New 125°C operation-compatible I2C bus EEPROMs, BR24H-5AC series, targets applications that require data storage under harsh 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 BR24H-5AC series of 125°C operation-compatible EEPROMs is the first in the industry to achieve a writing time of 3.5 msec by implementing original data writing and reading circuit technology, reducing writing time by 30% compared to the 5 msec of conventional products. Additionally, 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.
Storing factory settings (e.g., onboard cameras) for ADAS
Ignition ON/OFF history
Cluster mileage display
Operating history (e.g., airbags), emergency data logging
Retaining settings for car navigation/audio
Data logging for industrial automation systems
…and other systems requiring high reliability data retention over a long period of time
