It handles the framing, baud-rate generation, and line control so the host MCU only needs to read and write bytes over SPI. The 150 µA supply current makes it practical for always-on or battery-backed ports where you do not want to keep a full UART peripheral powered. Supply voltage spans 2.7 V to 5.5 V. Operating temperature range is 0°C to 70°C. Packaged in a 16-QSOP (3.90 mm width SSOP footprint), the MAX3100CEE+T is available in Tape & Reel or Cut Tape for prototyping. The ROHS3 compliance is confirmed. ## Lifecycle and sourcing The MAX3100CEE+T is listed as Active with no end-of-life notice.","metaTitle":"MAX3100CEE+T SPI-to-UART Controller, RS232/RS485, 16-QSOP","metaDescription":"MAX3100CEE+T SPI/UART controller supports RS232 and RS485.
