AM1707CZKB3

Overview

The AM1707CZKB3 is a Texas Instruments ARM microprocessor featuring an ARM926EJ-S core operating at 375 MHz (1.2V) or 456 MHz (1.3V). It integrates 168KB RAM, 64KB ROM, and 128KB additional SRAM with 16KB instruction and data caches. The device includes two PRU cores, USB 2.0 OTG, USB 1.1 OHCI, 10/100 Ethernet MAC, and multiple serial interfaces. It utilizes a 256-ball PBGA package.

Feature Summary

• Dual Programmable Real-Time Unit (PRU) cores for deterministic control tasks
• Integrated USB 2.0 OTG and USB 1.1 OHCI controllers with on-chip PHYs
• 10/100 Mbps Ethernet MAC with RMII interface and MDIO module
• Support for NOR, NAND, and SDRAM external memory via dedicated interfaces

Applications

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

Procurement Notes

Verify the specific suffix 'CZKB3' against official documentation to confirm temperature range and package details. Ensure compatibility with required power supply voltages of 1.2V or 1.3V for the CPU core and 3.3V for I/Os. Confirm that the 256-ball PBGA footprint matches your PCB design constraints.

Selection Notes

Select this component for applications requiring mixed processing capabilities with real-time determinism provided by the PRU subsystem. Consider the integrated memory and peripheral set if space is limited. Evaluate thermal performance requirements given the BGA package and operating frequencies up to 456 MHz.

Part Context

The AM1707 belongs to the Sitara family of ARM-based microprocessors from Texas Instruments. It is designed for OEMs and ODMs seeking robust OS support and rich user interfaces. The processor combines high-performance computing with low-power operation and extensive connectivity options.

Replacement Considerations

Consult official substitution guides for compatible parts within the Sitara family. Verify pinout and register compatibility before replacing existing designs.
