EEPROM - ROHM -Macnica

Product Summary

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory that is used in computers and other electronic devices to store data that should be retained even when the power is turned off, such as setting information. ROHM's serial EEPROMs come in a wide variety of capacities, bus interfaces, and packages.

Product features

This time, we have released the next generation 0.13um process product BRxxxxxx 5/5A/5AC series. Also suitable for keyless entry and battery powered devices.

Achieves high-speed writing of 3.5ms, contributing to a 30% reduction in initial writing time
4 million rewritable times, contributing to the longevity of electronic equipment
1.8V low voltage operation, compatible with battery-powered applications

Adoption example

■ Preservation of factory settings for ADAS systems such as in-vehicle cameras
■ Cluster mileage display
■ Saving car navigation and car audio settings
■ Ignition on/off history
■ Operation history of airbags, emergency data log system
■ Data log system for FA equipment that is always energized
It is ideal for applications that require highly reliable data retention over long periods of time, such as
