AM1705CPTP3

Overview

The AM1705CPTP3 is a microprocessor unit (MPU) from the Texas Instruments Sitara family, built on an ARM926EJ-S core. It operates at a maximum clock frequency of 456 MHz and features a 32-bit data bus width. The device integrates an SDRAM controller and supports various peripheral interfaces including Ethernet, USB 2.0 with PHY, I2C, McASP, SPI, MMC/SD, and UART. It is housed in a 176-pin HLQFP package with dimensions of 24x24 mm and a height of 1.38 mm. The component functions within a junction temperature range of 0°C to +90°C.

Feature Summary

• Integrates an ARM926EJ-S processor core for embedded control applications
• Includes dedicated hardware support for SDRAM memory management
• Provides integrated Ethernet MAC and USB 2.0 PHY capabilities

Applications

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

Procurement Notes

Verify the specific suffix CPTP3 against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level (MSL 4) requirements for your assembly process. Check for obsolete status or lifecycle notices as availability may be limited. Ensure ESD handling procedures are followed during installation.

Selection Notes

Select this component when an ARM9-based solution with integrated connectivity is required. Compare against other Sitara variants if higher processing power or different interface counts are needed. Verify that the 456 MHz speed meets real-time processing requirements. Ensure the 176-pin package fits the PCB layout constraints.

Part Context

This part belongs to the Texas Instruments Sitara AM1705 series, designed for cost-sensitive embedded applications. It serves as a bridge between simple microcontrollers and complex application processors. The series targets markets requiring reliable processing with moderate performance and integrated peripherals.

Replacement Considerations

Check for direct substitutes like the AM1705DPTP3 or AM1705BPTP3. Verify pin compatibility and software register-level equivalence before substitution. Review any engineering change notices (ECNs) affecting the Sitara family.
