Seiko Epson Corporation has developed the S1R72V18, the newest product in its S1R72V Series of USB controller LSI products that are compatible with high-speed USB 2.0.
Shipments of samples of the new model have already commenced.
The S1R72V Series products already in volume production making it possible for users to connect to computers and download high-volume files at super high speeds, and tap into USB memory to transmit music data at high speeds. In terms of standby power consumption, the S1R72V17 model consumes only 3.9 ?W of power during Sleep Mode. Due to their low power consumption and other features, the products have contributed to the development of equipment and mobile terminals for which noise reduction is an extremely important factor.
The newly developed S1R72V18 enables isochronous transfer which is used when connecting to portable music players. In addition, the new model comes equipped with two high-speed USB 2.0 ports: one shared port for both device and host functions and one port exclusively for host functions. The S1R72V18 is the first model in the series to be capable of operating two USB ports simultaneously. The main target application for this model is car navigation systems for which multiple ports are becoming increasingly common. Consequently, the S2R72V18, which is now under development, will feature a guaranteed operating temperature range of -40°C to 105°C, and is expected to meet the specifications for the AEC-100 industry standard for automobile electronics quality. |
