The MAX3221CUE+ is a highly-integrated serial port transceiver from Maxim Integrated, designed to facilitate communication between a microcontroller and a serial device. This device is part of Maxim's family of transceivers for RS-232 communication protocol, offering a convenient and reliable solution for applications requiring serial connectivity.

Key Features

• Integrated Charge Pump: The transceiver includes an onboard charge pump circuit that generates the necessary RS-232 voltage levels (+/-10V) from a single 3.0V to 5.5V supply, eliminating the need for multiple power supplies.
• Low-Power Operation: Designed for low-power consumption, the MAX3221CUE+ enters a 1µA shutdown mode when not in use, making it ideal for battery-powered and portable applications.
• High Data Rate: It supports data rates up to 250kbps, ensuring fast and efficient data transfer for a wide range of serial communication needs.
• Electrostatic Discharge (ESD) Protection: The device offers enhanced ESD protection up to ±15kV, safeguarding the transceiver against static electricity and other voltage spikes that can occur during handling or operation.
• Single Receiver and Transmitter: The MAX3221CUE+ features one driver and one receiver, which are fully compliant with the TIA/EIA-232-F standard.
• Small Form Factor: Housed in a compact 16-pin TSSOP package, this transceiver is suitable for space-constrained applications.

Applications

The MAX3221CUE+ is versatile and can be used in a variety of applications, including:

• Portable and handheld devices
• Point-of-sale (POS) terminals
• Data logging and telemetry systems
• Industrial control and automation
• Notebook, tablet, and laptop computers
• GPS receivers
