FAQs

What is DS1216C?

The DS1216C is a nonvolatile controller integrated circuit (IC) designed by Maxim Integrated. It is specifically designed for use with external static RAM (SRAM) to create a fully static nonvolatile RAM (NVSRAM) that retains data when power is removed. The DS1216C is ideal for applications requiring reliable nonvolatile memory, such as data logging, industrial automation, and battery-backed memory systems.

How Does DS1216C Work?

The DS1216C works by interfacing with an external SRAM to save its contents to an internal nonvolatile memory array whenever the external power is removed. When power is restored, the DS1216C automatically restores the contents of the external SRAM from the nonvolatile memory, ensuring data integrity and retention. It provides a seamless data backup solution for critical applications.

How Many Pins does DS1216C have and What are the Functions of the Pinout Configuration?

The DS1216C is available in various package options, including DIP (Dual Inline Package) and SOIC (Small Outline Integrated Circuit). The pinout configuration typically includes:

VCC: Power supply pin.
GND: Ground pin.
CE1, CE2: Chip enable inputs.
WE: Write enable input.
OE: Output enable input.
NC: No connect pin (may vary depending on package type).
Address, Data, Control: Pins for interfacing with the external SRAM.
NVCTR: Nonvolatile control input.
VBAT: Battery input for backup power.

What are the Pros and Cons of DS1216C?

Pros:

Nonvolatile Back-Up: Provides reliable data retention during power loss.
Easy Integration: Interfaces seamlessly with external SRAM to create nonvolatile memory without external components.
Automatic Operation: Automatically saves and restores data without user intervention.
Versatile: Available in different package options for flexibility in system design.

Cons:

External SRAM Dependency: Requires an external SRAM to function as nonvolatile memory.
Battery Requirement: Requires a backup battery for nonvolatile operation.

Are There Any Equivalents/Alternatives to DS1216C for Recommendation?

The DS1245 from Maxim Integrated is a similar nonvolatile controller with additional features such as a real-time clock and calendar.
Alternatives to the DS1216C include the FM1608 from Cypress Semiconductor and the M48Z02 from STMicroelectronics.
