XAM1705BPTP3

Overview

The XAM1705BPTP3 is a microprocessor unit (MPU) belonging to the Sitara family, manufactured by Texas Instruments. It integrates an ARM926EJ-S core operating at a frequency of 375 MHz. The device features a 32-bit architecture and includes an embedded SDRAM controller for memory management. Connectivity options include Ethernet (10/100 Mbps), USB 2.0 with PHY, I2C, McASP, SPI, MMC/SD, and UART interfaces. It is housed in a 176-HLQFP package with exposed pads, measuring 24x24 mm, and supports I/O voltages of 1.8V and 3.3V.

Feature Summary

• Integrates an ARM926EJ-S processor core for embedded control applications
• Includes built-in peripherals such as Ethernet MAC and USB 2.0 PHY
• Features an internal SDRAM controller for direct memory interface

Applications

• Industrial automation controllers
• Medical instrumentation systems
• Smart home appliances

Procurement Notes

Verify the specific suffix 'D' or 'B' against the required temperature range and speed grade, as these denote distinct performance variants within the AM1705 series. Confirm the package type matches the PCB footprint requirements. Ensure the source document explicitly lists the part number as active or recommended for new designs to avoid obsolescence risks.

Selection Notes

Select this component when an ARM9-based solution with integrated connectivity is required for cost-sensitive embedded designs. Compare pin compatibility and peripheral availability against other Sitara processors if higher processing power or different interface counts are needed. Verify that the 375 MHz clock speed meets the real-time processing demands of the target application.

Part Context

This part is a variant of the AM1705 microprocessor line from Texas Instruments. It shares the same core architecture and peripheral set as other AM1705 models but may differ in manufacturing lot, speed binning, or specific package marking. It is designed for general-purpose embedded computing tasks requiring reliable ARM9 performance.

Replacement Considerations

Direct substitutes include AM1705BPTP3 and AM1705DPTP3, which share the same package and core specifications. Cross-referencing with the AM1806 series may be necessary if additional DSP capabilities or different peripheral configurations are required.
