ICL3227CA

Overview

The Intersil ICL3227CA is a single driver, single receiver RS-232 transceiver designed for operation within a 3.0V to 5.5V power supply range. It supports data rates up to 1 Mbps and features full-duplex communication capability. The device incorporates enhanced automatic powerdown functionality to minimize standby current consumption. It provides ±15kV electrostatic discharge (ESD) protection on the RS-232 lines, ensuring robustness in sensitive environments. The component is housed in an SSOP-16 surface-mount package.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external voltage generation components.
• Automatic powerdown mechanism significantly reduces quiescent current during idle states.
• High ESD tolerance protects interface pins against static discharge events.

Applications

• Portable computing devices requiring low-power serial communication
• Battery-operated industrial control systems
• Embedded systems with limited power budgets

Procurement Notes

Verify the specific suffix designation carefully, as variations such as 'ECAZA' indicate annealing processes or specific packaging configurations that may differ from the base model. Confirm RoHS compliance status and moisture sensitivity levels prior to integration into manufacturing workflows to ensure adherence to assembly standards.

Selection Notes

Select this component when a single-channel RS-232 interface is required with minimal power consumption. Ensure the application environment operates within the specified temperature range of 0°C to +70°C. Verify that the SSOP-16 package footprint aligns with the printed circuit board layout constraints and that the 1 Mbps speed meets the system's data throughput requirements.

Part Context

This part belongs to the ICL32XXE family of low-power RS-232 transceivers manufactured by Intersil, now part of Renesas Electronics. These devices are engineered to replace older, higher-power counterparts while maintaining compatibility with standard RS-232 protocols. The family emphasizes energy efficiency through advanced power management features suitable for modern portable electronics.

Replacement Considerations

Publicly confirmed substitute part numbers for the ICL3227CA are not available in the provided documentation. Engineers should consult official manufacturer cross-reference lists or datasheets for validated alternatives before proceeding with design changes.
