TMS320VC5504ZCH Equivalent & Substitute Parts

Part Overview

The TMS320VC5504ZCH is a fixed-point digital signal processor (DSP) from Texas Instruments' TMS320C55x series, housed in a 196-pin NFBGA package. This embedded integrated circuit is designed for applications requiring real-time signal processing with support for multiple communication interfaces including I2C, I2S, SPI, UART, and USB. The device operates at 100MHz with 256kB on-chip RAM and 128kB ROM, making it suitable for audio, telecommunications, and industrial control applications.

The TMS320VC5504ZCH carries an Obsolete product status. Identifying equivalent substitute parts is essential for system redesign, long-term production planning, and ensuring supply chain continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS320VC5504ZCH is determined by strict alignment across the following critical parameters:

Core Compatibility Criteria:

• Same base product series (TMS320C55x)
• Identical clock rate (100MHz)
• Matching on-chip RAM capacity (256kB)
• Matching ROM capacity (128kB)
• Identical package type (196-LFBGA / 196-NFBGA 10x10)
• Compatible voltage specifications (core and I/O)
• Same mounting technology (Surface Mount)

The TMS320C5504AZCH10 qualifies as a direct substitute because it maintains all core electrical and mechanical specifications while offering an Active product status and expanded interface support. Both devices share the same TMS320C55x architecture, identical memory configuration, matching clock frequency, and compatible packaging. The substitute part provides enhanced interface options (EBI/EMI, MMC/SD support) and flexible core voltage selection (1.05V or 1.30V) while preserving full backward compatibility with existing designs.

Engineering Selection Recommendations

The TMS320C5504AZCH10 is the qualified substitute for the obsolete TMS320VC5504ZCH based on the following engineering criteria:

Product Status Alignment: The substitute part maintains Active product status with Texas Instruments, ensuring continued availability, technical support, and compliance documentation. The original part's Obsolete designation creates supply risk and limits access to updated datasheets and application notes.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and consumer applications. Identical MSL ratings (3, 168 Hours) ensure equivalent moisture handling and storage protocols.

Electrical & Mechanical Compatibility: Identical core specifications—100MHz clock rate, 256kB RAM, 128kB ROM, and 196-NFBGA packaging—guarantee pin-for-pin compatibility and functional equivalence. The substitute's flexible core voltage option (1.05V or 1.30V) provides design flexibility while maintaining compatibility with existing 1.30V implementations.

Extended Operating Range: The substitute part's expanded temperature range (-10°C to 70°C versus 0°C to 70°C) offers improved performance margin for applications operating in lower ambient conditions.

Frequently Asked Questions (FAQ)

Q: Is the TMS320C5504AZCH10 a direct pin-for-pin replacement for the TMS320VC5504ZCH?

A: Yes. Both devices use the 196-NFBGA (10x10) package with identical pinout. The substitute maintains all core electrical specifications including clock rate, memory configuration, and voltage requirements, enabling direct board-level substitution without layout modifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Obsolete versus Active), operating temperature range (-10°C to 70°C for the substitute versus 0°C to 70°C for the original), and expanded interface support in the substitute (EBI/EMI, MMC/SD). The substitute also offers flexible core voltage selection (1.05V or 1.30V).

Q: Can I use the substitute part in existing designs without firmware changes?

A: The substitute part maintains full architectural compatibility with the TMS320C55x instruction set and memory organization. Existing firmware compiled for the original part will execute on the substitute without modification, provided the design operates within the specified voltage and temperature parameters.

Q: Are there any supply chain advantages to using the substitute part?

A: Yes. The TMS320C5504AZCH10 carries Active product status with higher current inventory availability (1112 pieces in stock versus 848 for the original). Active status ensures long-term supply continuity and access to technical documentation.

Q: What packaging format is available for the substitute part?

A: The TMS320C5504AZCH10 is supplied in Tray packaging, suitable for automated assembly processes. Both parts share identical 196-NFBGA (10x10) package geometry and MSL rating.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the TMS320VC5504ZCH and TMS320C5504AZCH10 are ROHS3 compliant and REACH Unaffected, meeting current environmental and hazardous substance restrictions for industrial and commercial applications.
