MSC8252TAG1000B

Digital Signal Processor Dsp Overview

The MSC8252TAG1000B is a dual-core digital signal processor based on the StarCore SC3850 architecture, manufactured by NXP Semiconductors. It integrates two SC3850 DSP subsystems operating at a maximum clock frequency of 1 GHz. Each core features 32 Kbyte L1 instruction cache, 32 Kbyte L1 data cache, and a unified 512 Kbyte L2 cache configurable as M2 memory. The device includes 1056 Kbyte shared M3 memory, two DDR controllers supporting up to 2 Gbyte total capacity with DDR2/DDR3, and a QUICC Engine subsystem with dual RISC processors for communication offloading. It utilizes 45 nm SOI CMOS technology and is housed in a 783-ball FC-PBGA package.

Digital Signal Processor Dsp Feature Summary

• Dual SC3850 DSP cores with 1 GHz operation, 32 KB L1 I/D caches, and 512 KB L2 cache per core
• QUICC Engine subsystem featuring dual RISC processors, 48 KB multi-master RAM, and support for two Gigabit Ethernet interfaces
• High-speed serial interface supporting two Serial RapidIO (up to 3.125 Gbaud), one PCI Express (x1/x2/x4), and two SGMII interfaces
• Two DDR controllers supporting DDR2/DDR3 with up to 2 Gbyte total capacity and ECC/EDC support

Digital Signal Processor Dsp Applications

• Telecommunications base station processing
• Digital radio and software-defined radio systems
• Network infrastructure equipment requiring high-throughput signal processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'TAG' against the manufacturer's official documentation to confirm temperature range and packaging details. Confirm current product lifecycle status, as this component may be obsolete or subject to last-time buy restrictions. Ensure compatibility with existing board designs regarding the 783-ball FC-PBGA footprint and power supply requirements.

Digital Signal Processor Dsp Selection Notes

Select this component when dual-core high-performance DSP processing is required alongside integrated communication capabilities. The inclusion of the QUICC Engine allows for offloading network scheduling tasks from the DSP cores. Consider the 45 nm SOI process for low-power operation and the availability of multiple high-speed serial interfaces for system connectivity.

Digital Signal Processor Dsp Part Context

The MSC8252 belongs to the StarCore family of digital signal processors designed for demanding real-time processing applications. It combines high-performance DSP execution with embedded communication engines, distinguishing it from general-purpose microprocessors or standalone DSPs lacking integrated network interfaces.
