The MAX3110E/MAX3111E combine a full-featured uni-

versal asynchronous receiver/transmitter (UART) with

±15kV ESD-protected RS-232 transceivers and inte-

grated charge-pump capacitors into a single 28-pin

package for use in space-, cost-, and power-con-

strained applications. The MAX3110E/MAX3111E also

feature an SPI™/QSPI™/MICROWIRE™-compatible

serial interface to save additional board space and

microcontroller (µC) I/O pins.

A proprietary low-dropout output stage enables the

2-driver/2-receiver interface to deliver true RS-232 per-

formance down to V

while consuming only 600µA. The receivers remain

active in a hardware/software-invoked shutdown, allow-

ing external devices to be monitored while consuming

only 10µA. Each device is guaranteed to operate at up

to 230kbps while maintaining true EIA/TIA-232 output

voltage levels.

The MAX3110E/MAX3111E’s UART includes a crystal

oscillator and baud-rate generator with software-pro-

grammable divider ratios for all common baud rates

from 300baud to 230kbaud. The UART features an 8-

word-deep receive FIFO that minimizes processor over-

head and provides a flexible interrupt with four

maskable sources. Two control lines (one input and

one output) are included for hardware handshaking.

The UART and RS-232 functions can be used together

or independently since the two functions share only

supply and ground connections (the MAX3110E/

MAX3111E are hardware- and software-compatible

with the MAX3100 and MAX3222E).
