S1R72V17F00C200

Controllers Overview

The S1R72V17F00C200 is a USB 2.0 host/device controller LSI manufactured by Epson ICs, designed for integration with external CPUs via a dedicated CPU interface. It supports High-Speed (480 Mb/s), Full-Speed (12 Mb/s), and Low-Speed (1.5 Mb/s) data transfers compliant with the USB 2.0 standard. The device accommodates flexible bus configurations, including 16-bit strobe mode, 16-bit byte-enable mode, and 8-bit modes. It operates within an IOVDD/CVDD supply voltage range of 1.65 V to 3.6 V.

Controllers Feature Summary

• Supports USB 2.0 High-Speed, Full-Speed, and Low-Speed transfer protocols
• Configurable CPU interface supporting 16-bit strobe, 16-bit BE, and 8-bit bus modes
• Includes internal PLL oscillator and programmable wake-up timer
• Provides specific verification procedures for CPU-IF connection integrity

Controllers Applications

• Integration with standard CPUs using 16-bit or 8-bit parallel interfaces
• Connection to Freescale iMX21 processors utilizing 16-bit BE mode
• Embedded systems requiring USB host or device functionality

Controllers Procurement Notes

Verify the exact ordering suffix against the manufacturer's current catalog to confirm package type and tape/reel specifications. Confirm that the component meets all required electrical standards for the target application environment. Ensure compatibility with the intended CPU interface timing requirements before finalizing procurement.

Controllers Selection Notes

Select this controller when a dedicated USB 2.0 solution with flexible CPU interfacing is required. Evaluate the target processor's bus width capabilities to determine if 8-bit or 16-bit mode is optimal. Consider the power supply constraints, as the device requires a 1.65 V to 3.6 V IOVDD/CVDD range. Review the AC specification timings to ensure the host CPU can meet the setup and hold time requirements.

Controllers Part Context

This component belongs to the S1R72V17 series of USB controllers from Epson ICs. The series provides hardware-level USB protocol handling, offloading processing tasks from the main system CPU. It is distinct from general-purpose microcontrollers, serving specifically as an interface bridge between the USB bus and the host processor.

Controllers Replacement Considerations

Consult the official Epson replacement guide for direct substitutes. Verify pinout compatibility and register mapping if considering alternative USB controllers from other manufacturers.
