Product details

What this SPI/UART controller brings to a serial port

The MAX3100EEE+T from Maxim Integrated is a SPI/UART controller that handles both RS232 and RS485 protocols from a single chip. It talks to a host microcontroller over SPI and presents a full UART on the other side — no extra level translators needed if your system runs on a 2.7V to 5.5V rail. The 150 µA supply current means you can leave it powered on a battery-backed serial port without draining the pack overnight.

Industrial temperature range and package fit

Rated from -40°C to 85°C, this part is at home in factory-floor RS485 links, outdoor telecom gear, and any enclosure that sees seasonal swings. The 16-SSOP package (3.90 mm body width) fits a tight PCB layout — about the same footprint as a small SOIC, but narrower. The supplier device package is listed as 16-QSOP, which is the same mechanical outline; the naming difference is a Maxim catalog thing, not a footprint change.

Lifecycle and sourcing — active, no LTB clock ticking

Maxim lists the MAX3100EEE+T as Active with ROHS3 compliance. No last-time-buy notice, no NRND flag — you can qualify it into a production BOM without worrying about an imminent EOL.

Frequently asked questions

Can MAX3100EEE+T be used with RS232 and RS485 protocols simultaneously?

The part supports both RS232 and RS485 protocols, but it is a single UART channel — you would need to switch the line transceivers externally if you want both protocols on the same connector. It cannot drive both protocol types at the same time on separate pins without external muxing.

What is the closest pin-compatible alternative to MAX3100EEE+T?

The base MAX3100 (non-EEE+T suffix) is the same die in a different package or tape option — the electrical specs are identical. For a different protocol set, look at the MAX3111 series which adds an integrated RS232 transceiver, but the pinout differs.
