• Manufacturer Part Number: ng80960kb-25
• Description: Embedded 32-bit Microprocessor With Integrated Floating-point Unit
• Manufacturer: Intel Corporation

1. Clock rise and fall times are not tested.
2. A float condition occurs when the maximum output current becomes less than I
3. LAD31:0, BADAC, HOLD, LOCK and READY are synchronous inputs. IAC/INT
