AM1705CPTPD4 Equivalent & Substitute Parts

Part Overview

The AM1705CPTPD4 is an ARM926EJ-S Microprocessor IC from Texas Instruments' Sitara™ series, featuring a single 32-bit core operating at 456MHz in a 176-HLQFP (24x24) package. This embedded processor integrates system control, SDRAM controllers, and multiple communication interfaces including Ethernet (10/100Mbps), USB 2.0, I2C, SPI, and UART.

The AM1705CPTPD4 is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new design implementations where this processor meets functional requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the AM1705CPTPD4 is determined by strict equivalence across the following critical parameters:

• Core Architecture: ARM926EJ-S processor
• Core Configuration: 1 Core, 32-Bit
• Operating Frequency: 456MHz
• Co-Processor Support: System Control and CP15
• Memory Controller: SDRAM support
• Peripheral Integration: Ethernet (10/100Mbps), USB 2.0 with PHY, I2C, McASP, SPI, MMC/SD, UART
• Electrical Specifications: I/O voltage levels (1.8V, 3.3V)
• Thermal Range: -40°C to 90°C (TJ)
• Package Compatibility: 176-HLQFP (24x24) with exposed pad
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The AM1705DPTPD4 meets all substitution criteria as a direct equivalent with identical electrical, functional, and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AM1705DPTPD4 is the direct substitute for the obsolete AM1705CPTPD4. Both parts are manufactured by Texas Instruments and share identical electrical, functional, and mechanical specifications. The primary distinction is product status: the AM1705CPTPD4 is obsolete, while the AM1705DPTPD4 is active and currently available in production quantities.

For new designs or system replacements, the AM1705DPTPD4 is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The identical package footprint (176-HLQFP 24x24) and pinout enable direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AM1705DPTPD4 replace the AM1705CPTPD4 in existing designs?

A: Yes. The AM1705DPTPD4 is electrically and mechanically identical to the AM1705CPTPD4. Both parts feature the same ARM926EJ-S core, 456MHz clock speed, peripheral integration, I/O voltage levels, and 176-HLQFP package. Direct substitution is supported without design changes.

Q: What is the difference between these two part numbers?

A: The parts are functionally equivalent. The primary difference is product lifecycle status: AM1705CPTPD4 is obsolete, while AM1705DPTPD4 is active. The AM1705DPTPD4 is the recommended selection for current procurement and new applications.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 176-HLQFP (24x24) package with exposed pad. PCB footprints, pinout, and thermal characteristics are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AM1705CPTPD4 and AM1705DPTPD4 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 4 (72 Hours) for both parts.

Q: What interfaces are supported by these processors?

A: Both parts integrate Ethernet (10/100Mbps), USB 2.0 with PHY, I2C, McASP, SPI, MMC/SD, and UART interfaces. SDRAM memory controllers and system control coprocessor (CP15) are included.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 90°C junction temperature (TJ), suitable for industrial and extended temperature applications.
