AM1806BZCEA3

Overview

The AM1806BZCEA3 is an ARM926EJ-S microprocessor from the Sitara family, operating at 456 MHz with a 1.3V core voltage. It features a 32-bit RISC architecture with 16KB instruction and data caches, 8KB RAM, and 64KB ROM. The device includes two Programmable Real-Time Unit (PRU) cores, each with 4KB instruction RAM and 512 bytes of data RAM. Connectivity options include a USB 2.0 OTG port, three UARTs, two SPIs, two I2Cs, and two MMC/SD interfaces. Memory support covers EMIFA for NOR/NAND/SDRAM and a DDR2/mDDR controller. The component is housed in a 361-ball PBGA package.

Feature Summary

• Integrates dual Programmable Real-Time Unit (PRU) cores for deterministic real-time control tasks alongside the main ARM processor.
• Provides flexible video input/output capabilities through a dedicated Video Port Interface (VPIF) supporting BT.656 and raw formats.
• Includes a Universal Parallel Port (uPP) designed for high-speed data transfers to FPGAs and data converters.
• Features an Enhanced Direct Memory Access Controller (EDMA3) with 64 independent channels for efficient peripheral-to-memory data movement.

Applications

• Set Top Box
• Industrial Automation
• Building Automation

Procurement Notes

Verify the specific suffix 'A3' against official Texas Instruments documentation to confirm silicon revision or packaging details. Ensure compatibility with required operating temperatures and voltage levels before integration. Cross-reference the part number with current datasheets to validate availability and production status.

Selection Notes

Select this processor for applications requiring deterministic real-time performance via PRUs combined with rich multimedia interfaces. Consider the DDR2/mDDR memory controller requirements and the specific pin multiplexing constraints when designing the system architecture. Evaluate thermal management needs for the 456 MHz operation mode.
