Dual Serial UART with 128-Word FIFOs
MAX3109
19-5806; Rev 2; 10/12
General Description
The MAX3109 advanced dual universal asynchronous
receiver-transmitter (UART) has 128 words of receive
and transmit first-in/first-out (FIFO) and a high-speed SPI
or I2C controller interface. The 2x and 4x rate modes
allow a maximum of 24Mbps data rates. A phase-locked
loop (PLL) and the fractional baud-rate generators allow
a high degree of flexibility in baud-rate programming and
reference clock selection.
Independent logic-level translation on the transceiver
and controller interfaces allows ease of interfacing to
microcontrollers, FPGAs, and transceivers that are pow-
ered by differing supply voltages. Automatic hardware
and software flow control with selectable FIFO interrupt
triggering offloads low-level activity from the host control-
ler. Automatic half-duplex transceiver control with pro-
grammable setup and hold times allow the MAX3109 to
be used in high-speed applications such as PROFIBUS-
DP. The 128-word FIFOs have advanced FIFO control,
reducing host processor data flow management.
The MAX3109 is available in a 32-pin TQFN (5mm x
5mm) package and is specified over the -40°C to +85°C
extended temperature range.
