Overview
Description
The µPD720201 is a USB host controller LSI compatible with the USB 3.0 and xHCI (eXtensible Host Controller Interface) 1.0 specifications. The system bus is compatible with the PCIe Gen2 specification. The controller provides four USB ports with LS (Low-Speed) / FS (Full-Speed) / HS (High-Speed) / SS (SuperSpeed) support.
The µPD720201 comes in a 68-pin QFN package and has the following improvements over previous products.
- Reduced power consumption in low-power mode to 4.5mW, a reduction of 90% compared with Renesas Electronics' existing products
- Improvements to the data transfer processing circuit provide an increase in the effective data write speed of more than 40% from existing products
- Firmware download function eliminates the need for external serial flash ROM

What is common mode rejection (CMR) of an operational amplifier?
CMR indicates the ratio of the input voltage to the varied input offset voltage when the input offset voltage has changed due to a change in the input voltage. CMR=ΔVI/ΔVIO Normally the DC variation is the target. If the CMR value is large, it indicates that, when ...

What is the maximum output voltage (Vom) of an operational amplifier?
This expresses the limit value at which the output of the operational amplifier is saturated when the prescribed power supply voltage is applied. There are two values: one for the positive power supply side and one for the negative power supply side. In addition, either a load resistance value (2 ...

What is offset voltage?
In an operational amplifier, the output voltage should theoretically be 0 V when the voltage differential between the input pins is 0 V. However, in reality, VBE of the positive and negative input transistors in the input stage's differential amplifier circuits differs. As a result, the voltage differential between ...
