Choice List
|
The type of device. Choices vary by subcategory.
|
|
Voltage
|
Choice List
|
Required only for the Linear subcategory.
The type of voltage of the device. Choices are:
• Low Voltage
• High Voltage
|
|
Quality Level
|
Choice List
|
The quality screening level used in the manufacturing of the device. For more information, see HRD5 Quality Levels.
|
|
# of Bits
|
Integer
|
Required only for the following subcategories: EEPROM and Memory.
The number of bits in the memory device. This parameter is used in conjunction with Units to enter the memory device bits.
|
|
Units
|
Choice List
|
Required only for the following subcategories: EEPROM and Memory.
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.

Package Type
|
Choice List
|
Indicates how the device is packaged. Choices are:
• Fragile
• Non-Fragile
|
|
Mounting Method
|
Choice List
|
Indicates how the device is mounted on the printed circuit board. Choices are:
• Through Hole
• Surface Mount
|
|
Year Produced
|
Integer
|
The four-digit year in which the device was manufactured (such as 1998 or 2004).
|
|
# of Gates
|
Integer
|
Required only for the following subcategories: Logic, CGA or ASIC; and Microprocessor.
The number of active gates in the package. You can determine the gate count from the logic diagram. A J-K or R-S flip flop is equivalent to 6 gates when used as part of an LSI circuit. A gate is considered to be any one of the following functions: AND, OR, exclusive OR, NAND, NOR, and inverter. When a logic diagram is not available, use a device transistor count to determine gate count using the following equations:
• For MOS, including CMOS: Gates = # of Transistors / 4
• For Bipolar, VLSI: Gates = Gates = # of Transistors / 5
• For BICMOS, Bipolar and MOS (VLSI): Gates = # of Transistors / 4
|
|
# of Gates/Macros
|
Integer
|
Required only for the PAL, PLA subcategory.
The number of active gates or macros in the package. The information above can be used to determine the gate count from the logic diagram.
|
|
# of Transistors
|
Integer
|
Required only for the following subcategories: Custom and Linear.
The number of active transistors in the package. You can determine the transistor count from the logic diagram.
