AM1705DPTP3

Overview

The AM1705DPTP3 is a microprocessor unit (MPU) from the Sitara family, manufactured by Texas Instruments. It features an ARM926EJ-S core operating at a maximum clock speed of 375MHz. The device is housed in a 176-HLQFP package with dimensions of 24x24 mm and includes a bare pad for thermal dissipation. It supports single-core, 32-bit processing with integrated SDRAM controller capabilities. The MPU operates within a temperature range of 0°C to 90°C TJ and utilizes 1.8V and 3.3V I/O voltages.

Feature Summary

• Integrates an ARM926EJ-S processor core with CP15 co-processor support for efficient control system applications.
• Includes built-in peripherals such as Ethernet MAC, USB 2.0 with PHY, and multiple serial interfaces including SPI, UART, and MMC/SD.
• Features an integrated SDRAM controller for direct memory access without external interface logic.

Applications

• Industrial automation controllers
• Smart home appliances and IoT gateways
• Medical instrumentation systems

Procurement Notes

Verify the specific ordering suffix DPTP3 to ensure the correct package type and temperature rating are selected. Confirm RoHS3 compliance status if required for environmental regulations. Check for any recent PCN notifications regarding material or marking changes before finalizing procurement plans.

Selection Notes

Select this component when an ARM9-based solution with integrated connectivity is required. Ensure the design accommodates the 176-pin HLQFP footprint and thermal requirements. Verify that the 375MHz performance meets application latency needs compared to higher-speed Cortex-A series alternatives.

Part Context

This part belongs to the Sitara embedded processor family, designed for cost-sensitive applications requiring moderate processing power. It bridges the gap between simple microcontrollers and high-performance application processors, offering integrated peripherals to reduce bill-of-materials complexity.

Replacement Considerations

Check for AM1705 variants with different package options or temperature ranges. Higher-performance Sitara models may require significant architectural redesign due to differences in core architecture and pin compatibility.
