The MAX3100EE from Maxim Integrated is a sophisticated UART (Universal Asynchronous Receiver-Transmitter) device designed to expand the serial capabilities of any microcontroller with an SPI or MICROWIRE interface. This product is particularly useful in applications where an additional UART is needed, or in systems that lack a serial port altogether.

With its integrated 128-word FIFOs (First-In, First-Out memory queues) for both transmit and receive, the MAX3100EE is equipped to handle high-speed data without overburdening the host processor. This buffering capability ensures smooth data flow and improved system reliability, making it an ideal choice for complex and data-intensive tasks.

The device operates over a wide voltage range, from 3.0V to 5.5V, providing flexibility for various power supply requirements and making it suitable for both 3V and 5V systems. Its versatility is further enhanced by the inclusion of a programmable baud rate generator, which allows for fine-tuning of communication speeds to match specific application needs.

Key Features:

• SPI/MICROWIRE-Compatible Interface for Easy Integration
• 128-Word FIFOs for Both Transmit and Receive Functions
• Programmable Baud Rate Generator
• Wide Operating Voltage Range: 3.0V to 5.5V
• IrDA Timing Compliant to 115.2kbps
• Low Power Shutdown Mode
• External or Internal Clocking Options
• Available in a 20-Pin SSOP Package

For applications requiring infrared (IrDA) communication, the MAX3100EE is also compliant with IrDA timing up to 115.2kbps, offering an additional layer of connectivity. Furthermore, the device features a low power shutdown mode, which significantly reduces power consumption when the UART is not in active use, making it ideal for battery-powered and power-sensitive applications.

Its small form factor, the 20-pin SSOP (Shrink Small Outline Package) package, allows for space-efficient designs, which is particularly beneficial in compact and portable devices. Whether implemented in industrial control systems, networking equipment, or consumer electronics, the MAX3100EE provides a reliable and efficient solution for serial communication expansion.
