SPI/MICROWIRE-Compatible UART and ±15kV ESD-
Protected RS-232 Transceivers with Internal Capacitors
Detailed Description
The MAX3110E/MAX3111E contain an SPI/QSPI/MICROWIRE-
compatible UART and an RS-232 transceiver with two
drivers and two receivers. The UART is compatible with
SPI and QSPI for CPOL = 0 and CPHA = 0. The UART
supports data rates up to 230kbaud for standard UART
bit streams as well as IrDA and includes an 8-word
receive FIFO. Also included is a 9-bit-address recogni-
tion interrupt.
The RS-232 transceiver has electrostatic discharge
(ESD) protection on the transmitter outputs and the
receiver inputs. The internal charge-pump capacitors
minimize the number of external components required.
The RS-232 transceivers meet EIA/TIA-232 specifica-
tions for VCC down to the minimum supply voltage and
are guaranteed to operate for data rates up to 250kbps.
The UART and RS-232 functions operate as one device
or independently since the two functions share only
supply and ground connections.
UART
The universal asynchronous receiver transmitter
(UART) interfaces the SPI/QSPI/MICROWIRE-compati-
ble synchronous serial data from a microprocessor (P)
to asynchronous, serial-data communication ports (RS-
232, IrDA). Figure 1 shows the MAX3110E/MAX3111E
functional diagram. Included in the UART function is an
SPI/QSPI/MICROWIRE interface, a baud-rate generator,
and an interrupt generator.
