AM1707BZKB3 Equivalent & Substitute Parts

Part Overview

The AM1707BZKB3 is an ARM926EJ-S Microprocessor IC from Texas Instruments' Sitara™ series, featuring a single 32-bit core operating at 375MHz in a 256-BGA (17x17) package. This embedded processor integrates SDRAM controllers, LCD display interfaces, dual Ethernet (10/100Mbps), USB 1.1 and USB 2.0 PHY support, and additional interfaces including I2C, McASP, SPI, MMC/SD, and UART.

The AM1707BZKB3 carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing system support, design revisions, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1707BZKB3 is determined by strict equivalence across the following critical parameters:

• Core processor architecture and instruction set (ARM926EJ-S)
• Clock frequency (375MHz)
• Physical package specification (256-BGA, 17x17 dimensions)
• I/O voltage levels (1.8V, 3.3V)
• Operating temperature range (0°C ~ 90°C)
• Peripheral interface set (SDRAM controller, LCD controller, Ethernet, USB, I2C, McASP, SPI, MMC/SD, UART)
• Mounting technology (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The AM1707DZKB3 meets all substitution criteria as a direct equivalent part from the same manufacturer and series.

Parameter Comparison

Engineering Selection Recommendations

The AM1707DZKB3 is the direct substitute for the AM1707BZKB3. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The primary distinction is product lifecycle status: the AM1707BZKB3 is obsolete, while the AM1707DZKB3 maintains active status with Texas Instruments.

For new designs or system revisions, the AM1707DZKB3 is the appropriate selection. For legacy system maintenance where the AM1707BZKB3 is specified, the AM1707DZKB3 provides full functional and electrical equivalence with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can the AM1707DZKB3 replace the AM1707BZKB3 in existing designs?

A: Yes. The AM1707DZKB3 is electrically and functionally equivalent across all specified parameters. No PCB layout, schematic, or firmware modifications are necessary for substitution.

Q: Are there any differences in pin configuration between these parts?

A: No. Both parts use the identical 256-BGA (17x17) package with matching pin assignments, voltage levels, and interface specifications.

Q: What is the significance of the product status difference?

A: The AM1707BZKB3 is classified as obsolete, indicating Texas Instruments has discontinued active production and support. The AM1707DZKB3 maintains active status, ensuring ongoing availability, technical support, and compliance with current standards.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the AM1707BZKB3 and AM1707DZKB3 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the MSL rating, and why does it matter?

A: Both parts carry an MSL rating of 3 (168 Hours), indicating moisture sensitivity level 3. This specifies the maximum time the component can be exposed to moisture at specified temperature and humidity conditions before soldering. Proper handling and storage procedures must be followed to maintain component integrity.
