TI announces family of Universal Serial Bus interface chips
Texas Instruments disclosed the development of the industry 's most comprehensive family of Universal Serial Bus (USB) interface chips. Samples of a seven-port USB hub device, the TUSB2070, and a four-port hub device, the TUSB2040, are available now. Other initial devices in the product family include a Hub with I2C Interface to enable USB Monitor Control and a Peripheral Interface Controller for use with popular microcontrollers and DSPs. Lastly, a Peripheral Interface Macrocell will soon be available such that USB functionality can be easily and rapidly included in Application Specific Integrated Circuit (ASIC) and customizable Digital Signal Processor (cDSP) designs. USB is an emerging industry standard designed for PC peripherals with low-to-medium data transfer requirements. Its 12 Mbps transmission capability provides both asychronous and isochronous (real-time) data transmission over a 4-wire cable. This more than meets the needs of most existing peripherals including keyboards, mice, modems, printers, and digital stereo audio. Additionally, USB supports hot plug-and-play so that adding a peripheral becomes as simple as plugging it into a USB connector. Suggested resale pricing of the TUSB2070 in quantities of 1,000 is $5.00. Suggested resale pricing of the TUSB2040 in quantities of 1,000 is $4.10. |
