Product Summary

The MAX3100CEE+ is an universal asynchronous receiver transmitter (UART). The MAX3100CEE+ is the first UART specifically optimized for small microcontroller-based systems. Using an SPI/Microwire. interface for communication with the host microcontroller (μC), the MAX3100CEE+ comes in a compact 16-pin QSOP. The asynchronous I/O is suitable for use in RS-232, RS-485, IR, and opto-isolated data links. The applications of the MAX3100CEE+ include Handheld 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.
