Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS320DM365ZCEZ is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 338-LFBGA (13x13) surface mount package to ensure PCB layout and mechanical fit
• Interface Support: Both parts must provide EBI/EMI, Ethernet, I2C, McBSP, SPI, UART, and USB interfaces for functional equivalence
• Memory Configuration: On-chip RAM (56kB) and ROM (16kB) must match to maintain software compatibility
• Voltage Specifications: Core voltage and I/O voltage ranges must be compatible with existing power delivery and signal conditioning circuits
• Operating Temperature Range: Both parts must support 0°C ~ 85°C operation
• Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained

The TMS320DM365ZCE21 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The TMS320DM365ZCE21 is the qualified substitute for the TMS320DM365ZCEZ based on the following engineering criteria:

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in manufacturing and deployment.

Product Status Advantage: The TMS320DM365ZCE21 carries Active product status with higher inventory availability (2200 pcs in stock versus 926 pcs), providing superior long-term supply security compared to the Last Time Buy status of the original part.

Functional Equivalence: Identical package, memory configuration, interface set, and operating temperature range ensure direct functional compatibility in existing designs.

Performance Consideration: The substitute operates at 216MHz versus the original 300MHz clock rate. This represents a 28% reduction in processor speed. Applications requiring the full 300MHz performance specification must evaluate whether the lower clock rate meets throughput requirements.

Power Delivery Adjustment: The substitute requires 1.20V core voltage versus 1.35V for the original part. Power supply circuits may require recalibration to accommodate this lower voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the TMS320DM365ZCE21 be used as a direct drop-in replacement?

A: The TMS320DM365ZCE21 is mechanically and functionally compatible due to identical package, memory, and interface specifications. However, the reduced clock rate (216MHz vs. 300MHz) and lower core voltage (1.20V vs. 1.35V) require evaluation of system performance requirements and power delivery circuit adjustment.

Q: What is the primary difference between these two parts?

A: The main differences are clock rate and core voltage. The TMS320DM365ZCEZ operates at 300MHz with 1.35V core voltage, while the TMS320DM365ZCE21 operates at 216MHz with 1.20V core voltage. All other electrical and mechanical parameters remain identical.

Q: Why is the original part in Last Time Buy status?

A: Last Time Buy status indicates Texas Instruments has discontinued production of the TMS320DM365ZCEZ. The TMS320DM365ZCE21, with Active product status, represents the current production alternative within the same DaVinci™ series.

Q: Are there any interface compatibility concerns?

A: No. Both parts provide identical interface support: EBI/EMI, Ethernet, I2C, McBSP, SPI, UART, and USB. Signal voltage levels (1.8V and 3.3V I/O) are also identical.

Q: What packaging considerations apply to both parts?

A: Both parts use the 338-LFBGA (13x13) surface mount package with MSL rating 3 (168 hours). PCB layout, solder reflow profiles, and moisture handling procedures remain unchanged between the two parts.

Q: Does the lower core voltage affect system design?

A: The 1.20V core voltage requirement for the substitute may necessitate adjustment of the core power supply circuit. Verify that the power delivery network can maintain voltage regulation within the specified tolerance at the lower voltage level.
