IMP16C854 Quad Universal Asynchronous Receiver/Transmitter (UART) FIFO Counter & 128-BYTE FIFO
■The IMP16C854 is a universal asynchronous receiver and transmitter (UART) and is available in different packages. The IMP16C854 is an quad UART with enhanced features like 128 byte deep transmit and receive fifo’s, programmable transmit and receive trigger levels to enable data rates of 2Mbps with low system interface overhead and in band/out of band flow controls. Status registers provide the user with error indications and operational status, modem interface control status. Interrupt levels are software programmable to suit different system requirements. Internal loopback capability facilitates diagnostics. Low power modes of IMP16C854 enables its use in critical low power applications.
■The IMP16C854 is available in industry standard 64 pin TQFP, 68 pin PLCC and 100 pin QFP packages. Each additional pin on the package makes available additional range of features for the application.
●Key Features
