BR24H-5AC Series of High-Temperature Operating EEPROMS for Extended Service Life in Harsh Industrial and Automotive Applications
The BR24H-5AC series of I2C EEPROMs introduced by ROHM focus on applications that require data storage under harsh environments like factory settings for onboard cameras and sensors, airbag operating history, and data logging for always-on operating industrial automation systems and servers. By implementing original data writing and reading circuit technology the 125°C operations compatible BR24H-5AC achieves a writing time of 3.5ms which is 30% less compared to the 5ms writing time of conventional products.
The four million writing cycles by data endurance of the device helps in extended application service life and makes it ideal for data logging that requires frequent data rewrites. The EEPROMs are the most suitable type of non-volatile memory for 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. The AEC-Q100 qualified device is suitable for 3V and 5V applications, they can also be used for low voltage operations such as 1.8V battery applications like keyless entry.
The BR24H-5AC series of I2C EEPROMs is offered in a variety of common surface-mount packages, hence they can be used in a variety of applications such as 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.
