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.
