Notes to Figure 17–1:
(1) Every device is fully utilized with 16-bit counters for power estimation.
(2) The MAX II and MAX IIG devices can operate up to 304 MHz.
(3) VCCINT = 3.3 V
(4) VCCINT = 2.5 V
(5) VCCINT = 1.8 V (MAX IIG)
(6) VCCINT = 1.8 V (MAX IIZ)
The power consumed in MAX II devices is dependent on the design. It is very
important to complete a power evaluation early in the design process to ensure that
the power dissipation by MAX II devices meets system requirements and
specifications.
This chapter discusses how to evaluate and manage MAX II power using the MAX II
PowerPlay Early Power Estimator spreadsheet, available at www.altera.com.
