MAX3100EEE+

The MAX3100EEE+ is a SPI/MICROWIRE-compatible Universal Asynchronous Receiver Transmitter (UART) for small microcontroller-based systems. Using an SPI™/MICROWIRE™ interface for communication with the host microcontroller (μC), the MAX3100 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 MAX3100's infrared data association (IrDA) timing mode. The MAX3100 includes a crystal oscillator and a baud rate generator with software-programmable divider ratios for all common baud rates from 300baud to 230kbaud. A software- or hardware-invoked shutdown lowers quiescent current to 10μA, while allowing the MAX3100 to detect receiver activity. An 8-word-deep first-in/first-out (FIFO) buffer minimizes processor overhead. This device also includes a flexible interrupt with four maskable sources, including address recognition on 9-bit networks.

• Up to 230kbaud with a 3.6864MHz crystal
• 9-bit Address-recognition interrupt
• Receive activity interrupt in shutdown
• Schmitt-trigger inputs for opto-couplers
