QuickLogic Corp. has launched a new UART proven system block for use with its innovative customer specific standard product (CSSP) platforms. The high-performance core supports the full 3Mbps required for Bluetooth 2.1 and Enhanced Data Rate (EDR) operation.

The UART has been used as a general-purpose serial communications function for decades, but are typically designed for low data-rate applications such as a PC serial port. More recently, UARTs have become the most common form of host controller interface for Bluetooth communications. With the advent of Bluetooth 2.0/2.1 and its EDR transfer mode for high-speed streaming, UARTs traditionally used in mobile application processors are proving to be too slow. The new UART system block from QuickLogic offers the level of performance that Bluetooth 2.1 + EDR requires.

QuickLogics high-speed UART solution allows portable device OEMs and ODMs to quickly implement Bluetooth 2.1 capability without waiting for application processor vendors to upgrade their embedded UARTs to the required performance, says Howard Li, QuickLogics senior platform solution marketing manager. Together with the flexibility of QuickLogics CSSP platform approach, this solution allows designers to gain a competitive advantage and create product differentiation.

The high-speed UART solution is a proven system block that occupies five customizable building blocks (CBBs) within the programmable fabric in either PolarPro or ArcticLink CSSP families of solution platforms. It offers configurable flow control and FIFO access as well as a baud rate customizable for different application requirements, with speeds up to 3Mbps.

Applications for the UART system block include Bluetooth EDR voice communications between mobile handsets and hands-free headsets, wireless communications between game controllers and game consoles, and the streaming of multimedia files between devices, as well as traditional serial links to keyboards, mice, portable storage and the like. Software support for the high-speed UART system block includes drivers for Windows CE, Windows Mobile and Linux.

The high-speed UART solution is available immediately as part of QuickLogics CSSP proven system block library.
