= 10 μA x 0.9 + (0.8 x 0.8 mA/MHz x 2 MHz + 5.0 mA) x 0.1
= 9.0 μA + (1.28 mA + 5.0 mA) x 0.1
= 637 μA, based on the system operating in standby 90% of the time
Once you have read the “Power Management” section, you should be able to calculate
power. The following is a sample power calculation:
NOTES:
1. Calculation is based on the assumption that Iout = 0 mA (no I/O pin loading).
2. I
CC
(DC) is zero for all ZPSD devices operating in non-turbo mode.
3. 10 product terms: 8 for EPROM, 1 for CSIOPORT, 1 for CS8
4. The 5% I/O access in the conditions section is when the MCU accesses CSIOPORT space.
5. Standby Mode can also be achieved without using the CSI pin. The ZPSD device will automatically
go into Standby while no inputs are changing on any pin, and Turbo Mode is disabled.
