MAX3110ECWI

Controllers Overview

The MAX3110ECWI is a single-chip solution integrating a universal asynchronous receiver/transmitter (UART) with RS-232 transceivers and internal charge-pump capacitors. It operates on a +5V supply within the commercial temperature range of 0°C to +70°C. The device features an SPI/QSPI/MICROWIRE-compatible serial interface, reducing microcontroller I/O requirements. It supports data rates up to 230kbps for UART operations and 250kbps for RS-232 transmission. The package is a 28-pin Wide SOIC.

Controllers Feature Summary

• Integrates a full-featured UART with an RS-232 transceiver in a single 28-pin package

• Industrial Front-Panel Interfaces
• Hand-Held/Battery-Powered Equipment

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets the required environmental operating conditions for the intended application environment before finalizing procurement decisions.

Controllers Selection Notes

Select this component when space and power constraints are critical due to its integrated design. It is suitable for applications requiring true RS-232 performance at lower supply voltages compared to traditional solutions. Consider the SPI interface compatibility with the host microcontroller to ensure seamless integration.

Controllers Part Context

This part belongs to the MAX3110E/MAX3111E family from Analog Devices Inc./Maxim Integrated. It is designed as a cost-effective alternative to discrete UART and RS-232 transceiver combinations, offering reduced board space and simplified design complexity for embedded systems.

Controllers Replacement Considerations

The MAX3110E/MAX3111E are hardware- and software-compatible with the MAX3100 and MAX3222E. Verify pinout and register compatibility when substituting these parts.
