ST3232EBWR Low Power 2 Driver/2 Receiver RS-232 Interface IC

The ST3232EBWR is a robust, low-power transceiver for RS-232 communication from STMicroelectronics, designed to provide reliable data transmission and reception in a compact package. This product is particularly suitable for applications where power efficiency and space constraints are critical considerations.

Operating from a single 3.0V to 5.5V power supply, this device features two drivers and two receivers, making it an ideal choice for bidirectional communication in portable or battery-operated devices. The ST3232EBWR is capable of operating at data rates up to 400 kbps, ensuring swift data exchange for a wide range of applications, from industrial to consumer electronics.

One of the key attributes of the ST3232EBWR is its low-power consumption. It draws a mere 300 µA of supply current when unloaded or fully loaded with the drivers disabled, and it provides a low-power shutdown mode that reduces the current draw to a negligible 1 µA, further conserving energy when the interface is not in use.

The device incorporates an efficient charge pump circuitry that eliminates the need for an external power supply for the driver outputs, which can swing from +5.5V to -5.5V, ensuring compatibility with a broad range of peripherals. This feature simplifies design and reduces the overall bill of materials.

Safety and protection are paramount in electronic design, and the ST3232EBWR addresses this with its ESD protection exceeding IEC 1000-4-2 Level 4 standards, providing resilience against electrostatic discharges. Additionally, the transceiver's drivers and receivers are protected against ±15kV ESD hits, safeguarding the device in harsh environments.

The ST3232EBWR comes in a space-saving 16-pin wide body SOIC package, making it amenable for use in compact systems without compromising on functionality or performance. Its industrial temperature range of -40°C to +85°C ensures reliable operation across various environmental conditions.

In summary, the ST3232EBWR from STMicroelectronics is a versatile, low-power RS-232 transceiver that combines high data rate capability, power efficiency, and robust protection features in a small package, suitable for a wide array of applications.
