Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMS320VC5507ZHH is determined by strict equivalence across the following critical parameters:

• Processor Core Architecture: Fixed-point 16-bit DSP within the TMS320C55x series
• Clock Frequency: 200 MHz operational speed
• Memory Configuration: 128 kB on-chip RAM and 64 kB ROM
• Power Supply Requirements: 1.60V core voltage and 3.00V–3.30V I/O voltage
• Communication Interfaces: Host Interface, I2C, and McBSP support
• Package Specification: 179-LFBGA (12×12 mm) ball grid array
• Environmental Compliance: ROHS3 compliance and MSL 3 rating

The TMS320VC5507ZAY meets all these criteria and is classified as a direct substitute. Differences in packaging format (tray vs. standard packaging) and product status (active vs. obsolete) do not affect functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TMS320VC5507ZAY is a direct functional and electrical equivalent to the TMS320VC5507ZHH. Selection of the substitute part is supported by:

• Identical electrical specifications across all core parameters including processor architecture, clock frequency, memory configuration, and power supply requirements
• Identical package and pinout (179-LFBGA), ensuring direct PCB compatibility without layout modifications
• Active product status of the substitute, providing ongoing availability and manufacturing support compared to the obsolete main part
• Equivalent compliance certifications (ROHS3, MSL 3, REACH Unaffected), maintaining regulatory and environmental standards
• Identical interface support (Host Interface, I2C, McBSP), ensuring seamless integration with existing system designs

No design modifications, firmware updates, or system reconfiguration are required when substituting the TMS320VC5507ZAY for the TMS320VC5507ZHH.

Frequently Asked Questions (FAQ)

Q: Can the TMS320VC5507ZAY be used as a direct replacement for the TMS320VC5507ZHH without PCB modifications?

A: Yes. Both parts share identical package specifications (179-LFBGA), pinout, and electrical characteristics. No PCB layout changes are necessary.

Q: What is the difference between the TMS320VC5507ZHH and TMS320VC5507ZAY?

A: The primary differences are product status (obsolete vs. active) and packaging format (standard vs. tray). All functional and electrical parameters are identical.

Q: Are there any voltage compatibility concerns when substituting these parts?

A: No. Both parts operate at 1.60V core voltage and support 3.30V I/O operation. The TMS320VC5507ZHH supports an additional 3.00V I/O option, but the 3.30V specification is common to both and fully compatible.

Q: Does the TMS320VC5507ZAY maintain the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, carry MSL 3 rating (168 hours), and are REACH unaffected.

Q: Is firmware or software modification required when switching to the TMS320VC5507ZAY?

A: No. Identical processor architecture, instruction set, and interface specifications eliminate the need for firmware changes.

Q: What is the availability status of the TMS320VC5507ZAY?

A: The TMS320VC5507ZAY is an active product with current manufacturing support, providing reliable long-term availability compared to the obsolete TMS320VC5507ZHH.
