The SP232ECN is a RS-232 transceiver manufactured by Sipex Corporation (now Exar Corporation, which was later acquired by MaxLinear). It is a single-chip solution for converting CMOS/TTL signals to RS-232 voltage levels, and vice-versa. The SP232ECN is designed for applications requiring serial communication, such as connecting a microcontroller or other digital device to a computer or other RS-232 compatible equipment. It typically operates from a single 5V power supply and includes internal charge pumps to generate the ±10V RS-232 voltage levels required for transmission.

Applications:

• Serial communication interfaces
• Connecting microcontrollers to PCs
• Industrial control systems
• Point-of-sale (POS) terminals
• Data acquisition systems

Features:

• Meets or exceeds TIA/EIA-232-F standards
• Operates from a single 5V power supply
• Requires only 4 external capacitors
• High data rate
• Low power operation
• Built-in charge pump for generating RS-232 voltage levels
• Available in various package options (e.g., DIP, SOIC)

Benefits:

• Simplified RS-232 Interface: Integrated charge pumps eliminate the need for external high-voltage power supplies.
• Reduced Component Count: Minimal external components required, simplifying board layout and reducing cost.
• Reliable Communication: Meets industry-standard specifications for robust and reliable RS-232 communication.
• Low Power Consumption: Ideal for battery-powered or energy-efficient applications.
• Easy Integration: Compatible with a wide range of microcontrollers and digital logic devices.

Specifications:

The SP232ECN typically supports data rates up to 120 kbps. The supply voltage is typically 5V. The transceiver meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 standards. Input voltage thresholds and output voltage levels are compliant with RS-232 specifications. Refer to the product datasheet for detailed electrical characteristics and application information.
