Notes: Configuration of four 16-bit counters
Typical current at 5V, 25°C
ICC can be estimated for the ispLSI 1016E using the following equation:
ICC(mA) = 23 + (# of PTs * 0.52) + (# of nets * max freq * 0.004)
Where:
# 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)
The ICC estimate is based on typical conditions (VCC = 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 ICC is sensitive to operating conditions and the program in the device, the actual ICC should be verified.
