Important information | "Serial EEPROM Selection Guide Ver.2.0" is here!

EEPROM stands for Electrically Erasable Programable ROM (electrically erasable programmable non-volatile memory), which is installed on a circuit board and inputs electrical signals, and can rewrite the data at each address. ROHM's EEPROM can be rewritten 1 million times, the highest level in the industry, and data can be saved for 40 years. The memory cells of all models in the series use ROHM's original W-CELL (double cell) technology, which is proud of its unparalleled high reliability (zero data "random failures").

In the field of automotive and industrial equipment, due to safety and traceability management requirements, system operating data needs to be recorded in non-volatile memory in the system. Among them, compared with non-volatile FLASH memory, non-volatile EEPROM memory can save and write data more stably in harsh environments. Therefore, it is often used in vehicle-mounted cameras and security systems in the field of automotive and industrial equipment. In applications that require relatively high reliability, such as air bags, FA equipment and servers.

Universal EEPROM

ROHM's universal serial EEPROM has various capacities and packages such as SPI, I2C, Micro Wire, Plug & Play, etc. ROHM's proud 3.5ms high-speed writing product BR24G-5A (I2C) not only helps improve the production efficiency of application products, but also helps extend the service life of application products by achieving 4 million erasing and writing times. . In addition, the ECC function is built-in to correct errors caused by unexpected failures of the memory, helping to improve the reliability of written data. It is also suitable for battery-operated devices because it saves energy and operates at low voltage.

Automotive EEPROM

ROHM's automotive EEPROM has been widely used in airbags, car navigation systems, rearview systems, power windows, ECU, ABS and other fields that require high reliability. In addition, because it saves energy and operates at low voltage, it is also suitable for keyless entry systems and battery-operated equipment. The operating temperature range is as wide as -40~125℃, and it complies with the automotive electronics reliability standard AEC-Q100 to meet strict requirements.
