ICL3221ECAZA-T

Overview

The ICL3221ECAZA-T is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates from a single +3V to +5.5V supply and supports data rates up to 120kbps. The device integrates charge pumps that generate ±6V from the single supply, eliminating the need for external components. It features enhanced automatic powerdown circuitry to reduce current consumption during idle periods. The component is housed in an 8-pin SOIC package.

Feature Summary

• Integrated charge pump eliminates requirement for external capacitors
• Enhanced automatic powerdown reduces quiescent current during idle states
• Single-supply operation compatible with low-voltage logic systems

Applications

• Portable battery-powered equipment requiring low power consumption
• Industrial control systems utilizing RS-232 communication
• Modem interfaces and serial port implementations

Procurement Notes

Verify the manufacturer date code and lot traceability against the official Renesas datasheet specifications. Confirm the presence of the 'T' suffix indicates tape-and-reel packaging. Ensure the ECAZA designation matches the required temperature range and package variant for your specific design implementation.

Selection Notes

Select this component when designing systems requiring a single-supply RS-232 interface without external boost converters. It is suitable for applications where board space is limited due to the integrated charge pump. Compare pinout compatibility with existing designs if replacing legacy dual-supply transceivers.

Part Context

This part belongs to the ICL3221 family of RS-232 transceivers. It shares functional similarities with other Intersil/Renesas parts like the ICL3221IAZ but differs in package type and operating temperature range. The family is characterized by low power consumption and robust ESD protection.

Replacement Considerations

Publicly confirmed substitutes include the ICL3221IAZ and ICL3221EIBZ. Verify pin compatibility and electrical parameters before substitution.
