FAQs

What is DS1284+?

The DS1284+ is a nonvolatile timekeeping RAM (NVTRAM) module designed by Maxim Integrated. It combines the functionality of a real-time clock (RTC) and nonvolatile memory, making it suitable for applications requiring timekeeping and data storage, such as industrial automation, medical devices, and consumer electronics.

How Does DS1284+ Work?

The DS1284+ works by providing timekeeping functions using the integrated RTC with battery backup, ensuring accurate timekeeping even during power interruptions. Additionally, it includes nonvolatile memory for data storage, allowing critical information to be retained across power cycles. The module communicates with the host microcontroller through a simple serial interface, enabling easy integration into existing systems.

How Many Pins does DS1284+ have and What are the Functions of the Pinout Configuration?

The DS1284+ is housed in a 28-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VCC: Power supply pin.
  • GND: Ground pin.
  • CE, OE, WE: Control pins for chip enable, output enable, and write enable, respectively.
  • RTC Register Address/Data, RAM Address/Data: Serial interface pins for RTC and nonvolatile RAM communication.
  • VBAT: External battery input for RTC backup.

What are the Pros and Cons of DS1284+?

Pros:

  • Integrated Timekeeping and Memory: Provides both real-time clock and nonvolatile memory functions in a single module, reducing component count and board space.
  • Battery Backup: Ensures reliable timekeeping and data retention during power loss or system shutdown.
  • Simple Serial Interface: Easy integration with microcontrollers and other digital systems.
  • High Reliability: Designed for industrial and automotive applications with robust performance and data retention.

Cons:

  • Complexity: Configuring and managing nonvolatile memory may add complexity to the system firmware.
  • Cost: Integrated NVTRAM modules may have a higher cost compared to separate RTC and memory components.
  • Package Size: The 28-pin SOIC package may require more board space than smaller alternatives.

Are There Any Equivalents/Alternatives to DS1284+ for Recommendation?

  • The DS1744 from Maxim Integrated offers similar NVTRAM functionality with additional features.
  • Alternatives to the DS1284+ include the M41ST87W from STMicroelectronics and the MCP7940N from Microchip Technology.
