S1R72V17B00A200

Controllers Overview

The S1R72V17 is a USB 2.0 host/device controller LSI designed for CPU interfacing. It supports standard bus widths including 8-bit and 16-bit configurations, accommodating both strobe and byte-enable (BE) modes. The device operates with an IOVDD/CVDD supply voltage ranging from 1.65 V to 3.6 V. It provides configurable endian settings for big-endian and little-endian CPUs via the CPU_Config register. The controller includes FIFO registers for data buffering and supports external clock inputs of 12 MHz or 24 MHz.

Controllers Feature Summary

• Supports flexible CPU interface connections with 8-bit and 16-bit bus width options.
• Configurable for both big-endian and little-endian data access modes.
• Includes internal FIFO registers for efficient data transmission handling.

Controllers Applications

• Integration with standard microcontrollers requiring USB connectivity.
• Connection to Freescale iMX21 processors for embedded systems.
• Development of USB host or device peripheral circuits.

Controllers Procurement Notes

Verify the specific ordering suffix against official Epson documentation to confirm package type and temperature range. Ensure the design utilizes the correct CPU_Config register settings for the target bus mode and endian configuration. Cross-reference the AC specifications with the connected CPU's bus cycle timing to guarantee signal integrity and compliance with the technical manual requirements.

Controllers Selection Notes

Select this component when a dedicated USB 2.0 controller interface is required for custom CPU designs. Evaluate the available bus width (8-bit vs 16-bit) and endian requirements of the host processor. Confirm that the system power supply falls within the 1.65 V to 3.6 V operating range. Review the CPUIF verification procedure in the connection guide to ensure proper initialization and clock setup during development.

Controllers Part Context

The S1R72V17 belongs to Epson's USB Interface IC family, functioning as a high-speed host and device controller. It is distinct from other series like the S2R72V18 by its specific focus on CPU interface guidelines and register-level control. This LSI serves as a bridge between USB protocols and general-purpose processing units, facilitating data exchange in embedded applications.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Epson directly for current equivalent models or updated series replacements if the S1R72V17 is no longer suitable for the application.
