General Description
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
CC
= +3V (+4.5V for MAX3110E)
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).
