Notes to tables:
(1)
These values are specified under the MAX 9000 device recommended operating conditions, shown in
Table 12 on(2)
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 tLPA parameter must be added to the tLOCAL parameter for macrocells running in low-power mode.
(6)
The tROW , tCOL, and tIOC 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 (fMAX) for MAX 9000 devices can
be calculated with the following equation:
P = PINT + PIO = ICCINT × VCC + PIO
The PIO value, which depends on the device output load characteristics
and switching frequency, can be calculated using the guidelines given in
depends on the switching frequency and the application logic.
The ICCINT value is calculated with the following equation:
ICCINT
= (A
× MC
TON) + [B × (MCDEV – MCTON)] + (C × MCUSED
× f
MAX × togLC)
