MAX3110EENI+G36

Controllers Overview

The MAX3110EENI+G36 is a single-chip UART and RS-232 transceiver in a 28-pin Wide SO package. It integrates an SPI/QSPI/MICROWIRE-compatible UART with an internal crystal oscillator, baud-rate generator, and 8-word receive FIFO. The device includes two RS-232 drivers and receivers with ±15kV ESD protection and internal charge-pump capacitors. Operating at VCC = +5V, it supports data rates up to 230kbps for standard UART and 250kbps for the RS-232 interface. Supply current is 600µA, reducing to 10µA during shutdown.

Controllers Feature Summary

• Integrates a full-featured UART and RS-232 transceiver into a single 28-pin package to minimize board space.
• Features an SPI/QSPI/MICROWIRE-compatible serial interface that reduces microcontroller I/O pin usage.
• Includes internal charge-pump capacitors, eliminating the need for external components.
• Provides true RS-232 performance down to +3V supply voltage while maintaining low power consumption.

Controllers Applications

• Point-of-Sale (POS) Devices
• Handy-Terminals
• Telecom/Networking Diagnostic Ports
• Industrial Front-Panel Interfaces
• Hand-Held/Battery-Powered Equipment

Controllers Procurement Notes

Verify the component matches the specific ordering code MAX3110EENI+G36 against official manufacturer documentation. Confirm the package type is 28-pin Wide SO and the temperature range is 0°C to +70°C. Ensure the suffix G36 corresponds to lead-free and RoHS compliance as defined by the supplier's specifications.

Controllers Selection Notes

Select this component when space-constrained designs require both UART logic and RS-232 signaling. It is suitable for applications needing SPI or MICROWIRE interfaces to save microcontroller pins. Consider the 5V supply requirement and the integrated charge pump for simplified circuit design without external capacitors.

Controllers Part Context

This part belongs to the MAX3110E/MAX3111E family of devices from Analog Devices Inc./Maxim Integrated. The MAX3110E variant operates at +5V, while the MAX3111E operates at +3.3V. Both share identical functionality and pinouts, differing primarily in their operating supply voltage ranges.

Controllers Replacement Considerations

The datasheet notes hardware and software compatibility with the MAX3100 and MAX3222E. Verify pinout and register compatibility before substituting these parts. No other direct substitute part numbers are confirmed in the provided documentation.
