AM1808EZWTD4

Overview

The AM1808EZWTD4 is a low-power microprocessor based on the ARM926EJ-S core, operating at frequencies up to 456 MHz with a 1.3V supply voltage. It features a 361-ball NFBGA package and includes an integrated DDR2/mDDR controller, EMIFA, and PRUSS subsystem. The device supports 1.8V or 3.3V I/O levels and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrated Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores for deterministic control tasks
• Dual external memory interfaces supporting asynchronous memories via EMIFA and high-speed DDR2/mDDR controllers
• Comprehensive multimedia connectivity including USB 2.0 OTG, Ethernet MAC, and video port interface

Applications

• Industrial automation and control systems requiring real-time processing
• Automotive electronics applications such as instrument clusters
• Human-machine interface (HMI) devices with rich graphical displays

Procurement Notes

Verify that the specific suffix 'ZWT' corresponds to the 16 mm x 16 mm, 361-ball, 0.80 mm pitch PBGA package configuration. Confirm the operational frequency rating matches the 456 MHz specification associated with the 1.3V core voltage requirement before finalizing procurement orders.

Selection Notes

Select this component when deterministic real-time performance is required alongside general-purpose processing. Ensure the design accommodates the necessary external memory interfaces and utilizes the available GPIO multiplexing capabilities for the target application's peripheral requirements.

Part Context

This part belongs to the Texas Instruments Sitara AM1808 family of ARM-based microprocessors. It is designed for applications needing robust OS support and high processing performance in a compact form factor, serving as a bridge between simple microcontrollers and complex application processors.
