STMicroelectronics MK48Z02B-12 Non-Volatile SRAM

The MK48Z02B-12 is a 16Kbit (2K x 8) zero-power™ SRAM manufactured by STMicroelectronics. This innovative product combines the convenience of static RAM with a non-volatile storage component, ensuring data retention without the need for a power source. It is particularly designed for applications requiring data preservation upon power loss, making it an ideal choice for critical data storage in various electronic systems.

One of the key features of the MK48Z02B-12 is its zero-power functionality. This is achieved through the integration of a small lithium battery within the device, which maintains the data stored in the memory when external power is not available. The battery has a long life, ensuring that data is retained for an extended period without the need for external power.

The device operates with a supply voltage of 4.5V to 5.5V, and its access time of 120ns makes it suitable for high-performance applications. The MK48Z02B-12 is organized as 2,048 words by 8 bits, providing a total storage capacity of 16Kbits. This capacity is ideal for storing configuration parameters, small look-up tables, or any other data that must be preserved during power-down scenarios.

STMicroelectronics has designed the MK48Z02B-12 with reliability in mind. It features automatic power-fail chip deselect and write protection, ensuring that data integrity is preserved even during unexpected power interruptions. This makes the MK48Z02B-12 highly reliable for industrial, automotive, and other mission-critical applications where data loss is not an option.

The packaging of the MK48Z02B-12 is also noteworthy. It comes in a 24-pin DIP (Dual In-line Package), which is a standard through-hole mounting package, making it easy to integrate into a wide range of circuit boards. This package type also allows for easy replacement or removal, which can be particularly valuable in maintenance or upgrade situations.

In summary, the STMicroelectronics MK48Z02B-12 offers a unique combination of volatile and non-volatile memory functions, robust data protection features, and a convenient form factor, making it a versatile and reliable choice for storing critical data in electronic systems.
