Power Consumption
X23A-G-006-03
Issue Date: 01/02/05
1.1 Conditions
Table 1-1: “S1D13505 Total Power Consumption” below gives an example of a specific
environment and its effects on power consumption.
environment and its effects on power consumption.
Note
1. Conditions for Software SUSPEND:
• CPU interface active (signals toggling)
• CLKI active
• Self-Refresh DRAM
2. Conditions for Hardware SUSPEND:
• CPU interface inactive (high impedance)
• CLKI stopped
• Self-Refresh DRAM
2 Summary
The system design variables in Section 1, “S1D13505 Power Consumption” and in Table 1-1:
“S1D13505 Total Power Consumption” show that S1D13505 power consumption depends on the
specific implementation. Active Mode power consumption depends on the desired CPU perfor-
mance and LCD frame-rate, whereas Power Save Mode consumption depends on the CPU Interface
and Input Clock state.
“S1D13505 Total Power Consumption” show that S1D13505 power consumption depends on the
specific implementation. Active Mode power consumption depends on the desired CPU perfor-
mance and LCD frame-rate, whereas Power Save Mode consumption depends on the CPU Interface
and Input Clock state.
In a typical design environment, the S1D13505 can be configured to be an extremely power-efficient
LCD Controller with high performance and flexibility.
