Substitute Part Grouping Explanation

Substitution eligibility for the AM1707BZKB4 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 + USB 2.0, I2C, McASP, SPI, MMC/SD, UART
• Compliance Standards: ROHS3, REACH Unaffected

Parts meeting all these criteria are classified as direct functional equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

The AM1707DZKB4 is a direct functional equivalent to the AM1707BZKB4. Both parts share identical electrical specifications, core architecture, operating frequency, package configuration, and peripheral integration.

The primary distinction is product lifecycle status: the AM1707BZKB4 is classified as Obsolete, while the AM1707DZKB4 maintains Active status. For new designs or systems requiring long-term component availability, the AM1707DZKB4 is the appropriate selection. Both parts maintain equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected) and identical moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can AM1707DZKB4 replace AM1707BZKB4 without PCB redesign?
