Product Summary

The MAX3100EEE+ is an universal asynchronous receiver transmitter (UART). It is the first UART specifically optimized for small microcontroller-based systems. The MAX3100EEE+ includes a crystal oscillator and a baudrate generator with software-programmable divider ratios for all common baud rates from 300 baud to 230k baud. A software- or hardware-invoked shutdown lowers quiescent current to 10μA, while allowing the MAX3100EEE+ to detect receiver activity. An 8-word-deep first-in/first-out (FIFO) buffer minimizes processor overhead. The applications of it are Hand-Held Instruments, Intelligent Instrumentation, UART in SPI Systems, Small Networks in HVAC or Building Control, Isolated RS-232/RS-485: Directly Drives Opto-Couplers, Low-Cost IR Data Links for Computers/Peripherals
