Choice List [Parts Count also]
|
Required only for the Memory subcategory.
The type of device. Many different choices are available including DRAM, RAM, SRAM, and more.
|
|
Technology Type
|
Choice List [Parts Count also]
|
Not required for the Linear subcategory. For the Parts Count model only, not required for the EEPROM subcategory.
The technology type of the device. The choices vary by subcategory.
|
|
CMOS
|
Checkbox
|
Not required for the following subcategories: EEPROM, Linear, and Memory. For the remaining subcategories, required only when MOS is the technology type.
When selected, the MOS technology is used.
|
|
Quality Level
|
Choice List [Parts Count also]
|
The appropriate quality screening level of the device. Accepted quality levels and values for general integrated circuits follow.
• A2 = 0.10
• A3 = 0.14
• A4 = 0.25
• B1 = 0.50
• B2 = 1.00
• C1 = 4.00
|
|
# of Bits
|
Integer [Parts Count also]
|
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 [Parts Count also]
|
Required only for the following subcategories: EEPROM and Memory.
The units for the # of Bits value. Choices are:
• b (bits)
• kb (1024 bits)
• Mb (1,048,576 bits)
• Gb (1,073,741,824 bits)
You can enter the bits several ways. For a 1 kilobyte memory chip for example, you can type 1 for # of Bits and select kb for Units. Or, you can type 1024 for # of Bits and select b for Units.
|
|
Pins
|
Integer
|
The number of active pins in the package.
|
|
# of Gates
|
Integer
|
Not required for the Microprocessor subcategory.
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. For the purposes of a 299B prediction, 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 device transistor count to determine gate count using the following equations:
• Bipolar: Gates = # of Transistors / 3
• CMOS: Gates = Gates = # of Transistors / 4
• All other MOS, except CMOS: Gates = # of Transistors / 3
|
|
Word Size
|
Choice List [Parts Count also]
|
Required only for the Microprocessor subcategory.
The length of the data word used by the microprocessor.
|
|
Programming Cycles
|
Integer
|
Required only for the EEPROM subcategory.
The total number of programming cycles over the life of the device.
|
|

• Hermetic: DIPs, PGA, SMT
• DIP, Glass Seal
• Flatpack
• Can
• Nonhermetic: DIPs, PGA, SMT
|
|
