A universal interface circuit and an associated method are provided that can supply a computer logic circuit, such as the components mounted upon an adapter card, with first and second inputs having first and second predetermined voltage levels, respectively, based upon power drawn from both first and second supply voltages. The interface circuit typically includes a first power supply circuit for providing the first input having the first predetermined voltage level in response to the first supply voltage. Additionally, the interface surface includes a regulator for generating an output having the second predetermined voltage level in response to the first supply voltage. The interface circuit further includes a second power supply circuit for providing an output that also has the second predetermined voltage level, albeit in response to the second supply voltage. In order to divide the anticipated load between the first and second supply voltages, the regulator and the second power supply circuit cooperate to provide the second input having the second predetermined voltage level in instances in which the second supply voltage is present. The interface circuit provides for the universal operation of the computer logic circuit, however, in that the regulator will provide the second input having the second predetermined voltage level in a manner independent of the second power supply circuit in instances in which the second supply voltage is unavailable.

Intelligent transportable data storage component module for a data processing system and a method for charging a battery for a data storage component in an intelligent transportable data storage component module. The intelligent transportable data storage component module has a data storage component and an intelligent battery backup for providing power to the data storage component. The intelligent battery backup, for example, a battery backup falling within Smart Battery Specifications, has a battery and a battery charger that function as a unit to monitor and charge the battery independent of the host processor and firmware of the data processing system and independent of characteristics of the battery.

A microprocessor based system automatically detects the occurrence of certain conditions in the microprocessor. The conditions may include a determination of data corruption in the microprocessor. If a determination is made that data is corrupted, the microprocessor may be reloaded from a non-volatile memory. During a reload, a microcontroller controls the microprocessor. The non-volatile memory may be a flash memory or non-volatile random access memory.

Automode select

A method and circuit allows flexible control for termination of a signal line. The mode of operation of the circuit may be set manually or automatically. A software controller provides software control of the signal line. A bus terminator is tied to the signal line. A feedback line from the bus terminator permits monitoring the logic level on the signal line by the software controller. The modes permit software control of the termination or operator setting of the termination by grounding of the signal line or pulling up the signal line to the power line.

Systems and methods for transferring data. A circuit transfers information between two buses using different signal voltage levels and multiplexes signals applied to the second bus over multiple devices coupled thereto. The data on a first data bus is transferred at a first voltage level and the data on a second data bus is transferred at a second voltage level. For example, the first data bus may transfer data at 3.3V and the second data bus may transfer data at 5V. A logic device (e.g., a CPLD) is connected between the first and the second data buses for transferring the data between the first and second voltage levels. The logic device is also configured for multiplexing the data with the second voltage level between first and second devices (e.g., one or more LEDs and/or NVSRAMs) connected to the second data bus.

Method and apparatus for transferring data between data buses

A transportable memory apparatus including cache memory and a backup battery is provided that is capable of being removed from a first computer system and installed within a second computer system. The transportable memory apparatus includes a control bus that provides appropriate signals such that the presence and status of the transportable memory apparatus can be detected in order to permit the computer system that includes the transportable memory apparatus to be appropriately initialized. As such, methods for initializing a computer system that may include a transportable memory apparatus are also provided.
