ST’s ZEROPOWER products integrate low-power SRAMs with a power-fail control circuit and a long-life lithium battery.

The power-fail circuit monitors the external power supply voltage. If this falls below a specific threshold, it automatically write-protects the SRAM and switches the standby power supply to the internal lithium battery.

The advantage is long-term data retention with fast read/write times and unlimited read/write cycles of standard SRAMs.

To ease your design with ZEROPOWER products, ST offers the ZEROPOWER? battery life calculation simulator. Select the CAPHAT? or SNAPHAT? package option to start calculating the data retention lifetime vs. temperature.
