XC9500 concurrently

Available in 44-pin PLCC, 84-pin PLCC, 100-pin PQFP, and 100-pin TQFP packages

Power Management

Power dissipation can be reduced in the XC9572 by configuring macrocells to standard or low-power modes of operation. Unused macrocells are turned off to minimize power dissipation.

Operating current for each design can be approximated for specific operating conditions using the following equation:

ICC (mA) = MCHP (1.7) + MCLP (0.9) + MC (0.006 mA/MHz) f

Where:

MCHP = Macrocells in high-performance mode

MCLP = Macrocells in low-power mode

MC = Total number of macrocells used f = Clock frequency (MHz)

Figure 1 shows a typical calculation for the XC9572 device.
