Its 128-byte FIFO buffers incoming and outgoing data, reducing the interrupt service rate on the host MCU and smoothing throughput on half-duplex RS485 networks. The device operates from a 2.35 V to 3.6 V supply, drawing 650 µA typical, and is specified over the -40°C to 85°C industrial temperature range — a fit for embedded control, telecom line cards, and industrial sensor interfaces where the host lacks a dedicated UART or needs protocol translation. ## Supply rail and interface compatibility The 2.35 V to 3.6 V supply range covers 3.3 V and 1.8 V logic rails but not 5 V — the host I²C or SPI lines must be 3.3 V tolerant. The UART side connects directly to RS232 level shifters or RS485 transceivers; the 128-byte FIFO lets you run higher baud rates without dropping characters, especially useful when the host bus is shared or slow. The 650 µA supply current is low enough for battery-backed or power-sensitive designs, though the transceiver itself will dominate the link budget. ## Package and footprint Housed in a 24-pin SSOP (0.209\" body width, 5.30 mm), the MAX3107EAG+ uses a fine-pitch (0.65 mm) footprint common to many Maxim UARTs and GPIO expanders. The supplier device package is 24-SSOP. The listed shipping medium is tube; reel or tape options may be available under alternate order codes. No special thermal management is needed at 650 µA. ## Lifecycle and compliance It is ROHS3 compliant.","metaTitle":"MAX3107EAG+ UART Controller, SPI/I²C, 128 FIFO, 24-SSOP","metaDescription":"MAX3107EAG+ UART controller with SPI/I²C interface, 128-byte FIFO, 650 µA supply, 2.35V–3.6V, -40°C to 85°C.
