MAX3100EEE+

Controllers Overview

The MAX3100EEE+ is a universal asynchronous receiver/transmitter (UART) optimized for small microcontroller-based systems, featuring an SPI/MICROWIRE-compatible interface. It operates within a supply voltage range of +2.7V to +5.5V and supports data rates up to 230k baud using a 3.6864MHz crystal. The device includes an 8-word FIFO buffer, software-programmable baud-rate generator, and interrupt logic with four maskable sources. It functions in extended temperature ranges from -40°C to +85°C and is housed in a compact 16-pin QSOP package.
