Product Summary

The MAX3100CPD is an universal asynchronous receiver transmitter (UART).The MAX3100CPD 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 infrared data association (IrDA) timing mode. Applications of the MAX3100CPD 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.
