Substitute Part Grouping Explanation

Substitution eligibility for the AM1707CZKB4 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: 456MHz
• Package Type: 256-BGA (17x17)
• I/O Voltage Levels: 1.8V, 3.3V
• Operating Temperature Range: 0°C ~ 90°C (TJ)
• Integrated Peripherals: SDRAM controller, LCD interface, Ethernet (10/100Mbps), USB 1.1 and USB 2.0, I2C, McASP, SPI, MMC/SD, UART
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The AM1707DZKB4 meets all substitution criteria, maintaining identical electrical specifications, core architecture, clock frequency, package footprint, and peripheral integration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AM1707DZKB4 is the direct substitute for the AM1707CZKB4. Both parts are manufactured by Texas Instruments and share identical electrical, functional, and mechanical specifications. The AM1707DZKB4 carries Active product status, ensuring ongoing manufacturer support, availability, and compliance with current regulatory requirements. The AM1707CZKB4's Obsolete status makes the AM1707DZKB4 the appropriate selection for new designs and ongoing production requirements. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory obligations. The packaging difference (Tray for AM1707DZKB4 versus standard for AM1707CZKB4) does not affect electrical or functional compatibility and relates only to supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can the AM1707DZKB4 be used as a direct replacement for the AM1707CZKB4 in existing designs?

A: Yes. The AM1707DZKB4 is electrically and functionally identical to the AM1707CZKB4. Both parts feature the same ARM926EJ-S core, 456MHz clock frequency, 256-BGA package footprint, I/O voltage levels, operating temperature range, and integrated peripherals. No design modifications are required for substitution.

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

A: The AM1707CZKB4 is classified as Obsolete, indicating Texas Instruments has discontinued active production and support. The AM1707DZKB4 maintains Active status, ensuring continued availability, manufacturer technical support, and compliance with evolving regulatory standards. For new designs and long-term production, the Active part is the appropriate selection.

Q: Are there any package or handling differences between these parts?

A: The AM1707DZKB4 is supplied in Tray packaging, while the AM1707CZKB4 uses standard packaging. This distinction affects supply chain logistics and storage procedures but does not impact electrical performance, thermal characteristics, or PCB assembly compatibility. Both parts use identical 256-BGA (17x17) footprints.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the AM1707CZKB4 and AM1707DZKB4 are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level (MSL) is identical at 3 (168 Hours) for both parts. No compliance differences exist between the two parts.

Q: What interfaces and peripherals are supported by the AM1707DZKB4?

A: The AM1707DZKB4 integrates SDRAM controllers, LCD display interface, 10/100Mbps Ethernet (single port), USB 1.1 with PHY, USB 2.0 with PHY, I2C, McASP, SPI, MMC/SD, and UART interfaces. These specifications are identical to the AM1707CZKB4.
