MAX3110ECNI+G36

Controllers Overview

The MAX3110ECNI+G36 is a UART interface IC combining a universal asynchronous receiver/transmitter with RS-232 transceivers in a 28-pin Plastic DIP package. It operates on a single +5V supply within the commercial temperature range of 0°C to +70°C. The device supports data rates up to 250 kbps and features an SPI/QSPI/MICROWIRE-compatible serial interface. Key electrical parameters include a maximum supply voltage of 5.5V, minimum supply voltage of 4.5V, and typical operating current of 600µA. It includes an 8-byte receive FIFO and provides ±15kV ESD protection.

Controllers Feature Summary

• Integrates a full-featured UART with RS-232 transceivers and internal charge-pump capacitors into a single package
• Features an SPI/QSPI/MICROWIRE-compatible serial interface to reduce microcontroller I/O pin usage
• Provides true RS-232 performance down to low supply voltages while maintaining low power consumption
• Includes hardware and software shutdown modes to minimize power dissipation

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 specific suffix 'CN' indicates the 28-pin Plastic DIP package and commercial temperature range. Confirm '+G36' denotes lead-free status and RoHS compliance. Check for obsolescence or lifecycle status as this component may be discontinued. Ensure the ordering information matches the exact manufacturer part number before purchase.

Controllers Selection Notes

Select this component when space-constrained designs require both UART logic and RS-232 signaling without external charge-pump capacitors. It is suitable for applications needing SPI or MICROWIRE control interfaces. Verify that the +5V supply requirement aligns with the system power architecture. Consider the Plastic DIP package if through-hole mounting is required for the specific application environment.

Controllers Part Context

This device belongs to the MAX3110E/MAX3111E series from Analog Devices/Maxim Integrated. It is hardware and software compatible with the MAX3100 and MAX3222E. The MAX3110E variant specifically requires a +5V supply, distinguishing it from the MAX3111E which supports +3.3V operation. The ECNI suffix identifies the commercial grade and DIP packaging.
