STMicroelectronics today introduced the new Xpander Logic family to help customers overcome the limited number of Input/Output (I/O) ports in microcontroller and microprocessor-based embedded systems. Any existing or additional I/O-intensive tasks on the central processing unit can be now reassigned to the Xpander Logic IC that operates off ultra-low power and comes in a very small package, making it ideal for portable multimedia devices such as mobile phones, smartphones and personal digital assistants. The Xpander Logic family allows the existing system processor to use a wide range of intelligent functions through a standard and high-speed Inter-Integrated Circuit serial peripheral interface.
In production now, the devices are housed in very small packages (QFN16, microTFBGA25 and microTFBGA36).
