Maxim MAX3349EA USB 2.0 Full-Speed Transceiver Datasheet
The MAX3349EA provides a full‑speed USB 2.0 interface to low‑voltage microprocessors or ASICs and includes a special UART multiplexing mode that routes external UART signals to the D+ and D‑ pins. It supports enumeration, suspend, VBUS detection, and can operate in either USB mode or UART mode depending on the presence of VBUS.
The device is offered in 16‑pin TQFN and 16‑bump UCSP packages, operates over –40 °C to +85 °C, and features internal series termination resistors, a 1.5 kΩ pull‑up on D+, and separate UART voltage supply. Electrical and timing characteristics are detailed for both USB and UART operation.
