GENERAL DESCRIPTION
Whenever VCC is applied to the module, it recharges the ML battery, powers the SRAM from the external power source, and allows the contents of the SRAM to be modified. Two versions of the DS2030 are available, which provide either a 5% or 10% power-monitoring trip point. The DS2030 also contains a power-supply monitor output, RST, which can be used as a CPU supervisor for a microprocessor. 27mm2 FEATURES
