AM1806BZWT4

Overview

The AM1806BZWT4 is an 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, HPI, and PRUSS.

Feature Summary

• Integrated Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores for deterministic control tasks
• Supports DDR2 and Mobile DDR external memory controllers alongside asynchronous EMIFA for NOR/NAND flash
• Includes Universal Parallel Port (uPP) for high-speed parallel data transfer to FPGAs and converters
• Features Video Port Interface (VPIF) supporting BT.656 and raw video capture/display channels

Applications

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

Procurement Notes

Verify the specific suffix 'BZWT4' against the manufacturer's current ordering guide to confirm package dimensions and pin pitch. Ensure compatibility with required silicon revision levels for your application. Confirm RoHS compliance status via the official datasheet before procurement.

Selection Notes

Select this component when high-performance ARM9 processing is combined with real-time control requirements via PRUSS. Suitable for designs needing extensive multimedia interfaces like VPIF and uPP. Verify that the 0.80 mm pitch NFBGA package fits the PCB layout constraints and thermal management strategy.

Part Context

Part of the Texas Instruments Sitara AM1806 family, designed for low-power embedded applications. It bridges general-purpose computing with real-time control needs. The ZWT variant specifically denotes the larger 16x16mm NFBGA package compared to the smaller ZCE option.

Replacement Considerations

Check for AM1806 variants with different suffixes (e.g., ZCE) if package size differs. No direct cross-manufacturer replacements are documented in the source material.
