SPI/MICROWIRE-Compatible UART and ±15kV ESD-

Protected RS-232 Transceivers with Internal Capacitors

0/MAX31E

General Description

Features

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.

♦ Integrated RS-232 Transceiver and UART in a

Single 28-Pin Package

♦ SPI/QSPI/MICROWIRE-Compatible µC Interface

♦ Internal Charge-Pump Capacitors—

No External Components Required!

♦ True RS-232 Operation Down to V

= +3V

(MAX3111E)

♦ ESD Protection for RS-232 I/O Pins

A proprietary low-dropout output stage enables the

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

±15kV—Human Body Model

±8kV—IEC 1000-4-2, Contact Discharge

±15kV—IEC 1000-4-2, Air-Gap Discharge

formance down to V

= +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.

♦ Single-Supply Operation

+5V (MAX3110E)

+3.3V (MAX3111E)

♦ Low Power

600µA Supply Current

10µA Shutdown Supply Current with

Receiver Interrupt Active

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.

♦ Guaranteed 230kbps Data Rate

♦ Hardware/Software-Compatible with MAX3100

and MAX3222E

Ordering Information

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).
