FAQs

What is MK48T08B-15?

The MK48T08B-15 is a 8K x 8 non-volatile static RAM (NVSRAM) module with a built-in lithium energy source and a 10-year minimum data retention period. It is designed by STMicroelectronics to provide data retention in the absence of power, making it suitable for applications requiring reliable non-volatile memory storage.

How Does MK48T08B-15 Work?

The MK48T08B-15 uses a combination of volatile static RAM and a non-volatile lithium battery to retain data when power is removed. The battery provides backup power to the SRAM when the main power source is off, ensuring that data remains intact. The module seamlessly switches between the main power and the battery to maintain data integrity.

How Many Pins does MK48T08B-15 have and What are the Functions of the Pinout Configuration?

The MK48T08B-15 is typically housed in a 28-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

VCC: Main power supply pin.
GND: Ground pin.
CE, OE: Chip enable and output enable pins, respectively.
WE: Write enable pin.
DS0-DS7: Data input/output pins.
RTC: Real-time clock input/output pin.
VBAT: Lithium battery backup pin.

What are the Pros and Cons of MK48T08B-15?

Pros:

Non-Volatile Memory: Retains data without the need for continuous power supply.
Long Data Retention Period: Offers a minimum 10-year data retention period with the built-in lithium battery.
Integrated Solution: Combines static RAM and battery backup in a single module for ease of implementation.
Reliable Data Storage: Ensures data integrity during power loss or system shutdown.

Cons:

Cost: NVSRAM modules with built-in battery backup may be more expensive than standard SRAM modules.
Self-Discharge: The lithium battery may have a self-discharge rate that needs to be considered for long-term data retention.
Complexity: Requires proper handling of battery replacement and system integration for optimal performance.

Are There Any Equivalents/Alternatives to MK48T08B-15 for Recommendation?

The DS1230Y-120+ from Maxim Integrated is a comparable NVSRAM module with similar features.
Alternative options to the MK48T08B-15 include the FM1608 from Cypress Semiconductor and the DS1742W-120 from Maxim Integrated.
