Product Summary

The MAX3100CPD is an universal asynchronous receiver transmitter (UART). It is the first UART specifically optimized for small microcontroller-based systems. Using an SPI/MICROWIRE interface for communication with the host microcontroller (μC), the MAX3100CPD 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. IR-link communication is easy with the MAX3100CPD’s infrared data association (IrDA) timing mode. The applications of the MAX3100CPD 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 and Low-Cost IR Data Links for Computers/Peripherals.
