AM1808BZWT4

Overview

The AM1808BZWT4 is a Texas Instruments Sitara ARM926EJ-S microprocessor operating at 456 MHz with a 1.3 V core voltage. It features a 361-ball NFBGA package (16x16 mm, 0.80 mm pitch). The device includes 16 KB instruction cache, 16 KB data cache, 8 KB vector RAM, and 64 KB ROM. Peripheral interfaces include EMAC, SATA, USB 2.0 OTG, USB 1.1 OHCI, LCD controller, VPIF, uPP, and two PRU cores.

Feature Summary

• Dual Programmable Real-Time Unit (PRU) subsystem for deterministic control tasks
• Integrated SATA controller supporting high-speed mass storage connectivity
• Comprehensive multimedia interface set including LCD controller and video port interface
• Flexible external memory support via DDR2/mDDR controller and asynchronous interfaces

Applications

• Set Top Box
• Industrial Automation
• Medical and Healthcare Devices
• Building Automation Systems

Procurement Notes

Verify the specific suffix 'BZWT4' against the manufacturer's current ordering guide to confirm package dimensions and silicon revision. Ensure compatibility with required I/O voltages (1.8 V or 3.3 V) during design-in. Confirm moisture sensitivity level handling requirements prior to assembly.

Selection Notes

Select this component when deterministic real-time processing is required alongside general-purpose ARM9 execution. The integrated PRUSS allows offloading of time-critical tasks from the main CPU. Verify that the 361-ball NFBGA footprint matches the PCB layout constraints and thermal dissipation capabilities of the target enclosure.

Part Context

This part belongs to the Texas Instruments Sitara AM1808 family of low-power applications processors. It shares architectural similarities with other ARM9-based devices in the series but is distinguished by its specific clock speed, package type, and peripheral configuration optimized for embedded multimedia and industrial control applications.
