AM1707CZKBD4

Overview

The AM1707CZKBD4 is an ARM microprocessor based on the ARM926EJ-S core, operating at frequencies up to 456 MHz. It features a 32-bit RISC architecture with 16KB instruction and data caches, 8KB RAM for the vector table, and 64KB ROM. The device integrates a Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores, each containing 4KB of instruction RAM and 512 bytes of data RAM. Peripheral interfaces include USB 2.0 OTG, USB 1.1 OHCI, a 10/100 Mbps Ethernet MAC, three McASPs, and multiple timers.

Feature Summary

• Integrates a high-performance ARM926EJ-S processor core with hardware memory management capabilities
• Includes a dedicated PRUSS subsystem featuring two programmable real-time unit cores for deterministic control tasks
• Provides comprehensive connectivity through integrated USB controllers and an Ethernet MAC
• Supports multimedia applications via multichannel audio serial ports and enhanced capture modules

Applications

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

Procurement Notes

Verify the specific suffix 'CZKBD4' against official documentation to confirm temperature range and package details. Ensure compatibility with required power supply voltages, specifically the 1.3V nominal requirement for maximum frequency operation. Confirm that the 256-ball PBGA package dimensions align with the target PCB layout constraints.

Selection Notes

Select this component when a mixed-processor solution requiring robust OS support and rich user interfaces is needed. The inclusion of the PRUSS allows for offloading time-critical tasks from the main CPU. Consider the available external memory interfaces if large storage capacity beyond on-chip resources is required.

Part Context

This device belongs to the Sitara AM170x family of ARM microprocessors designed for OEMs and ODMs. It combines processing performance with low power consumption and a fully integrated peripheral set. The architecture supports both 32-bit and 16-bit instructions to balance performance and code density.

Replacement Considerations

Consult the manufacturer's product migration guide for verified substitutes within the Sitara family. Verify pinout and register compatibility before replacing existing designs.
