ST3232ECWR

Drivers, Receivers, Transceivers Overview

The ST3232ECWR is a low-power RS-232 transceiver from the ST3232E series, manufactured by STMicroelectronics. It operates on a single 3 V to 5.5 V supply and features two drivers and two receivers with ±15 kV human body model ESD protection. The device guarantees data rates up to 250 kbps and utilizes a dual charge pump requiring four 0.1 µF external capacitors. It is housed in an SO-16 Large package (tape and reel) and supports an operating temperature range of 0 °C to 70 °C.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection for RS-232 I/O pins
• Low power consumption with proprietary low-dropout transmitter output stage
• Dual charge pump circuit requiring minimal external capacitance

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Subnotebook and palmtop computers
• Battery-powered equipment
• Hand-held equipment
• Peripherals and printers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code ST3232ECWR against official STMicroelectronics documentation to confirm the SO-16 Large package variant. Ensure that the required operating temperature range of 0 °C to 70 °C aligns with your system specifications. Cross-reference the datasheet revision history to validate current manufacturing status and any potential material or process changes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing serial communication interfaces for portable devices requiring low power consumption. The integrated charge pump eliminates the need for external voltage inversion circuits, simplifying board layout. Verify that the application environment remains within the specified 0 °C to 70 °C temperature range and that the 250 kbps data rate meets the system's throughput requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ST3232E family, which includes variants like ST3232ECN and ST3232EBDR. The 'EC' suffix indicates commercial temperature range operation, while 'WR' specifies the SO-16 Large package with tape and reel packaging. This distinguishes it from industrial grade parts and different packages such as DIP-16 or TSSOP16.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other ST3232E series parts with matching electrical characteristics. Consider ST3232ECDR for standard SO-16 packaging or ST3232ECTR for TSSOP16 packaging if pin compatibility allows. Verify that alternative packages maintain the same pin configuration and electrical performance parameters.
