AM3357ZCZD72 Equivalent & Substitute Parts

Part Overview

The AM3357ZCZD72 is an ARM Cortex-A8 Microprocessor IC from Texas Instruments' Sitara™ series, featuring a single 32-bit core operating at 720MHz with integrated multimedia and NEON™ SIMD co-processors. This embedded processor includes dual Gigabit Ethernet ports, dual USB 2.0 interfaces, LCD/touchscreen controllers, and comprehensive security features including cryptography and random number generation capabilities.

The AM3357ZCZD72 is classified as obsolete. Identifying equivalent and substitute parts is necessary to support ongoing system maintenance, design updates, and procurement continuity for applications requiring compatible ARM Cortex-A8 processing capabilities within the Sitara™ product family.

• RAM Controllers: LPDDR, DDR2, DDR3, DDR3L
• Graphics Acceleration: Yes
• Display & Interface Controllers: LCD, Touchscreen
• Ethernet: 10/100/1000Mbps (2)
• USB: USB 2.0 + PHY (2)
• Voltage - I/O: 1.8V, 3.3V
• Security Features: Cryptography, Random Number Generator
• Package / Case: 324-LFBGA
• Supplier Device Package: 324-NFBGA (15x15)
• Additional Interfaces: CAN, I2C, McASP, McSPI, MMC/SD/SDIO, UART
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Variable Parameters (Allowable Differences):

• Speed: May vary (720MHz baseline)
• Operating Temperature Range: May extend beyond -40°C ~ 90°C (TJ)
• Product Status: May differ (obsolete to active)
• ECCN Classification: May differ

The two substitute parts identified—AM3352BZCZD80 and AM3357BZCZA80—maintain all mandatory compatibility parameters while offering enhanced speed specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both AM3352BZCZD80 and AM3357BZCZA80 are qualified substitutes for the obsolete AM3357ZCZD72 based on functional and electrical compatibility.

AM3352BZCZD80 represents a cross-family substitute within the Sitara™ series. It maintains identical core architecture, interface configuration, and security capabilities while operating at 800MHz. This part is actively manufactured and available in production quantities (14,610 units in stock). ROHS3 compliance and REACH unaffected status align with the original part's regulatory requirements.

AM3357BZCZA80 represents a direct family upgrade within the AM3357 base product line. It maintains identical core architecture and interface configuration while operating at 800MHz and supporting an extended operating temperature range of -40°C to 105°C (compared to -40°C to 90°C for the original). This part is actively manufactured and available in production quantities (1,712 units in stock). ROHS3 compliance and REACH unaffected status align with the original part's regulatory requirements.

Selection between these substitutes depends on application-specific thermal requirements and inventory availability. The AM3357BZCZA80 is preferred for applications requiring extended temperature operation. The AM3352BZCZD80 is preferred for standard temperature range applications with higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can AM3352BZCZD80 and AM3357BZCZA80 be used interchangeably with AM3357ZCZD72?

A: Both parts are functionally compatible substitutes. They maintain identical core processor architecture, co-processor configuration, memory controller support, interface controllers, and security features. The 324-NFBGA (15x15) package footprint is identical, enabling direct PCB-level substitution. Differences in operating speed (800MHz vs. 720MHz) and operating temperature range do not prevent substitution in applications designed for the original part.

Q: What are the key differences between the two substitute parts?

A: AM3352BZCZD80 and AM3357BZCZA80 differ in base product family (AM3352 vs. AM3357) and maximum operating temperature. AM3357BZCZA80 supports -40°C to 105°C (TJ), while AM3352BZCZD80 supports -40°C to 90°C (TJ), matching the original part's temperature range. Both operate at 800MHz and maintain identical interface and security specifications.

Q: Are there any compliance or regulatory differences?

A: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original AM3357ZCZD72. ECCN classifications differ (5A992C for substitutes vs. 5A002A1 for the original), reflecting updated export control designations. Moisture sensitivity level remains MSL 3 (168 Hours) for all parts.

Q: What is the impact of the 80MHz speed increase?

A: The substitute parts operate at 800MHz compared to the original 720MHz. This represents an 11% increase in clock frequency. Applications designed for the AM3357ZCZD72 will operate at higher performance levels with the substitute parts. Thermal design and power delivery considerations may require evaluation for applications with tight thermal budgets.

Q: Are the packages identical?

A: Yes. All three parts use the 324-LFBGA package case with 324-NFBGA (15x15) supplier device package specification. PCB footprints, solder ball pitch, and mechanical dimensions are identical, enabling direct component substitution without PCB redesign.

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

A: Both parts are actively manufactured and available. AM3357BZCZA80 is recommended for applications requiring extended temperature operation beyond 90°C. AM3352BZCZD80 is recommended for standard temperature range applications. Inventory availability and procurement lead times should be evaluated for specific project timelines.
