AM1705CPTP4 Equivalent & Substitute Parts

Part Overview

The AM1705CPTP4 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 functionality.

The AM1705CPTP4 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this processor architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1705CPTP4 is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: ARM926EJ-S (identical instruction set and performance characteristics)
• Core Count and Bus Width: 1 Core, 32-Bit (functional equivalence)
• Operating Frequency: 456MHz (identical clock speed)
• Package Type: 176-HLQFP (24x24) with exposed pad (identical footprint and pinout)
• I/O Voltage Levels: 1.8V, 3.3V (identical supply requirements)
• Operating Temperature Range: 0°C ~ 90°C (TJ) (identical thermal specifications)
• Mounting Technology: Surface Mount (identical assembly compatibility)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (identical regulatory status)

The AM1705DPTP4 meets all substitution criteria as a direct equivalent part. The primary distinction between the main part and substitute is the packaging format (tape and reel versus alternative packaging) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The AM1705DPTP4 is the direct substitute for the AM1705CPTP4. Both parts share identical electrical specifications, thermal characteristics, and physical packaging dimensions. The AM1705DPTP4 maintains Active product status with Texas Instruments, ensuring continued availability and support compared to the Obsolete classification of the AM1705CPTP4.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity. The substitution is electrically and mechanically transparent, requiring no design modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the AM1705DPTP4 replace the AM1705CPTP4 without PCB modifications?

A: Yes. Both parts feature identical 176-HLQFP (24x24) package geometry, pinout, and electrical specifications. No PCB layout changes are required.

Q: What is the difference between the AM1705CPTP4 and AM1705DPTP4?

A: The parts are electrically and functionally identical. The primary differences are packaging format (standard versus tray) and product status (Obsolete versus Active). The AM1705DPTP4 is the recommended choice for new production due to its Active status.

Q: Are there any voltage or thermal differences between these parts?

A: No. Both parts operate at identical I/O voltage levels (1.8V, 3.3V) and share the same operating temperature range (0°C ~ 90°C TJ) and moisture sensitivity level (MSL 4, 72 Hours).

Q: Does the AM1705DPTP4 meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance.

Q: Why is the AM1705CPTP4 classified as Obsolete?

A: Product status reflects Texas Instruments' lifecycle management. The AM1705DPTP4 remains in active production and is the recommended substitute for ongoing designs and production requirements.
