Choice List [Parts Count also]
|
The type of device. The choices are:
• Nonseed Bubble Generator
• Seed Bubble Generator
|
|
Chips/Package
|
Choice List [Parts Count also]
|
The number of bubble chips in the package.
|
|
Dissipative Elements
|
Choice List [Parts Count also]
|
The total number of dissipative control elements. This includes generate, replicate, and detector elements.
|
|
Quality Level
|
Choice List
|
The quality screening level used in the manufacturing of the device. Choices are:
• S
• B
• B-1
• Commercial
If the device is screened to custom or intermediate programs, you can enter a Pi Q value directly in Pi Q Value. For more information, see MIL-HBDK-217 Quality Levels
|
|
# of Bits
|
Integer [Parts Count also]
|
The number of bits in the device. This parameter is used in conjunction with Units to enter the memory device bits.
|
|
Units
|
Choice List [Parts Count also]
|
The units for the value in # of Bits. Choices are:
• b (bits)
• Kb (1024 bits)
• Mb (1,048,576 bits)
• Gb (1,073,741,824 bits)
The default is Kb. However, you can enter the unit in many ways. For example, for a 1-kilobit memory chip, you can enter a 1 for # of Bits and select Kb for Units, or you can enter 1024 for # of Bits and select b for Units.
|
|
Pins
|
Integer [Parts Count also]
|
The number of active pins in the package.
|
|
Years in Production
|
Choice List [Parts Count also]
|
The number of years the device has been in production. Choices are:
• >=2.0
• 1.5
• 1.0
• 0.5
• <=0.1
|
|
Reads/Writes
|
Integer [Parts Count also]
|
The ratio of the number of memory reads for every memory write. If this ratio is less than 1, enter 0.
|
|
Average Data Rate
|
Real [Parts Count also]
|
The average data rate over the time that power is applied to the equipment using the device.
|
|
Maximum Data Rate
|
Real [Parts Count also]
|
The manufacturer's maximum rated data rate.
|
|
Duty Cycle
|
Real [Parts Count also]
|
The percentage of time that the device is in an operational (on) state. Generally, this field is left at #.# so that the duty cycle is calculated as follows:
Duty Cycle Ratio = Average Data Rate / Maximum Data Rate * 100
If you enter a value for this parameter, this value is used in place of a calculated duty cycle.
