Substitute Part Grouping Explanation

The AM3358BZCZ100 qualifies as a manufacturer-recommended substitute for the XAM3358AZCE based on the following substitution criteria:

Core Functional Equivalence: Both devices share the ARM® Cortex®-A8 processor architecture with identical 1 Core, 32-Bit configuration, multimedia co-processor support, and NEON™ SIMD capabilities.

Memory and Interface Compatibility: Both support identical RAM controller types (LPDDR, DDR2, DDR3, DDR3L), dual 10/100/1000Mbps Ethernet ports, dual USB 2.0 interfaces with PHY, LCD and touchscreen controllers, and the complete set of additional interfaces (CAN, I2C, McASP, McSPI, MMC/SD/SDIO, UART).

Electrical Specifications: Both devices operate with 1.8V and 3.3V I/O voltage levels and share the same 0°C to 90°C operating temperature range.

Security and Compliance: Both include cryptography and random number generator security features. Both carry MSL 3 (168 Hours) moisture sensitivity classification and REACH Unaffected status.

Key Differentiators: The AM3358BZCZ100 operates at 1.0GHz clock speed (not specified for XAM3358AZCE), features a larger 324-NFBGA (15x15) package, carries Active product status with ROHS3 compliance, and is available in Tray packaging with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The AM3358BZCZ100 is the manufacturer-recommended substitute for the obsolete XAM3358AZCE. Selection of the AM3358BZCZ100 is supported by the following engineering factors:

Product Status: The XAM3358AZCE is classified as Obsolete, while the AM3358BZCZ100 maintains Active product status, ensuring long-term availability and continued manufacturer support.

Regulatory Compliance: The AM3358BZCZ100 achieves ROHS3 compliance, whereas the XAM3358AZCE is RoHS non-compliant. This compliance improvement aligns with current environmental and regulatory requirements for electronic components.

Functional Equivalence: Both devices provide identical core processor architecture, co-processor capabilities, memory controller support, and peripheral interface configurations, ensuring functional compatibility in applications designed for the XAM3358AZCE.

Package Consideration: The AM3358BZCZ100 uses a 324-NFBGA (15x15) package compared to the 298-NFBGA (13x13) package of the XAM3358AZCE. PCB layout modifications are required to accommodate the larger package footprint and increased pin count.

Supply Availability: The AM3358BZCZ100 demonstrates significantly higher inventory availability (17,289 pieces) compared to the XAM3358AZCE (764 pieces), supporting production continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the AM3358BZCZ100 directly replace the XAM3358AZCE without PCB modifications?

A: No. The AM3358BZCZ100 uses a 324-NFBGA (15x15) package with 324 pins, while the XAM3358AZCE uses a 298-NFBGA (13x13) package with 298 pins. PCB layout redesign is required to accommodate the larger package footprint and modified pin assignments.

Q: Are the functional capabilities identical between these two parts?

A: Yes. Both devices share the same ARM® Cortex®-A8 processor core, NEON™ SIMD co-processor, memory controller types, peripheral interfaces, and security features. The primary differences are package size, clock speed specification, and product status.

Q: What is the significance of the RoHS compliance difference?

A: The AM3358BZCZ100 is ROHS3 compliant, meeting current environmental regulations for hazardous substance restrictions. The XAM3358AZCE is RoHS non-compliant. For new designs and applications subject to RoHS requirements, the AM3358BZCZ100 is the appropriate selection.

Q: Does the AM3358BZCZ100 operate at a higher clock speed?

A: The AM3358BZCZ100 is specified at 1.0GHz. The XAM3358AZCE does not have a specified clock speed in the provided data. Both devices support the same operating temperature range and I/O voltage levels.

Q: What packaging format is the AM3358BZCZ100 supplied in?

A: The AM3358BZCZ100 is supplied in Tray packaging, compared to the unspecified packaging format of the XAM3358AZCE. Both devices carry MSL 3 (168 Hours) moisture sensitivity classification.

Q: Are there any interface or connectivity differences between these parts?

A: No. Both devices provide identical Ethernet (dual 10/100/1000Mbps), USB (dual USB 2.0 + PHY), and additional interface support (CAN, I2C, McASP, McSPI, MMC/SD/SDIO, UART). LCD and touchscreen controller capabilities are also identical.
