Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1705BPTP3 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
• Package Type: 176-HLQFP (24x24) with exposed pad
• I/O Voltage Levels: 1.8V and 3.3V support
• Operating Temperature Range: 0°C ~ 90°C (TJ)
• Integrated Peripherals: SDRAM controller, 10/100Mbps Ethernet, USB 2.0 PHY, I2C, McASP, SPI, MMC/SD, UART
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The AM1705DPTP3 meets all electrical, mechanical, and functional equivalence criteria. The primary distinction between these parts is packaging format (Tray versus Tube) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The AM1705DPTP3 is a direct functional equivalent to the AM1705BPTP3. Both parts share identical electrical specifications, core architecture, operating frequency, peripheral integration, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The AM1705DPTP3 carries Active product status, ensuring continued manufacturer support and supply availability. The AM1705BPTP3 is classified as Obsolete, making the AM1705DPTP3 the appropriate selection for new designs and ongoing production support.

The only non-functional difference is packaging format: AM1705BPTP3 is supplied in Tray format, while AM1705DPTP3 is supplied in Tube format. This distinction does not affect electrical performance, thermal characteristics, or mechanical compatibility in PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Are AM1705BPTP3 and AM1705DPTP3 electrically identical?

A: Yes. Both parts feature the ARM926EJ-S core, 375MHz operating frequency, identical I/O voltage levels (1.8V, 3.3V), matching operating temperature range (0°C ~ 90°C TJ), and equivalent peripheral integration including SDRAM controller, 10/100Mbps Ethernet, USB 2.0 PHY, and communication interfaces (I2C, McASP, SPI, MMC/SD, UART).

Q: What is the difference between Tray and Tube packaging?

A: Tray and Tube are packaging and shipping formats that do not affect component electrical performance or mechanical compatibility. Tray packaging is typically used for higher-volume shipments, while Tube packaging is standard for smaller quantities. Both formats accommodate the 176-HLQFP (24x24) surface mount package.

Q: Can AM1705DPTP3 replace AM1705BPTP3 in existing designs?

A: Yes. The AM1705DPTP3 is a direct substitute. No design modifications, PCB layout changes, or firmware adjustments are required. The parts are pin-compatible and functionally equivalent.

Q: Why is AM1705BPTP3 marked as Obsolete?

A: Product status reflects manufacturer lifecycle decisions. The Obsolete designation indicates that Texas Instruments has discontinued active production and support for this specific part number. The AM1705DPTP3, with Active status, represents the current equivalent offering.

Q: Are compliance certifications identical between these parts?

A: Yes. Both AM1705BPTP3 and AM1705DPTP3 are ROHS3 Compliant and REACH Unaffected, with matching Moisture Sensitivity Level (MSL) ratings of 4 (72 Hours).
