Overview

The SP3232EEA-L is a high-speed RS-232 transceiver designed for portable and battery-powered applications. It operates from a single 3.0V to 5.5V supply using an internal charge pump to generate RS-232 voltage levels without external high-voltage rails. This device supports data rates up to 235kbps while maintaining low power consumption of 0.3mA typical.

Why Choose This Part

The device features an enhanced ESD protection rating and a high-efficiency charge pump requiring only four 0.1uF capacitors. It operates efficiently across a wide 3.0V to 5.5V supply range, making it compatible with both legacy 5V systems and modern 3.3V low-power microcontrollers.

Applications

Portable Diagnostics
Ideal for handheld industrial tools that require a low-power serial interface for data logging and field updates.
Battery-Powered Instruments
Used in battery-operated equipment where the 1uA shutdown current extends standby battery life.
Embedded System Debugging
Provides a reliable RS-232 interface for console access in systems with 3.3V or 5V logic levels.

Getting Started

To implement this part, place four 0.1uF capacitors for the internal charge pump and a 0.1uF bypass capacitor on the Vcc pin. Ensure the RS-232 cable length is minimized for high baud rate operation and verify that the 16-pin SSOP footprint matches your PCB layout for the 0.65mm pitch.
