EEPROMs with I²C deliver robust performance in harsh environments

With its BR24S series of enhanced EEPROMs, Rohm has achieved a non-volatile memory that performs reliably in harsh environments including conditions where the power source is unstable.

Among the enhancements Rohm has delivered in the BR24S series, is double-cell technology which minimises random bit failures. In addition, double-reset protection further reduces data failures. Other enhancements include write-mistake prevention and support for page-write mode, as well as auto-erase and auto-end functions at data rewrite. In addition, a sub-5ms write time assures versatile highspeed operation.

Further benefits of Rohm’s new EEPROMs include low current draw of 0.5mA or 0.l2mA during all-write or all-read operations. Stand-by power is also low, at 0.1µA, allowing engineers to easily meet low-power codes coming into effect world-wide. The devices can operate from a supply voltage in the range 1.7V to 5.5V.

The operating temperature range is -40°C to 85°C, and extended-temperature versions are available up to 125°C.

The BR24S series is available in a variety of compact packages, including SOP-8, in densities of 16kbyte, 32kbyte, 64kbyte, 128kbyte and 256kbyte.
