AM1808BZCEA3

Overview

The AM1808BZCEA3 is a Texas Instruments Sitara ARM926EJ-S microprocessor operating at 375 MHz with a 1.2 V core voltage. It features a 361-ball NFBGA package (13x13 mm, 0.65 mm pitch). The device includes 16 KB instruction cache, 16 KB data cache, 8 KB vector RAM, and 64 KB ROM. I/O supports 1.8 V or 3.3 V LVCMOS standards.

Feature Summary

• Integrated Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores for deterministic control tasks
• Comprehensive connectivity including 10/100 Mbps Ethernet MAC, USB 2.0 OTG, and SATA controller
• Rich peripheral set featuring LCD controller, video port interface, and multiple serial communication interfaces
• Hardware memory protection units to partition system tasks between the ARM processor and other masters

Applications

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

Procurement Notes

Verify the specific suffix 'A3' against the manufacturer's official documentation to confirm silicon revision level and production status. Ensure the NFBGA-361 package dimensions match the target PCB footprint. Confirm that the 1.2 V core voltage requirement aligns with the system power design.

Selection Notes

Select this component when deterministic real-time performance is required alongside general-purpose processing via the PRUSS. The 375 MHz speed grade is suitable for applications requiring robust OS support and rich user interfaces without the higher power consumption of advanced Cortex-A series processors.

Part Context

This part belongs to the Texas Instruments Sitara AM1808 family, designed as a low-power applications processor. It targets OEMs and ODMs needing flexible mixed-processor solutions with high code density and efficient Java execution capabilities through the ARMv5TEJ instruction set.

Replacement Considerations

AM1808EZCEA3: Identical specifications but operates at 456 MHz with a 1.3 V core voltage.
