µPD720114
ECOUSB™ Series
4 port USB 2.0 Hub controller
µPD720114 is a USB 2.0 complaint Hub Controller which is suited for "Ecological Solutions". Controller in such a small package integrates the 2.5 V internal voltage regulator for core logic, termination resistances, and reduces the number of external components needed. It enables shrinking the BOM (Bill of Materials) for the board design. Also, controller's power consumption is greatly reduced when the Hub is active or standby mode through "power saving technology" implementation. The Hub Controller has 4 down stream-facing port (maximum) and LED port status indicators. It is suited for the USB Boxed Hub, Monitors, Port replicator, and many applications for PC.
Features
- USB 2.0 Certified by USB Implements Forum (Test ID = 30000001, 30000004)
- USB 2.0 specification compliant
- 4 down stream port (max)
- Integrated "Transaction Translator" supports "split transaction".
