AM1806BZWTD4

Overview

The AM1806BZWTD4 is a Texas Instruments 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, two SPI, three UARTs, two McBSPs, one McASP, LCD controller, VPIF, uPP, and PRUSS.

Feature Summary

• Integrated Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores for deterministic control tasks.
• Supports DDR2 and Mobile DDR memory controllers alongside asynchronous EMIFA for flexible external memory configurations.
• Includes dedicated video processing interfaces such as VPIF and LCD controller for multimedia applications.
• Features enhanced high-resolution pulse-width modulators (eHRPWM) and capture modules for motor control.

Applications

• Set Top Box
• Industrial Automation
• Building Automation

Procurement Notes

Verify the specific suffix 'ZWT' confirms the 16x16mm NFBGA package with 0.80mm ball pitch. Ensure the silicon revision matches project requirements. Confirm RoHS compliance status through official documentation. Check for moisture sensitivity level handling instructions prior to assembly.

Selection Notes

Select this component when a 456 MHz ARM9 processor with integrated PRU capabilities is required. Suitable for designs needing robust video interfaces and multiple serial communication ports. Consider power consumption differences between 375 MHz and 456 MHz variants based on thermal constraints.

Part Context

Part of the Sitara AM1806 family, designed for low-power embedded applications. Combines general-purpose processing with real-time control capabilities. Targets markets requiring rich user interfaces and connectivity in compact form factors.

Replacement Considerations

Check AM1806EZCE4 for ZCE package variant. Verify AM1808 series for potential pin-compatible upgrades if higher performance is needed.
