirm development tool availability, such as CodeWarrior DSP tools, for the design phase.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-density parallel processing and low power consumption via 45 nm SOI technology. Consider the pin-compatible MSC825x and MSC815x series for design flexibility. Evaluate the need for the integrated QUICC Engine if network protocol offloading is required alongside DSP tasks.

Digital Signal Processor Dsp Part Context

The MSC8256 belongs to the StarCore family of multicore DSPs from NXP (formerly Freescale). It is designed to replace single-core solutions by providing equivalent performance to a 6 GHz device in a smaller footprint. The architecture emphasizes high bandwidth and low latency through its CLASS fabric and multiple master buses.

Digital Signal Processor Dsp Replacement Considerations

The datasheet notes pin compatibility with other MSC825x and MSC815x DSP devices. Verify specific core speeds and memory configurations when substituting with variants within these families.
