VC55GPSGHH Equivalent & Substitute Parts

Part Overview

The VC55GPSGHH is a fixed-point digital signal processor (DSP) from Texas Instruments' TMS320C55x series, designed for embedded applications requiring 16-bit fixed-point processing. This device integrates a 200MHz clock rate with 256kB on-chip RAM and 64kB ROM, supporting multiple communication interfaces including Host Interface, I2C, and McBSP protocols.

The VC55GPSGHH is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. Substitute parts must maintain identical electrical specifications, memory configuration, interface capabilities, and thermal operating range to ensure functional compatibility without redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VC55GPSGHH is determined by strict equivalence across the following critical parameters:

• Processor Architecture & Performance: Series (TMS320C55x), Type (Fixed Point), Clock Rate (200MHz)
• Memory Configuration: On-Chip RAM (256kB), Non-Volatile Memory/ROM (64kB)
• Interface Compatibility: Host Interface, I2C, McBSP support
• Electrical Specifications: Voltage - I/O (3.00V, 3.30V), Voltage - Core (1.60V)
• Thermal Characteristics: Operating Temperature (-40°C ~ 85°C TC)
• Physical Package: 179-LFBGA, Surface Mount
• Environmental Compliance: Moisture Sensitivity Level 3 (168 Hours)

The substitute parts identified below meet all these criteria, enabling direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both TMS320VC5509AGBB and TMS320VC5509AZAY are active production alternatives to the obsolete VC55GPSGHH, with identical electrical and functional specifications.

TMS320VC5509AZAY is the preferred selection for new designs and production applications. This part maintains ROHS3 compliance and REACH unaffected status, aligning with current environmental regulations. Inventory availability of 50,200 units ensures supply chain continuity for volume production.

TMS320VC5509AGBB serves as a secondary alternative with 2,200 units in stock. This part is RoHS non-compliant and REACH affected, making it suitable only for applications where regulatory compliance is not a requirement or where legacy system maintenance is the primary objective.

Both parts are supplied in 179-NFBGA (12x12) packaging with tray packaging, compatible with standard surface-mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TMS320VC5509AGBB and TMS320VC5509AZAY be used interchangeably with VC55GPSGHH?

A: Yes. Both substitute parts maintain identical electrical specifications, memory configuration, interface protocols, thermal operating range, and physical package dimensions. Direct functional replacement is supported without circuit redesign.

Q: What is the difference between the two substitute parts?

A: The primary differences are product status, regulatory compliance, and inventory availability. TMS320VC5509AZAY is ROHS3 compliant and REACH unaffected with higher stock levels. TMS320VC5509AGBB is RoHS non-compliant and REACH affected. Both are electrically and functionally equivalent.

Q: Are there packaging differences between VC55GPSGHH and the substitute parts?

A: The main part uses 179-LFBGA packaging, while substitute parts use 179-NFBGA (12x12) packaging. Both are 179-ball BGA packages with identical pin assignments and footprints, compatible with the same PCB layouts and assembly equipment.

Q: What does MSL 3 (168 Hours) mean for handling and storage?

A: Moisture Sensitivity Level 3 requires that the component be stored in controlled humidity conditions and used within 168 hours of exposure to ambient conditions above 30°C and 85% relative humidity. All three parts share this specification.

Q: Which substitute part should be selected for new production designs?

A: TMS320VC5509AZAY is recommended for new designs due to ROHS3 compliance, REACH unaffected status, and superior inventory availability. This ensures regulatory alignment and supply chain stability for volume manufacturing.
