Atmel Announces USB to UART Bridge Controller
SAN JOSE, Calif.----Oct. 25, 2000--Atmel
Corporation (Nasdaq:ATML) today released a Universal Serial Bus (USB)
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 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) and the UART, without
intervention of the processor. Segmentation and Reassembly (SAR) 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.
