(1) All timing parameters are described in Tables 22 through 29 in this data sheet.
(2) These parameters are specified by characterization.
(3) This parameter is measured without the use of the ClockLock or ClockBoost circuits.
(4) This parameter is measured with the use of the ClockLock or ClockBoost circuits.
The supply power (P) for ACEX 1K devices can be calculated with the
following equation:
Power
Consumption
P = PINT + PIO = (ICCSTANDBY + ICCACTIVE) × VCC + PIO
The ICCACTIVE value depends on the switching frequency and the
application logic. This value is calculated based on the amount of current
that each LE typically consumes. The PIO value, which depends on the
device output load characteristics and switching frequency, can be
calculated using the guidelines given in Application Note 74 (Evaluating
Power for Altera Devices).

Compared to the rest of the device, the embedded array
consumes a negligible amount of power. Therefore, the
embedded array can be ignored when calculating supply
current.
