AM1810BZWTA3

Overview

The AM1810BZWTA3 is a Texas Instruments Sitara ARM926EJ-S microprocessor designed for PROFIBUS applications. It features a 375-MHz ARM core with 16KB instruction and data caches, plus 128KB on-chip RAM. Integrated peripherals include a Programmable Real-Time Unit Subsystem (PRUSS) for PROFIBUS, a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, SATA controller, LCD controller, and video interfaces. The device operates at 1.2V core voltage with 1.8V or 3.3V I/Os, housed in a 361-ball NFBGA package.

Feature Summary

• Integrated PRUSS subsystem dedicated to PROFIBUS link layer processing
• Supports DDR2 and Mobile DDR external memory controllers
• Includes SATA controller with hardware-assisted native command queuing
• Features universal parallel port for high-speed FPGA and data converter interfacing

Applications

• Industrial automation nodes requiring PROFIBUS connectivity
• Building automation systems
• Medical and healthcare equipment
• Set-top boxes and gaming devices

Procurement Notes

Verify the specific silicon revision indicated by the 'B' suffix against current datasheet errata. Confirm that the 361-ball NFBGA package dimensions match your PCB footprint requirements. Ensure power supply designs accommodate the specified 1.2V core and 1.8V/3.3V I/O voltage ranges for reliable operation.

Selection Notes

Select this component when PROFIBUS integration is required without external ASICs. It suits designs needing mixed analog/digital capabilities via its rich peripheral set including audio ports and video interfaces. Consider the 375-MHz performance limit and available on-chip memory when evaluating complex operating system support needs.

Part Context

This part belongs to the Texas Instruments Sitara AM18xx series of ARM-based microprocessors. It shares architectural similarities with the AM1808 but adds specialized PROFIBUS functionality through the PRUSS. The series targets industrial and consumer applications requiring robust connectivity and multimedia processing capabilities within a low-power form factor.
