AM1707CZKB4

Overview

The AM1707CZKB4 is a Texas Instruments ARM microprocessor based on the ARM926EJ-S core. It operates at clock frequencies of 375 MHz or 456 MHz, with the higher speed requiring a 1.3 V core voltage. The device integrates 16 KB instruction cache, 16 KB data cache, 8 KB vector table RAM, and 64 KB ROM. Peripheral features include an Ethernet MAC, USB 2.0 OTG, USB 1.1 OHCI, PRU subsystem, and multiple serial interfaces.

Feature Summary

• Integrates a Programmable Real-Time Unit (PRU) subsystem for deterministic control tasks
• Includes a 10/100 Mbps Ethernet MAC with RMII interface and MDIO module
• Features dual USB controllers supporting both High-Speed OTG and Full-Speed Host modes
• Provides multimedia capabilities via dedicated LCD controller and multichannel audio ports

Applications

• Industrial Automation
• Test and Measurement
• Home Automation
• Portable Data Terminals

Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm temperature range and silicon revision. Ensure the required operating frequency matches the specified core voltage requirements. Confirm package dimensions and pinout compatibility with existing PCB layouts before finalizing procurement orders.

Selection Notes

Select this component when a low-power ARM9 solution with integrated real-time processing is required. Consider the 456 MHz variant if maximum throughput is needed, noting the associated power implications. Evaluate the PRUSS capability for offloading time-critical tasks from the main CPU to optimize system performance.

Part Context

This part belongs to the AM170x Sitara ARM processor family designed for embedded applications. It combines high-performance computing with rich connectivity options in a single chip. The architecture supports robust operating systems and complex user interfaces suitable for industrial and consumer electronics markets.

Replacement Considerations

Consult the manufacturer's compatibility matrix for direct replacements. Verify that any substitute maintains identical pinout and peripheral functionality to ensure board-level compatibility without redesign.
