The TBP28S42N is a high-performance, nonvolatile static RAM integrated circuit designed by Texas Instruments, one of the leading manufacturers in the semiconductor industry. This innovative memory chip offers a unique combination of volatile and nonvolatile memory, ensuring data retention without the need for a battery backup system. It is particularly suitable for applications where data must be preserved across power cycles or in the event of a power failure.

The TBP28S42N features a storage capacity of 16,384 bits, organized as 2,048 words by 8 bits. This configuration allows for efficient data storage and retrieval, making it an excellent choice for a wide range of computing and digital processing applications. The device operates over a wide voltage range, typically 4.5V to 5.5V, which ensures compatibility with most 5V logic families and provides a stable and reliable performance across various operating conditions.

One of the key attributes of the TBP28S42N is its access time of 45ns, which enables fast read and write operations. This rapid access time is crucial for applications that require quick data processing and can significantly improve system performance. Additionally, the nonvolatile element of the SRAM is implemented using Texas Instruments' advanced floating-gate technology, which provides a high level of data integrity and reliability.

The TBP28S42N is packaged in a 24-pin plastic dip (dual in-line package), which is a common package type used in electronic circuits. This makes it easy to integrate into existing designs or new projects. The device also features automatic write protection during power-up and power-down transitions, preventing data corruption during volatile power conditions. This write protection mechanism is essential for maintaining the integrity of the stored data.

In summary, the TBP28S42N from Texas Instruments is a robust and reliable nonvolatile SRAM solution that offers the speed of SRAM with the nonvolatility of ROM. It's an ideal memory component for applications that require fast access to data and preservation of data without power, such as industrial control systems, medical equipment, and critical data storage devices.
