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-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 VCC= +3V (+4.5V for MAX3110E) while consuming only 600µA. The MAX3110E/MAX3111E 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-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).
