MAX3107ETG+TG3U

Controllers Overview

The MAX3107ETG+T is a single-channel UART featuring 128-word transmit and receive FIFOs, controlled via SPI or I²C interfaces. It supports data rates up to 24Mbps using 2x and 4x rate modes. The device includes an integrated PLL, prescaler, and fractional baud-rate generator for high-resolution clocking. Supply voltages range from 1.71V to 3.6V for logic and 2.35V to 3.6V for analog sections. Typical supply current is 640µA at 1Mbps with a 20MHz clock. Operating temperature spans -40°C to +85°C. Available in 24-pin TQFN (3.5mm x 3.5mm) and SSOP packages.

Controllers Feature Summary

• Provides automatic hardware and software flow control including RTS/CTS and XON/XOFF
• Includes SIR and MIR compliant IrDA encoder/decoder functionality
• Features logic-level translation on controller and transceiver interfaces down to 1.7V

Controllers Applications

• Portable devices
• Industrial control systems
• Fieldbus networks
• Automotive infotainment systems
• Medical systems

Controllers Procurement Notes

Verify the specific package variant required, as the MAX3107 is available in both 24-pin TQFN and SSOP configurations. Confirm interface compatibility with the host system's SPI or I²C bus speeds. Ensure voltage levels across VA, VL, and VEXT pins match the application design constraints within the specified ranges.

Controllers Selection Notes

Select the appropriate package based on board space constraints, choosing between the compact TQFN or standard SSOP form factor. Consider power consumption requirements when configuring sleep and shutdown modes. Verify that the selected baud-rate generator settings align with the available reference clock frequencies for optimal performance.

Controllers Part Context

The MAX3107 belongs to the Maxim Integrated MAX3107 family of advanced UARTs. It shares register compatibility with related parts such as the MAX3108, MAX3109, and MAX14830. This allows for potential pin-to-pin or register-compatible upgrades in existing designs requiring similar serial communication capabilities.

Controllers Replacement Considerations

The MAX3107 is register compatible with the MAX3108, MAX3109, and MAX14830. These parts may serve as functional substitutes if they meet the specific voltage and package requirements of the design.
