• Description: In-system Programmable Superfast? High Density Pld
• Manufacturer: Lattice Semiconductor Corp.

Power consumption in the ispLSI 2032E device depends
on two primary factors: the speed at which the device is
operating and the number of Product Terms used.
Figure 3. Typical Device Power Consumption vs fmax
I
For 2032E-225 and -200: I CC = 4.5 + (# of PTs * 1.3) + (# of nets * Max freq * 0.0035)
For 2032E-180 and Slower: I CC = 4.5 + (# of PTs * 1.02) + (# of nets * Max freq * 0.0035)
Where:
The I
loads on average exists. These values are for estimates only. Since the value of I

Power Consumption
# of PTs = Number of Product Terms used in design
# of nets = Number of Signals used in device
Max freq = Highest Clock Frequency to the device (in MHz)
can be estimated for the ispLSI 2032E using the following equation:
