What are some of the improvements the BR93Hxx-2C series of microwire EEPROMs features over the BR93Hxxx-WC series?
- The BR93Hxx-WC reduces the lower limit of the operating supply voltage range from 2.7V to 2.5V, increases the data retention period from 40 years to 100 years, raises the SK frequency from 1.25MHz to 2MHz, and reduces the write cycle time from 10ms to 4ms.

What is an EEPROM?
- Short for Electrically Erasable Programmable ROM, EEPROMs are a type of non-volatile memory that allows data to be written to each address via electric signals. ROHM EEPROMs are capable of an industry best 1 million rewrites and retains data for up to 40 years. ROHM's unique double cell technology has been incorporated into the entire lineup, resulting in remarkably high reliability (zero accidental defects).
