Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1808BZWT3 is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: ARM926EJ-S
• Core Count and Bus Width: 1 Core, 32-Bit
• Operating Frequency: 375MHz
• Memory Controller Support: LPDDR and DDR2
• Peripheral Integration: Ethernet (10/100Mbps), SATA (3Gbps), USB (1.1 and 2.0), LCD controller
• Interface Support: I2C, McASP, McBSP, SPI, MMC/SD, UART
• Package Specification: 361-NFBGA (16x16)
• Voltage Levels: 1.8V and 3.3V I/O
• Operating Temperature Range: 0°C ~ 90°C (TJ)
• Compliance Standards: ROHS3, REACH Unaffected

The AM1808EZWT3 meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The AM1808EZWT3 is the direct substitute for the AM1808BZWT3. Both parts share identical electrical specifications, core architecture, peripheral integration, and compliance certifications. The AM1808EZWT3 carries Active product status, ensuring ongoing manufacturer support and supply chain availability, whereas the AM1808BZWT3 is classified as Obsolete.

For new designs or systems requiring component replacement, the AM1808EZWT3 is the appropriate selection. The packaging difference (Tray versus Bulk) reflects standard distribution configurations and does not affect functional or electrical compatibility. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the AM1808EZWT3 directly replace the AM1808BZWT3 in existing designs?

A: Yes. The AM1808EZWT3 is electrically and functionally identical to the AM1808BZWT3. All core specifications, peripheral interfaces, voltage levels, operating temperature range, and package dimensions are equivalent. No design modifications are required for substitution.

Q: What is the significance of the product status difference between these parts?

A: The AM1808BZWT3 is classified as Obsolete, indicating that Texas Instruments no longer manufactures this part. The AM1808EZWT3 maintains Active status, meaning it is currently in production and available through authorized distribution channels. For long-term supply chain reliability, the AM1808EZWT3 is the recommended choice.

Q: Are there any differences in the package specifications?

A: Both parts use the 361-NFBGA (16x16) package with 361-LFBGA case designation. The only difference is the packaging configuration: the AM1808BZWT3 is supplied in Bulk format, while the AM1808EZWT3 is supplied in Tray format. This distinction affects handling and storage but does not impact electrical performance or physical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AM1808BZWT3 and AM1808EZWT3 are ROHS3 Compliant and REACH Unaffected. They share identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), ensuring equivalent handling and storage requirements.

Q: What interfaces and peripherals are supported by the substitute part?

A: The AM1808EZWT3 supports all interfaces present in the AM1808BZWT3: I2C, McASP, McBSP, SPI, MMC/SD, and UART. Peripheral integration includes 10/100Mbps Ethernet, SATA 3Gbps, USB 1.1 and USB 2.0 with integrated PHY, and LCD display controller. Memory controller support includes LPDDR and DDR2.
