New faster operation compatible EEPROMs extend service life

20-01-2021 | ROHM Semiconductor | Semiconductors

ROHM’s new 125C operation compatible I²C bus EEPROMs, BR24H-5AC series is aimed at applications that need data storage under severe environments, such as factory settings for onboard cameras and sensors, airbag operating history, and data logging for always-on operating industrial automation systems and servers.


The series is claimed to be the first to deliver a writing time of 3.5ms by implementing original data writing and reading circuit technology, lessening writing time by 30% compared to the 5ms of conventional products. Furthermore, in contrast to standard products capable of only one million rewrites, the new series guarantees up to four million writing cycles by data endurance, which not only increases application service life, but is excellent for data loggings needing frequent data rewrites.


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