Faster 125°C operation compatible EEPROMs extend service life

ROHM’s has introduced 125°C operation compatible I²C bus EEPROMs. The BR24H-5AC series targets applications that require data storage under harsh environments.

The BR24H-5AC series of 125°C operation compatible EEPROMs is the first in the industry to achieve a writing time of 3.5ms by implementing original data writing and reading circuit technology, reducing writing time by 30% compared to the 5ms of conventional products. In contrast to standard products capable of just 1 million rewrites, the BR24H-5AC series guarantees up to four million writing cycles by data endurance, which not only extends application service life, but is ideal for data loggings requiring frequent data rewrites.

In the automotive and industrial equipment sector, safety and traceability requirements make it necessary to store the operating history in non-volatile memory in the system. Among these, EEPROMs are typically adopted over other types of non-volatile memory such as flash memory in applications that require high reliability, including onboard cameras, airbags, industrial automation systems and servers, due to their ability to reliably write and store data under harsh conditions.

This latest series of I²C bus EEPROMs is designed to reduce process time before factory shipment in automotive and industrial equipment applications.
