The BR24H-5AC series of 125°C-compatible EEPROMs is the first in the industry to achieve a write time of 3.5 ms by implementing original data read/write circuitry technology, reducing write time by 30% compared to the 5 ms of conventional products. Furthermore, unlike standard products, which are only capable of 1 million write cycles, the BR24H-5AC series guarantees up to four million write cycles per data resistor, not only extending the lifespan of applications but also making it ideal for data registers that require frequent data rewrites.
In the automotive and industrial equipment sectors, safety and traceability requirements necessitate storing the operational history in non-volatile memory within the system. In this context, EEPROMs are often preferred over other types of non-volatile memory, such as flash memory, in applications requiring high reliability, for example, in on-board cameras, airbags, and industrial automation systems and servers, due to their ability to reliably write and store data under harsh conditions.
As a leading semiconductor manufacturer with over 20 years of experience developing EEPROMs, ROHM offers high-quality products that have been well-received in the automotive, industrial equipment, and consumer goods markets, leveraging its proprietary high-reliability memory cell technology. This latest series of I²C bus EEPROMs is designed to reduce pre-shipment processing time in industrial and automotive applications.
ROHM is committed to contributing to reduced processing time during factory shipment along with greater application reliability by developing SPI bus compatible products while continuing to expand its product range by capacity.
