• Manufacturer Part Number: ISPLSI1016E
• Description: In-System Programmable High Density PLD
• Manufacturer: Lattice Semiconductor

I CC can be estimated for the ispLSI 1016E using the following equation:
I CC (mA) = 23 + (# of PTs * 0.52) + (# of nets * max freq * 0.004)
Where:
The I CC estimate is based on typical conditions (V CC = 5.0V, room temperature) and an assumption of four GLB loads
on average exists and the device is filled with four 16-bit counters. These values are for estimates only. Since the
value of I CC is sensitive to operating conditions and the program in the device, the actual I CC should be verified.
Power consumption in the ispLSI 1016E device depends
on two primary factors: the speed at which the device is
operating and the number of Product Terms used.
