Power Management
Three low-power modes are available:
The SDRAM Controller activates one low-power mode as soon as the SDRAM device is not
selected. It is possible to delay the entry in self-refresh and power-down mode after the last
access by programming a timeout value in the Low Power Register.
• Self-refresh Mode: The SDRAM executes its own Auto-refresh cycle without control of the
• Power-down Mode: Auto-refresh cycles are controlled by the SDRAM Controller. Between
• Deep Power-down Mode: (Only available with Mobile SDRAM) The SDRAM contents are
SDRAM Controller. Current drained by the SDRAM is very low.
auto-refresh cycles, the SDRAM is in power-down. Current drained in Power-down mode is
higher than in Self-refresh Mode.
lost, but the SDRAM does not drain any current.
