... Additionally, the DS1330W has dedicated circuitry for monitoring the status of V and the status of the internal lithium battery. DS1330W devices in the PowerCap Module package CC are directly surface mountable and are normally paired with a DS9034PC PowerCap to form a complete Nonvolatile SRAM module ...

... On power-up, RST during power-on transients and to allow t BATTERY MONITORING The DS1330W automatically performs periodic battery voltage monitoring on a 24-hour time interval. Such monitoring begins within t occurs. After each 24-hour period has elapsed, the battery is connected to an internal 1MΩ test resistor for 1 second ...

... The 34-pin PowerCap Module integrates SRAM memory and nonvolatile control into a module base along with contacts for connection to the lithium battery in the DS9034PC PowerCap. The PowerCap Module package design allows a DS1330W device to be surface mounted without subjecting its lithium backup battery to destructive high-temperature reflow soldering. After a DS1330W module base is reflow soldered, a DS9034PC is snapped on top of the base to form a complete Nonvolatile SRAM module ...
