AM1806BZWT3

Overview

The AM1806BZWT3 is a Texas Instruments ARM926EJ-S microprocessor operating at 456 MHz with a 1.3 V core voltage. It features a 361-ball PBGA 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, HPI, and PRUSS.

Feature Summary

• Integrated Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores for deterministic control tasks
• Enhanced Direct Memory Access Controller (EDMA3) providing 64 independent DMA channels across two controllers
• Support for DDR2 and Mobile DDR external memory with up to 256-MB address space per interface
• Universal Parallel Port (uPP) enabling high-speed parallel data transfer to FPGAs and converters

Applications

• Set Top Box
• Industrial Automation
• Building Automation
• Medical, Healthcare, Fitness
• ePOS

Procurement Notes

Verify the specific suffix BZWT3 against the manufacturer's official ordering guide to confirm the package dimensions and ball pitch. Ensure the silicon revision matches the target application requirements. Confirm RoHS compliance status through the current datasheet documentation before procurement.

Selection Notes

Select this component when a 456 MHz ARM926EJ-S processor is required with integrated PRU capabilities. Verify that the 0.80 mm pitch PBGA package fits the PCB layout constraints. Check peripheral multiplexing availability if multiple interfaces are needed simultaneously.

Part Context

This part belongs to the Texas Instruments Sitara AM1806 series of ARM-based microprocessors. It is designed for applications requiring robust OS support and rich user interfaces. The series integrates mixed processing capabilities combining an ARM core with programmable real-time units.
