Operating Modes And Current Drain - Hitachi H8/300L Series Manual

2. Operating Modes and Current Drain

The table below shows the relationship between the operating modes and the IC current drain.
The H8/300L Series microcomputers allow precise program control (using the SLEEP
instruction) of power dissipation to match the power saving conditions required by the
application. Thus these microcomputers can be extremely effective when used in portable
equipment requiring battery operation.
