PT7C4563WE

Real Time Clock Overview

The PT7C4563WE is a Real-Time Clock (RTC) module manufactured by Diodes Incorporated. It features an I2C bus interface and utilizes Binary-Coded Decimal (BCD) formats for both date and time data. The device operates within a supply voltage range of 1.3 V to 5.5 V and is housed in an 8-SOIC package with a width of 0.154 inches (3.90 mm). It supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

• I2C/SMBus compatible bus interface
• BCD format for time and date registers
• Wide operating voltage range: 1.3 V to 5.5 V
• 8-SOIC surface-mount package

Real Time Clock Applications

• General-purpose clock/calendar systems
• Industrial control equipment requiring time stamping
• Consumer electronics with real-time tracking needs

Real Time Clock Procurement Notes

Verify the specific suffix 'WE' against the official Diodes Incorporated datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target system's I2C voltage levels, as the device supports a wide input range from 1.3 V to 5.5 V. Confirm that the industrial temperature grade (-40°C to +85°C) meets the operational environment requirements.

Real Time Clock Selection Notes

Select this component when an I2C-connected RTC is required in an 8-SOIC footprint. The wide voltage tolerance allows integration into systems ranging from low-power battery-operated devices to 5V logic systems. Verify that the BCD output format aligns with the microcontroller's decoding capabilities or software library support.

Real Time Clock Part Context

The PT7C4563WE belongs to the PT7C4563C series of Real-Time Clock modules. This family provides basic timekeeping and calendar functions via a standard serial interface. The 'WE' suffix typically denotes the SOIC-8 package variant within this product line, distinguishing it from TSSOP or other form factors available in the same series.

Real Time Clock Replacement Considerations

Direct pin-to-pin replacements may include other I2C RTCs in 8-SOIC packages such as the PCF8563 or DS1302 variants, provided the voltage and interface protocols match. Cross-reference the register map and alarm functionality if specific interrupt features are utilized in the design.
