UPD720115K8-611-BAK-M1-A

Controllers Overview

The UPD720115K8-611-BAK-M1-A is a USB 2.0 hub controller compliant with the Universal Serial Bus Specification Revision 2.0. It supports Low Speed (1.5 Mbps), Full Speed (12 Mbps), and High Speed (480 Mbps) data rates. The device integrates two on-chip voltage regulators, eliminating the need for external components by generating 3.3V and 1.05V from a 5V VDD supply. It features configurable downstream port counts of 2, 3, or 4, with support for individual or group power control and overcurrent detection. The controller operates within a temperature range of -40°C to +85°C and utilizes a 40-pin QFN package measuring 6 mm x 6 mm.

Controllers Feature Summary

• Supports USB 2.0 Link Power Management for optimized energy efficiency.
• Configurable downstream port architecture allowing selection of 2, 3, or 4 ports.
• Integrated dual voltage regulators reduce system bill of materials.
• Capable of outputting a 24 MHz clock signal to non-removable devices connected to downstream ports.

Controllers Applications

• Charging hubs for smartphones and tablets supporting USB Battery Charging Specification 1.2.
• Industrial electronic systems requiring robust operation across extended temperature ranges.
• Consumer electronics utilizing USB 2.0 connectivity for peripheral expansion.

Controllers Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm pin compatibility and electrical characteristics. Ensure that the selected variant matches the required downstream port configuration and packaging dimensions. Cross-reference the part number with current datasheets to validate active status and availability constraints before finalizing procurement plans.

Controllers Selection Notes
