MAX3230AEEWV+

Overview

The MAX3230AEEWV+ is a dual line transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for RS-232 communication protocols. It operates within a supply voltage range of 2.5V to 5.5V and supports data rates up to 250kbps. The device features full duplex transmission with two drivers and two receivers. It utilizes a 30-WLP (Wafer Level Package) form factor, specifically identified as 30-WFBGA or WLBGA in supplier documentation. The component is rated for an operating temperature range from -40°C to +85°C and includes a receiver hysteresis of 500 mV.

Feature Summary

• Integrated dual driver and dual receiver architecture for full-duplex RS-232 signaling
• Capable of operation across a wide single-supply voltage range from 2.5V to 5.5V
• Utilizes compact wafer-level packaging to minimize board space requirements

Applications

• Portable battery-powered devices requiring low-voltage RS-232 connectivity
• Industrial control systems utilizing serial communication interfaces
• Embedded systems integrating modem or peripheral connections

Procurement Notes

Verify the specific suffix EWV+ against the target datasheet revision to ensure package compatibility. Confirm that the 30-WLP footprint matches the PCB layout constraints. Check current part status as availability may vary between distributors. Ensure the voltage domain aligns with the 2.5V to 5.5V specification before integration into the design.

Selection Notes

Select this component when a small form factor is required for dual-channel RS-232 applications. It is suitable for designs operating below the standard 3.0V minimum of some legacy counterparts. Consider the 30-WLP package for high-density layouts where traditional SOIC or SSOP packages are too large. Verify thermal performance within the specified -40°C to +85°C industrial range.

Part Context

This part belongs to the MAX3230 series of true RS-232 transceivers. It shares functional similarities with other Maxim Integrated RS-232 components but distinguishes itself through its specific wafer-level packaging and extended low-voltage operation starting at 2.5V. It serves as a specialized interface solution for compact electronic systems.
