Notes to tables:
(1) These values are specified under the MAX 9000 device recommended operating conditions, shown in Table 15 on
page 27.
(2) See Application Note 77 (Understanding MAX 9000 Timing) for more information on test conditions for t_PD1 and t_PD2
delays.
(3) This parameter is a guideline that is sample-tested only. It is based on extensive device characterization. This
parameter applies for both global and array clocking as well as both macrocell and I/O cell registers.
(4) Measured with a 16-bit loadable, enabled, up/down counter programmed in each LAB.
(5) The t_LPA parameter must be added to the t_LOCAL parameter for macrocells running in low-power mode.
(6) The t_{ROW ,} t_COL, and t_IOC delays are worst-case values for typical applications. Post-compilation timing simulation
or timing analysis is required to determine actual worst-case performance.
Power
Consumption
The supply power (P) versus frequency (f_MAX) for MAX 9000 devices can
be calculated with the following equation:
P = P_INT + P_IO = I_CCINT × V_CC + P_IO
The P_IO 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). The I_CCINT value
depends on the switching frequency and the application logic.
The I_CCINT value is calculated with the following equation:
I_CCINT
= (A × MC_TON) + [B × (MC_DEV – MC_TON)] + (C × MC_USED
× f_MAX × tog_LC)
