Description
The MAX3107 is an advanced universal asynchronous receiver-transmitter (UART) with 128 words each of receive and transmit first-in/first-out (FIFO) that can be controlled through I²C or high-speed SPI™. The 2x and 4x rate modes allow a maximum of 24Mbps data rates. A phase-locked loop (PLL), prescaler, and fractional baud-rate generator allow for high-resolution baud-rate programming and minimize the dependency of baud rate on reference clock frequency.
Autosleep and shutdown modes help reduce power consumption during periods of inactivity. A low 640µA (typ) supply current and tiny 24-pin TQFN (3.5mm x 3.5mm) package make the MAX3107 ideal for low-power portable devices.
Integrated logic-level translation on the controller and transceiver (RX/TX and active-low RTS/active-low CTS) interfaces enable use with a wide selection of RS-232/RS-485 transceivers.
Automatic hardware and software flow control with selectable FIFO interrupt triggering offloads low-level activity from the host controller. Automatic half-duplex transceiver control with programmable setup and hold times allow the MAX3107 to be used in high-speed applications, for example Profibus-DP.
The MAX3107 is ideal for use in portable devices, industrial applications, and automotive applications. The MAX3107 is available in a 24-pin SSOP package and a 24-pin TQFN package. It is specified over the -40°C to +85°C extended ambient temperature range.
