PT7C4311AZEEX

Real Time Clock Overview

The PT7C4311AZEEX is a low-power Real-Time Clock (RTC) integrated circuit manufactured by Diodes Incorporated. It features an I2C bus interface for communication and includes 56 bytes of non-volatile RAM for data storage. The device supports leap year compensation automatically through the year 2099 and provides a square wave output signal. It operates within a supply voltage range of 1.2V to 5.5V and is available in an 8-WFDFN package with exposed pad, suitable for space-constrained applications requiring precise timekeeping.

Real Time Clock Feature Summary

• I2C Bus Interface: Serial communication via two-wire I2C protocol.
• Non-Volatile Memory: Integrated 56-byte NVRAM for user data retention.
• Low Power Consumption: Designed for battery-backed or energy-efficient systems.
• Calendar Functionality: Automatic leap year compensation up to 2099.

Real Time Clock Applications

• Portable electronic devices requiring accurate timekeeping.
• Battery-powered IoT sensors and modules.
• Data logging systems needing timestamp capabilities.
• Consumer electronics with calendar functions.

Real Time Clock Procurement Notes

Verify the specific suffix 'AZEEX' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the target system's I2C voltage levels and address configuration before procurement.

Real Time Clock Selection Notes

Select this component when a small footprint RTC with integrated NVRAM is required. Compare current consumption at the operating voltage against other models in the PT7C43xx series if ultra-low power is critical. Confirm the 8-WFDFN package fits the PCB layout constraints.

Real Time Clock Part Context

This part belongs to the PT7C43xx family of real-time clocks from Diodes Incorporated. It shares functional similarities with variants like PT7C4311ZEEX but differs in packaging and potentially minor electrical characteristics. It serves as a drop-in replacement for legacy RTCs in designs requiring I2C connectivity and onboard memory.

Real Time Clock Replacement Considerations

Check pin-to-pin compatibility with existing designs using similar RTCs. Verify that the I2C address and register map are identical to any previously used components to avoid firmware modifications.
