x % time CSI is low
= 10 μA x 0.9 + (0.8 x 0.8 mA/MHz x 2 MHz + 0.15 x 1.4 mA/MHz x 2 MHz
+ 5.0 mA) x 0.1
= 9.0 μA + (1.28 mA + 0.42 mA + 5.0 mA) x 0.1
= 679 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:

Calculating
Power
NOTES
: 1. Calculation is based on the assumption that I
OUT
= 0 mA (no I/O pin loading)
2. I
CC
(DC) is zero for all ZPSD devices operating in non-turbo mode.
3. 13 product terms: 8 for EPROM, 3 for Chip Selects, 1 for SRAM, 1 for CSIOPORT.
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.
