MAX3100EPD+

Controllers Overview

The MAX3100EPD+ is a universal asynchronous receiver/transmitter (UART) optimized for microcontroller-based systems, manufactured by Analog Devices Inc./Maxim Integrated. It interfaces via an SPI/MICROWIRE-compatible bus and operates within a supply voltage range of +2.7V to +5.5V. The device features an 8-word FIFO buffer, software-programmable baud rates from 300 to 230k bps, and IrDA SIR timing compatibility. It supports interrupt generation with four maskable sources, including address recognition on 9-bit networks. The component is housed in a 14-pin plastic DIP package and is rated for an extended operating temperature range of -40°C to +85°C.

Controllers Feature Summary

• +2.7V to +5.5V Supply Voltage in Operating Mode
• Schmitt-Trigger Inputs for Opto-Couplers

Controllers Applications

• Handheld Instruments
• Intelligent Instrumentation
• UART in SPI Systems
• Small Networks in HVAC or Building Control
• Isolated RS-232/RS-485: Directly Drives Opto-Couplers

Controllers Procurement Notes

Verify the specific suffix 'EPD+' indicates the lead-free/RoHS-compliant version in the 14-pin Plastic DIP package. Confirm the extended temperature rating (-40°C to +85°C) matches the application requirements. Ensure the ordering information aligns with the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Controllers Selection Notes

Select this component when a low-power UART bridge is required for resource-constrained embedded systems. The MAX3100EPD+ is suitable for applications needing direct opto-coupler driving capabilities due to its high sink currents. Consider the 14-pin DIP package if through-hole assembly is necessary. Evaluate the need for IrDA timing support if infrared communication is part of the system design.

Controllers Part Context

The MAX3100 series includes variants such as the MAX3100EEE+ (QSOP-16), MAX3100ETG+ (TQFN-EP), and commercial temperature versions like the MAX3100CPD+. The EPD suffix specifically denotes the 14-pin plastic DIP package with RoHS compliance. All variants share the same core functionality but differ in physical footprint and thermal performance characteristics.
