SP3225ECA-L

Drivers, Receivers, Transceivers Overview

The SP3225ECA-L is a MaxLinear RS-232 transceiver featuring two drivers and two receivers. It operates from a +3.0V to +5.5V supply and supports a high-speed data rate of 1 Mbps. The device includes an internal charge pump requiring four external capacitors, providing ±5.5V outputs. It features Auto On-line® Plus for automatic power saving and offers 15kV ESD protection on I/O pins. Available in a 20-pin SSOP package, it meets EIA/TIA-232-F standards.

Drivers, Receivers, Transceivers Feature Summary

• Auto On-line® Plus automatically manages power states by entering low-power shutdown during idle periods and waking upon signal activity without software intervention.
• Integrated regulated charge pump generates stable RS-232 voltage levels from a single low-voltage power supply using minimal external capacitance.
• High-speed data transfer capability up to 1 Mbps with unrestricted slew rates for rapid signal transitions.
• Robust input protection with 15kV ESD ratings on RS-232 I/O pins ensures reliability in electrically noisy environments.

Drivers, Receivers, Transceivers Applications

• Diagnostic and serial ports on embedded applications
• Handheld test equipment
• PC-related peripherals and equipment
• Battery-powered equipment
• Point-of-sale equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the operating temperature range matches the 'EC' designation (0°C to +70°C). Ensure the package type corresponds to the 20-SSOP form factor required for the target PCB layout. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 2-driver/2-receiver configuration is required alongside high-speed 1 Mbps transmission capabilities. It is suitable for designs needing automatic power management via Auto On-line® Plus to extend battery life. Verify that the system operates within the +3.0V to +5.5V supply range and requires 15kV ESD protection on serial interfaces.

Drivers, Receivers, Transceivers Part Context

The SP3225E belongs to the SP3224E-SP3227E family of intelligent RS-232 transceivers manufactured by MaxLinear (formerly Exar). This series shares common features like the patented charge pump and Auto On-line® Plus technology. The SP3225E specifically differentiates itself within the family by offering 1 Mbps speed compared to the 250 kbps of the SP3224E, while maintaining the same 2-driver/2-receiver architecture.

Drivers, Receivers, Transceivers Replacement Considerations

Public documentation confirms drop-in replacement compatibility with MAX3225, ICL3225, MAX3226, ICL3226, MAX3227, and ICL3227 devices. Verify pinout alignment and electrical parameter equivalence before substitution.
