TMS320VC5441GGU Description

The TMS320VC5441GGU is a high-performance fixed-point digital signal processor (DSP) from Texas Instruments' TMS320C54x series. Designed for embedded signal processing applications, it operates at a 133MHz clock rate with a 1.60V core voltage and 3.30V I/O voltage, balancing power efficiency and performance. The DSP features 1.25MB of on-chip RAM for high-speed data processing but relies on external non-volatile memory for program storage. Packaged in a 169-BGA form factor, it is surface-mountable and compliant with ROHS3 and REACH environmental standards.

TMS320VC5441GGU Features

• High-Speed Processing: 133MHz fixed-point architecture optimized for real-time signal processing.
• Low Power Consumption: 1.60V core voltage reduces energy usage in power-sensitive applications.
• Rich Interfaces: Includes a Host Interface and Multichannel Buffered Serial Port (McBSP) for flexible connectivity.
• Large On-Chip RAM: 1.25MB enables efficient handling of complex algorithms without external memory bottlenecks.
• Industrial Robustness: Operates across 0°C to 85°C (TC), suitable for harsh environments.
• Obsolete Status: While no longer in production, it remains a reliable choice for legacy systems.
