S1R72C05F15E100

Controllers Overview

The S1R72C05F15E100 is a USB host and device controller LSI supporting USB 2.0 high-speed mode with separate host and device ports. It features an IDE interface for HDD integration, supporting ATA/ATAPI6 PIO modes 0-4, Multi-word DMA, and UDMA modes 0-5. The chip includes built-in FS/HS termination, a 4.5 kB shared USB FIFO, and a 64 B Media FIFO. Power management offers six states from SLEEP to ACT_ALL. It supports 16-bit CPU interfaces with DMA channels and operates within a -40°C to 85°C temperature range.

Controllers Feature Summary

• Supports USB 2.0 High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) transfers with dedicated channel architecture.
• Integrates IDE Host function compliant with ATA/ATAPI6 standards for direct HDD connectivity.
• Includes internal termination resistors for both USB Device and Host ports, eliminating external impedance adjustment components.
• Features comprehensive power management with six distinct operational states to optimize energy consumption.

Controllers Applications

• Mobile electronic devices requiring integrated storage solutions
• Car-mounted electronic systems with built-in hard disk drives
• USB peripherals utilizing combined host and device capabilities

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Confirm availability status as this component series may be subject to discontinuation or limited production runs. Ensure compatibility with existing system power sequencing requirements before procurement.

Controllers Selection Notes

Select this component when a single LSI must manage both USB host and device functions alongside IDE storage control. Verify that the target application requires the specific 16-bit CPU interface width and DMA capabilities provided. Ensure the design accommodates the required three-voltage power supply system (3.3V, 1.8V, and variable CVDD).

Controllers FAQ

Does the S1R72C05F15E100 require external termination resistors for USB connections?

No, the LSI includes built-in FS/HS termination resistors for both the device and host ports, eliminating the need for external impedance adjustment circuits.

What IDE transfer modes are supported by this controller?

The controller supports ATA/ATAPI6 standards, including PIO modes 0 to 4, Multi-word DMA, and Ultra DMA modes 0 to 5.

How is the boundary scan function configured if not used?

If boundary scan is not utilized, the TEST, TCK, TMS, TDI, and TRST terminals should all be set to Low, and the TDO terminal should be left open.
