FAQs

What is DS1644+120?

The DS1644+120 is a non-volatile static RAM (NVSRAM) module designed by Maxim Integrated. It combines the features of a static RAM and non-volatile EEPROM, providing data retention even when power is lost. This makes it suitable for applications requiring continuous, reliable data storage and retrieval.

How Does DS1644+120 Work?

The DS1644+120 utilizes a combination of volatile static RAM cells and non-volatile EEPROM cells. When powered, the device operates like a standard static RAM, offering fast read and write access. During power loss, the contents of the RAM are automatically transferred to the non-volatile EEPROM, ensuring data retention. Upon power restoration, the original data is loaded back into the RAM for seamless operation.

How Many Pins does DS1644+120 have and What are the Functions of the Pinout Configuration?

The DS1644+120 is housed in a 28-pin PDIP (Plastic Dual In-Line Package) package. The pinout configuration includes:

  • VCC: Power supply pin.
  • GND: Ground pin.
  • CE: Chip Enable input pin.
  • OE: Output Enable input pin.
  • WE: Write Enable input pin.
  • AD0-AD7: 8-bits of address/data input/output pins.
  • WP: Write Protect input pin.
  • NC: No connect pin.
  • NC: No connect pin.
  • VBAT: Battery backup input pin.
  • VSS: Ground pin.

What are the Pros and Cons of DS1644+120?

Pros:

  • Non-Volatile Data Storage: Retains data even during power loss, eliminating the need for a separate backup system.
  • Fast Access: Operates as a fast static RAM during normal operation for quick data access.
  • Seamless Power Transition: Automatically transfers data to non-volatile memory upon power loss and restores it upon power restoration.
  • Battery Backup: Supports external battery backup for extended data retention.
  • Wide Operating Voltage: Operates within a wide voltage range, suitable for various applications.

Cons:

  • Cost: NVSRAM modules such as the DS1644+120 may have a higher cost compared to standard volatile SRAM.
  • Package Size: The 28-pin PDIP package may require more board space compared to smaller footprint packages.

Are There Any Equivalents/Alternatives to DS1644+120 for Recommendation?

  • The M48Z02 from STMicroelectronics is a similar NVSRAM module with comparable features.
  • Alternatives to the DS1644+120 include the DS1233 from Maxim Integrated and the FM1608 from Cypress Semiconductor.
