TMS320VC5507GHH Equivalent & Substitute Parts

Part Overview

The TMS320VC5507GHH is a fixed-point digital signal processor (DSP) from Texas Instruments' TMS320C55x series, designed for embedded applications requiring 16-bit signal processing at 200MHz clock rate. This device integrates 64kB ROM and 128kB on-chip RAM with multiple communication interfaces including Host Interface, I2C, and McBSP.

The TMS320VC5507GHH carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term production requirements for systems utilizing this DSP architecture.

Substitute Part Grouping Explanation

Substitute parts for the TMS320VC5507GHH are identified based on strict equivalence across the following critical parameters:

• Manufacturer: Texas Instruments
• Series: TMS320C55x
• Type: Fixed Point DSP
• Clock Rate: 200MHz
• Memory Configuration: ROM (64kB) and On-Chip RAM (128kB)
• Interface Set: Host Interface, I2C, McBSP
• Core Voltage: 1.60V
• Operating Temperature Range: -40°C ~ 85°C (TC)
• Package / Case: 179-LFBGA
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 3 (168 Hours)

Two substitute parts meet these functional and electrical equivalence criteria: TMS320VC5507GBB and TMS320VC5507ZAY. Both devices maintain identical core specifications, memory architecture, interface capabilities, and thermal operating parameters as the main part.

Parameter Comparison

Engineering Selection Recommendations

Both TMS320VC5507GBB and TMS320VC5507ZAY provide functional equivalence to the obsolete TMS320VC5507GHH across all core DSP specifications and electrical parameters.

TMS320VC5507ZAY is the preferred substitute when regulatory compliance is a primary consideration. This part maintains ROHS3 compliance and REACH unaffected status, matching the original part's compliance profile. It is supplied in Tray packaging and has 836 units in current inventory.

TMS320VC5507GBB is functionally equivalent but carries RoHS non-compliant and REACH affected designations. This part is available in higher inventory (3100 units) and may be suitable for applications where compliance requirements differ from the original specification. The supplier device package designation differs (179-NFBGA versus 179-LFBGA), requiring verification of mechanical compatibility in the target assembly.

Both substitute parts are currently in active production status, ensuring long-term availability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Are TMS320VC5507GBB and TMS320VC5507ZAY electrically interchangeable with TMS320VC5507GHH?

A: Yes. Both substitute parts maintain identical core voltage (1.60V), clock rate (200MHz), memory configuration (64kB ROM, 128kB RAM), interface set (Host Interface, I2C, McBSP), and operating temperature range (-40°C ~ 85°C). Electrical functionality is equivalent.

Q: What is the difference between the I/O voltage specifications?

A: The TMS320VC5507GHH supports dual I/O voltage levels (3.00V and 3.30V), while both substitute parts support 3.30V I/O only. Applications requiring 3.00V I/O operation must evaluate system-level voltage regulation compatibility.

Q: Do the package designations affect physical compatibility?

A: The main part specifies 179-LFBGA packaging, while substitutes list 179-NFBGA. Both are 179-ball BGA packages in 12x12mm form factor. Verify PCB footprint and assembly process compatibility with your manufacturing partner, as subtle differences in ball placement or solder pad geometry may exist between LFBGA and NFBGA variants.

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

A: TMS320VC5507ZAY is recommended for new designs requiring regulatory compliance alignment with the original part. TMS320VC5507GBB is suitable when compliance requirements differ or when higher inventory availability is prioritized.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: Both substitute parts carry MSL 3 (168 Hours), identical to the main part. This specifies maximum floor-life exposure before reflow soldering. Storage and handling procedures must follow MSL 3 requirements for all three parts.
