• Deep power-down mode

If the RMODE bit in the SDCR is set to 1 while the DEEP and RFSH bits in the SDCR are set to

1, the low-power SDRAM enters the deep power-down mode. If the RMODE bit is cleared to 0,

the CKE signal is pulled high to cancel the deep power-down mode. Before executing an access

after returning from the deep power-down mode, the power-up sequence must be re-executed.

The low-power SDRAM supports the deep power-down mode as a low-power consumption

mode. In the partial self-refresh function, self-refresh is performed on a specific area. In the

deep power-down mode, self-refresh will not be performed on any memory area. This mode is

effective in systems where all of the system memory areas are used as work areas.

Notes: 1. Address pin to be connected to pin A10 of SDRAM.

2. The waveform for DACKn is when active low is specified.
