Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM3354ZCZ80 is determined by strict alignment across the following critical parameters:

Core Architecture & Performance: All substitute parts must maintain the ARM® Cortex®-A8 core processor, 1-core configuration, and 32-bit bus width. Operating frequency may vary within the Sitara™ series.

Memory & Interface Support: Substitute parts must support identical RAM controller types (LPDDR, DDR2, DDR3, DDR3L), dual Gigabit Ethernet (10/100/1000Mbps), dual USB 2.0 with PHY, and the complete set of additional interfaces (CAN, I2C, McASP, McSPI, MMC/SD/SDIO, UART).

Graphics & Display Capabilities: Graphics acceleration and LCD/Touchscreen controller support must be present in all substitute parts.

Package & Environmental Compliance: All substitutes must use the 324-NFBGA (15x15) package format, operate within the 0°C to 90°C temperature range, maintain ROHS3 compliance, and support MSL 3 (168 Hours) moisture sensitivity specifications.

Security Features: Cryptography and Random Number Generator functionality must be retained.

Based on these criteria, the following parts qualify as substitutes:

• AM3354BZCZ80: Direct equivalent with identical electrical specifications and active product status
• AM3352BZCZ100: Higher-performance variant with 1.0GHz operating frequency, maintaining all other functional and interface requirements

Parameter Comparison

Engineering Selection Recommendations

AM3354BZCZ80 is the primary substitute for the obsolete AM3354ZCZ80. This part maintains identical electrical specifications, core architecture, and interface capabilities while offering active product status and improved supply chain availability. The transition from tube to tray packaging reflects current manufacturing standards. ROHS3 compliance and MSL 3 specifications are maintained, ensuring compatibility with existing design requirements and environmental regulations.

AM3352BZCZ100 serves as a performance-enhanced alternative within the Sitara™ family. Operating at 1.0GHz versus 800MHz, this variant provides increased processing capability while preserving all functional interfaces, memory controller support, and security features. The higher clock frequency results in improved computational throughput for applications requiring enhanced performance headroom. Active product status and robust supply availability support long-term production continuity.

Both substitute parts are manufactured by Texas Instruments and carry active product status, ensuring sustained availability and technical support. Selection between AM3354BZCZ80 and AM3352BZCZ100 depends on application performance requirements and thermal design considerations.

Frequently Asked Questions (FAQ)

Q: Can AM3354BZCZ80 be used as a direct replacement for AM3354ZCZ80?

A: Yes. AM3354BZCZ80 maintains identical electrical specifications, core processor architecture, operating frequency, memory controller support, interface configurations, and package format. The primary difference is active product status and packaging type (tray versus tube). No design modifications are required for electrical or functional compatibility.

Q: What is the primary advantage of AM3352BZCZ100 over AM3354BZCZ80?

A: AM3352BZCZ100 operates at 1.0GHz compared to 800MHz in AM3354BZCZ80, providing 25% higher clock frequency. All other functional parameters—core architecture, interfaces, memory controllers, security features, and package format—remain identical. This higher performance is suitable for applications requiring increased computational throughput.

Q: Are there thermal or power consumption differences between these parts?

A: The provided specifications do not include thermal or power consumption data. Consult Texas Instruments datasheets for detailed thermal and power characteristics specific to each part number.

Q: Do all three parts support the same memory types?

A: Yes. All three parts (AM3354ZCZ80, AM3354BZCZ80, and AM3352BZCZ100) support identical RAM controller types: LPDDR, DDR2, DDR3, and DDR3L.

Q: Is the 324-NFBGA (15x15) package identical across all three parts?

A: Yes. All three parts use the 324-NFBGA (15x15) package format with identical pin assignments and mechanical dimensions. PCB layout and footprint designs are directly compatible.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are ROHS3 compliant and carry MSL 3 (168 Hours) moisture sensitivity ratings. These certifications ensure compatibility with current environmental regulations and manufacturing standards.

Q: Why is AM3354ZCZ80 marked as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this part number. AM3354BZCZ80 and AM3352BZCZ100 represent the current active alternatives within the Sitara™ product line.
