Overview
The AM1806EZWTD4 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 (16 mm x 16 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 USB 2.0 OTG, two I2C buses, two SPIs, three UARTs, two McBSPs, one McASP, LCD controller, VPIF, uPP, and PRUSS.
Feature Summary
- Integrated Programmable Real-Time Unit Subsystem (PRUSS) with dual independent cores for deterministic control tasks
- High-performance Enhanced Direct Memory Access Controller (EDMA3) supporting 64 channels and 16 quick DMA channels
- Flexible video and audio processing capabilities via Video Port Interface (VPIF) and Multichannel Audio Serial Port (McASP)
- Comprehensive connectivity suite including USB 2.0 OTG, MMC/SD interfaces, and multiple serial communication ports
Applications
- Set Top Box
- Industrial Automation
- Building Automation
- Medical and Healthcare Devices
- ePOS Systems
Procurement Notes
Verify the specific suffix 'ZWT' confirms the 361-ball NFBGA package with 0.80 mm ball pitch. Ensure the silicon revision matches project requirements, as revisions may affect peripheral availability or electrical characteristics. Confirm RoHS compliance status through official documentation before integration.
Selection Notes
Select this component when high-speed multimedia processing and deterministic real-time control are required in a single chip. The 456 MHz ARM926EJ-S core supports complex operating systems like Linux. Consider the extensive peripheral set for reducing external component count in designs requiring video capture, audio streaming, and industrial communication protocols.
Part Context
This part belongs to the Texas Instruments Sitara AM1806 family of low-power applications processors. It is designed for OEMs and ODMs seeking robust OS support and rich user interfaces. The family integrates mixed processor solutions combining general-purpose computing with specialized real-time capabilities.
Replacement Considerations
AM1806ZCE4: Same processor core but utilizes a 361-ball PBGA package with 0.65 mm pitch instead of the ZWT's 0.80 mm pitch. Verify footprint compatibility.
