MAX3111EENI

SPI / MICROWIRE兼容的UART及【 15kV的ESDProtected RS - 232收发器，内置电容器 SPI/MICROWIRE-Compatible UART and ±15kV ESDProtected RS-232 Transceivers with Internal Capacitors

General Description

The MAX3110E/MAX3111E combine a full-featured uni versal 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.
