AM1705CPTP3 Equivalent & Substitute Parts

Part Overview

The AM1705CPTP3 is an ARM926EJ-S Microprocessor IC from Texas Instruments' Sitara™ series, featuring a single 32-bit core operating at 375MHz in a 176-HLQFP (24x24) surface mount package. This embedded processor integrates SDRAM controllers, 10/100Mbps Ethernet, USB 2.0 PHY, and multiple serial interfaces including I2C, McASP, SPI, MMC/SD, and UART.

The AM1705CPTP3 is classified as obsolete. Identifying equivalent substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1705CPTP3 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
• Co-Processor Configuration: System Control; CP15
• Memory Controller Type: SDRAM
• Peripheral Integration: 10/100Mbps Ethernet (1), USB 2.0 + PHY (1)
• Serial Interface Support: I2C, McASP, SPI, MMC/SD, UART
• I/O Voltage Levels: 1.8V, 3.3V
• Operating Temperature Range: 0°C ~ 90°C (TJ)
• Package Specification: 176-HLQFP (24x24) with exposed pad
• Compliance Standards: ROHS3, REACH Unaffected

Substitute parts must match all electrical and mechanical parameters. Packaging format differences (Tray vs. Tube) do not affect functional equivalence but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

The AM1705DPTP3 is a direct functional equivalent to the AM1705CPTP3. Both parts share identical electrical specifications, core architecture, peripheral integration, and package geometry. The primary distinction is product lifecycle status: the AM1705CPTP3 is obsolete, while the AM1705DPTP3 maintains active status with Texas Instruments.

For new designs or system updates, the AM1705DPTP3 is the appropriate selection due to its active product status and ongoing manufacturer support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent regulatory requirements.

The packaging format difference (Tray for AM1705CPTP3 vs. Tube for AM1705DPTP3) does not affect electrical or mechanical compatibility. This distinction impacts only procurement logistics and component handling procedures.

Frequently Asked Questions (FAQ)

Q: Can AM1705DPTP3 replace AM1705CPTP3 in existing designs?

A: Yes. The AM1705DPTP3 is electrically and mechanically equivalent. All core processor specifications, peripheral configurations, voltage levels, operating temperature range, and package dimensions are identical. Direct substitution is supported without design modification.

Q: What is the significance of the packaging format difference (Tray vs. Tube)?

A: Packaging format affects component handling, storage, and procurement procedures but does not impact electrical performance or mechanical fit. Tray packaging is typically used for automated assembly processes, while Tube packaging is common for manual handling and smaller quantity orders. Both formats contain the same component in the identical 176-HLQFP (24x24) package.

Q: Why is AM1705CPTP3 classified as obsolete?

A: Product obsolescence reflects Texas Instruments' lifecycle management. The AM1705DPTP3 maintains active status and represents the current production equivalent. For ongoing support and availability, the AM1705DPTP3 is the recommended selection.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level (MSL) 4 ratings. Regulatory and environmental compliance requirements are equivalent.

Q: What interfaces are supported by both parts?

A: Both AM1705CPTP3 and AM1705DPTP3 support I2C, McASP, SPI, MMC/SD, and UART serial interfaces, along with integrated 10/100Mbps Ethernet and USB 2.0 PHY connectivity. Interface functionality is identical across both parts.
