Atmel Announces USB to UART Bridge Controller.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 25, 2000 Atmel Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) today released a Universal Serial Bus See USB. (hardware, standard) Universal Serial Bus - (USB) An external peripheral interface standard for communication between a computer and external peripherals over an inexpensive cable using biserial transmission. (USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. ) to Universal Asynchonous Receiver Transmiter (UART) Bridge controller (AT76C711) based on its 8-bit AVR(TM) microcontroller. The AT76C711 can be used in applications where peripherals supporting fast serial asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. or synchronous transfer of data have to communicate with a host or other peripherals through a high-speed serial link like USB. The AT76C711, running up to 24 MHz, is designed to provide high-speed USB interface to devices that need to communicate with a base station through fast serial links like UARTs and IrDA interfaces. The AT76C711 has two UARTs, one that can be used as an IrDA interface and an integrated USB interface with a devoted DMA controller. The DMA controller is able, under firmware control, to transfer data between the Dual Port Random Access Memory (DPRAM DPRAM Dual Port Random Access Memory DPRAM Dual Port Ram ) and the UART, without intervention of the processor. Segmentation and Reassembly segmentation and reassembly - segmentation (SAR (Segmentation And Reassembly) The protocol that converts data to cells for transmission over an ATM network. It is the lower part of the ATM Adaption Layer (AAL), which is responsible for the entire operation. See AAL. SAR - segmentation and reassembly ) of the transmitted and received packets through the UART are also executed with the aid of the DMA controller under firmware control. Other features, besides a high-speed 8-bit microcontroller and 3K Bytes of DPRAM that make the AT76C711 attractive is the 2K Bytes of SRAM for data storage, 8K x 16-bit in-system SRAM for program code and on-chip boot strap ROM for program uploading. "With computers slowly phasing out the RS-232 interface, many customers will need a vehicle that allows them to bridge these gap stated," Richard Bisset, Product Marketing Director for Atmel Multimedia & Communications. "Our AT76C711 is a part that can benefit various applications, USB to UART bridge, USB to IrDA bridge and two UARTs multiplexed into a high speed USB uplink to name just a few. To allow customers to evaluate this part, we have an Evaluation Kit (AT76C711-EK) that is also offered as a reference design." The AT76C711 comes in a 64-pin TQFP package and is currently in production. In high volume, the AT76C711 is priced at $4.85. The Evaluation Kit, AT76C711-EK is priced at $149.00.
