Overview
MAX3110E/MAX3111E SPI/MICROWIRE-Compatible UART and ±15kV ESD-Protected RS-232 Transceivers with Internal Capacitors General Description The MAX3110E/MAX3111E combine a full-featured universal asynchronous receiver/transmitter (UART) with ±15kV ESD-protected RS-232 transceivers and integrated charge-pump capacitors into a single 28-pin package for use in space-, cost-, and power-constrained 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 performance down to VCC = +3V (+4.
5V for MAX3110E) while consuming only 600µA.
The receivers remain active in a hardware/software-invoked shutdown, allowing 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-programmable divider ratios for all common baud rates from 300baud to 230kbaud.
The UART features an 8word-deep receive FIFO that minimizes processor overhead 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).
