Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DM355SDZCEA216 is determined by strict alignment of the following parameters:

• Processor Series & Architecture: Must be TMS320DM3x DaVinci™ series to ensure instruction set compatibility
• Clock Rate: Must match 216MHz for timing-critical applications
• Memory Configuration: On-chip RAM (56kB) and ROM (8kB) must be identical
• Voltage Specifications: Core voltage (1.30V) and I/O voltage (1.8V, 3.3V) must match exactly
• Interface Set: ASP, I2C, SPI, UART, and USB interfaces must all be present
• Package Footprint: 337-LFBGA (13x13) ensures mechanical and electrical compatibility
• Compliance Standards: RoHS3 compliance and REACH status must be maintained

The identified substitute part TMS320DM355DZCE216 meets all these criteria while differing only in packaging format (Tube vs. Tray) and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The TMS320DM355DZCE216 is a direct functional equivalent to the DM355SDZCEA216 for applications within the overlapping operating temperature range of 0°C to 85°C. Both parts maintain identical electrical specifications, memory configurations, interface capabilities, and compliance certifications (ROHS3, REACH Unaffected).

Selection between these parts should be based on:

• Temperature Requirements: If your application requires operation below 0°C or above 85°C, the DM355SDZCEA216 with its extended -40°C to 100°C range is necessary. For standard industrial and commercial temperature ranges (0°C to 85°C), the TMS320DM355DZCE216 is suitable.

• Packaging and Logistics: The DM355SDZCEA216 is supplied in Tray packaging, while TMS320DM355DZCE216 is supplied in Tube packaging. Select based on your assembly process requirements and inventory handling procedures.

• Product Status and Supply: Both parts are end-of-life. The DM355SDZCEA216 is in Last Time Buy status with 1119 units in stock. The TMS320DM355DZCE216 is marked Not For New Designs with 1900 units available. For new designs, neither part is recommended; however, for legacy system support or existing design continuations, either part provides functional equivalence within their respective operating parameters.

• Compliance Verification: Both parts maintain identical RoHS3 compliance and REACH status, ensuring regulatory requirements are met for either selection.

Frequently Asked Questions (FAQ)

Q: Can TMS320DM355DZCE216 be used as a direct replacement for DM355SDZCEA216 in all applications?

A: The TMS320DM355DZCE216 is a direct functional replacement for applications operating within 0°C to 85°C. If your design requires the extended temperature range (-40°C to 100°C) of the DM355SDZCEA216, the substitute part is not suitable. All other electrical and mechanical parameters are identical.

Q: What is the difference between Tray and Tube packaging?

A: Tray packaging (DM355SDZCEA216) and Tube packaging (TMS320DM355DZCE216) differ in physical presentation and handling. Tray packaging typically accommodates higher-volume automated assembly processes, while Tube packaging is suited for lower-volume or manual assembly operations. The electrical and functional characteristics of the component are identical regardless of packaging format.

Q: Are there any other substitute parts available for the DM355SDZCEA216?

A: Based on the provided specifications, TMS320DM355DZCE216 is the identified substitute that meets all core electrical and mechanical parameters. No additional substitutes are listed.

Q: What does "Last Time Buy" and "Not For New Designs" mean?

A: Last Time Buy indicates the DM355SDZCEA216 is in final production phase with limited remaining inventory. Not For New Designs indicates the TMS320DM355DZCE216 has been discontinued and should not be used in new product development. Both designations reflect end-of-life status; however, existing designs may continue to use either part within their respective operating specifications.

Q: Are both parts RoHS3 compliant?

A: Yes, both DM355SDZCEA216 and TMS320DM355DZCE216 are ROHS3 Compliant and REACH Unaffected, ensuring compliance with current environmental and regulatory standards.

Q: What is the Moisture Sensitivity Level (MSL) and why does it matter?

A: Both parts have MSL 3 (168 Hours), indicating they require controlled humidity storage and handling. MSL 3 means the component can be exposed to ambient conditions (30% to 85% relative humidity) for a maximum of 168 hours before soldering. Proper storage in dry-pack conditions is required to maintain component reliability.
