DETERMINING ACTIVE CURRENT CONSUMPTION AND POWER DISSIPATION
The ICC(f) current for the graph in Figure 1 was taken while simultaneously reading and writing a FIFO on the IDT72V3684/72V3694/72V36104 with CLKA
andCLKBsettofS. Alldatainputsanddataoutputschangestateduringeachclockcycletoconsumethehighestsupplycurrent. Dataoutputsweredisconnected
to normalize the graph to a zero capacitance load. Once the capacitance load per data-output channel and the number of these device's inputs driven by TTL
HIGH levels are known, the power dissipation can be calculated with the equation below.
CALCULATING POWER DISSIPATION
With ICC(f) taken from Figure 1, the maximum power dissipation (PT) of these FIFOs may be calculated by:
PT = VCC x ICC(f) +
Σ(CL x VCC2 x fo)
N
where:
N
=
number of used outputs (36-bit (long word), 18-bit (word) or 9-bit (byte) bus size)
CL
=
output capacitance load
fo
=
switching frequency of an output
