MAX3100EEE+T

The MAX3100EEE+T is a SPI/MICROWIRE compatible UART in 16 pin QSOP package. This is the first UART specifically optimized for small microcontroller based systems. By using an SPI/MICROWIRE interface for communication with host microcontroller (µC), the asynchronous I/O is suitable for use in RS232, RS485, IR and opto-isolated data links. IR-link communication is easy with device's infrared data association (IrDA) timing mode. It includes a crystal oscillator and a baudrate generator with software programmable divider ratios for all common baud rates from 300 baud to 230k baud and two hardware handshaking control lines are included (one input and one output). A software or hardware invoked shutdown lowers quiescent current to 10µA while allowing the IC to detect receiver activity. This device is used in intelligent instrumentation, UART in SPI systems, small networks in HVAC or building control and low cost IR data links for computers/peripherals.
