QuickLogic (NASDAQ:QUIK) introduced a new UART (universal asynchronous receiver/transmitter) proven system block for use with its innovative Customer Specific Standard Product (CSSP) platforms. The high-performance core supports the full 3 Mbit/sec required for Bluetooth 2.1 and Enhanced Data Rate (EDR) operation.
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.
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 3 Mbits/sec. 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 QuickLogic’s CSSP proven system block library.
