MAX3107: SPI/I²C UART with 128-word FIFO in a Tiny TQFN

Published:2011/8/31 21:45:00 Author:Phyllis From:SeekIC

The MAX3107 is designed as 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™. Its data rate can reach a maximum of 24Mbps thanks to its 2x and 4x rate modes. A phase-locked loop (PLL), prescaler, and fractional baud-rate generator minimize the dependency of baud rate on reference clock frequency and make sure the high-resolution baud-rate programming.




With autosleep and shutdown modes, the power consumption during inactive period is extraordinarily low. A low 640µA 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.
