FAQs

What is RTC-4543SA?

The RTC-4543SA is a real-time clock (RTC) module designed by Epson. It is used for timekeeping and scheduling in various electronic devices, such as appliances, industrial equipment, and automotive systems.

How Does RTC-4543SA Work?

The RTC-4543SA functions by accurately tracking time and date information using an internal crystal oscillator. It maintains timekeeping even when the main power source is disconnected by relying on a backup battery. The module typically communicates with a microcontroller or host system through a serial interface for setting and reading time data.

How Many Pins does RTC-4543SA have and What are the Functions of the Pinout Configuration?

The RTC-4543SA is housed in a small package with a pinout configuration that includes:

  • VCC: Main power supply pin.
  • GND: Ground pin.
  • SCL: Serial clock line for communication.
  • SDA: Serial data line for communication.
  • VBAT: Backup battery supply pin.
  • IRQ: Interrupt output pin for alerting the host of specific events.

What are the Pros and Cons of RTC-4543SA?

Pros:

  • Accurate Timekeeping: Provides precise time and date information for synchronized operations.
  • Battery Backup: Maintains timekeeping functionality during power outages or when the main power source is off.
  • Serial Interface: Allows for easy integration with microcontrollers and other host systems.
  • Compact Size: Small form factor suitable for space-constrained designs.

Cons:

  • Limited Features: May not have advanced functionalities compared to higher-end RTC modules.
  • Configuration Complexity: Requires proper initialization and setting of time parameters for correct operation.

Are There Any Equivalents/Alternatives to RTC-4543SA for Recommendation?

  • The DS3231 from Maxim Integrated is a popular alternative RTC module with similar timekeeping capabilities.
  • Alternatives to the RTC-4543SA include the PCF8523 from NXP and the MCP79410 from Microchip Technology.
