Product Description

The MAX3109ETJ+ is a dual serial UART with 128word FIFOs in 32 pin TQFN package. This advanced dual universal asynchronous receiver-transmitter (UART) has 128words of receive and transmit first-in/first-out (FIFO) and high speed SPI or I2C controller interface. The 2x and 4x rate modes allow maximum of 24Mbps data rates. A phase locked loop (PLL) and fractional baud rate generators allow high degree of flexibility in baud rate programming and reference clock selection. The independent logic level translation on transceiver and controller interfaces allows ease of interfacing to microcontrollers, FPGAs and transceivers that are powered by differing supply voltages. Automatic hardware and software flow control with selectable FIFO interrupt triggering off loads low level activity from host controller. Automatic half duplex transceiver control with programmable set-up and hold times allow the MAX3109 to be used in high speed applications such as PROFIBUSDP.
Analogue Supply voltage range from 1.71V to 3.6V (internal PLL disabled and bypassed)
Operating temperature range from -40°C to 85°C
Register compatible with MAX3107, MAX3108 and MAX14830 devices
SPI up to 26MHz clock rate and fast mode plus I2C up to 1MHz
Automatic active-low RTS and active-low CTS flow control
Automatic XON/XOFF software flow control and line noise indication
Special character detection and 9bit multidrop mode data filtering
SIR and MIR compliant IrDASM encoder/decoder
500µA VCC supply current (1.8MHz crystal oscillator active, PLL disabled) and 1µA shutdown current
Two timers routed to GPIOs, 8 flexible GPIOs with 20mA drive capability
