Description and Introduction

PCF8593; Low power clock/calendar # Introduction to the PCF8593T/1 Electronic Component  

The PCF8593T/1 is a low-power CMOS real-time clock (RTC) and calendar integrated circuit designed for timekeeping applications. Manufactured by NXP Semiconductors, this component provides accurate time and date functions while consuming minimal power, making it suitable for battery-operated devices such as smart meters, medical equipment, and portable electronics.  

Featuring a built-in 32.768 kHz oscillator, the PCF8593T/1 maintains precise timekeeping with automatic leap-year compensation. It supports both 12-hour and 24-hour time formats and includes alarm functionality, allowing for event-triggered operations. The device communicates via an I²C-bus interface, ensuring easy integration with microcontrollers and other digital systems.  

With a wide operating voltage range (1.8V to 5.5V), the PCF8593T/1 is versatile for various embedded applications. Its low standby current makes it ideal for energy-efficient designs. Additionally, the component includes a programmable clock output and power-fail detection, enhancing system reliability.  

Compact and robust, the PCF8593T/1 is available in an SO8 package, offering a balance of performance and space efficiency. Whether used in industrial automation or consumer electronics, this RTC provides dependable timekeeping with minimal power consumption.

Alternative Part Number

  • DS1307Z+ --: I2C real-time clock in SOIC-8 with similar function and pinout, widely available and well documented.
  • M41T00M6F --: I2C serial real-time clock in SOIC-8, functionally comparable to the PCF8593 with similar register interface.
  • PCF8563T/5,518 --: NXP I2C real-time clock in SOIC-8, same vendor lineage as Philips and a common drop-in functional replacement.
  • DS1307Z+ --: I2C real-time clock in an SOIC-8 package, functionally similar to the PCF8593T, widely available and well documented.
  • M41T00M6F --: I2C serial real-time clock with similar register-based operation and SOIC-8 footprint, a common drop-in style alternative.
  • RV-8564-C3 --: Low-power I2C real-time clock module offering comparable timekeeping functions for designs migrating away from the PCF8593.
