AM1808BZWTT3

Overview

The AM1808BZWTT3 is an ARM926EJ-S microprocessor from Texas Instruments, operating at 375 MHz with a 1.2 V core voltage. It features a 32-bit RISC architecture with 16 KB instruction and data caches, 128 KB on-chip RAM, and a Programmable Real-Time Unit Subsystem (PRUSS). Key peripherals include a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, SATA controller, and video interfaces. The device is housed in a 361-ball NFBGA package.

Feature Summary

• Integrates a programmable real-time unit subsystem for deterministic control tasks alongside the main ARM processor.
• Includes dedicated hardware accelerators for high-speed connectivity such as Ethernet MAC and SATA controllers.
• Supports multiple memory interfaces including DDR2/mDDR SDRAM and asynchronous external memory.
• Features comprehensive multimedia capabilities with LCD controller and video port interface.

Applications

• Set Top Box
• Industrial Automation

Procurement Notes

Verify the specific suffix 'T3' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the silicon revision matches project requirements, as performance characteristics may vary between revisions. Cross-reference the part number with the latest datasheet to confirm availability status and any potential obsolescence notices.

Selection Notes

Select this component when a low-power ARM9 solution with integrated PRU is required for mixed-signal applications. Consider the 375 MHz operating frequency and 1.2 V core voltage for power-sensitive designs. Evaluate peripheral multiplexing constraints if multiple communication interfaces are needed simultaneously.

Part Context

This part belongs to the AM1808 family of ARM-based microprocessors designed for embedded applications. It combines processing power with rich peripheral sets to support complex user interfaces and connectivity options in a single chip solution.

Replacement Considerations

Check for compatible parts within the same AM1808 family that may offer different clock speeds or package options. Verify pin compatibility and software register-level compatibility before substituting.
