Main Memory
There is 1.5 MByte SRAM in total which is connected to AHB of the Application Processor.
The SRAM is made up of 128 KByte Logic Tiles. Each of them has the AHB I/F individually.
In addition, the Logic Tile is the unit for the SRAM access protection function.
You can use protection feature that keeps masters with specific Master ID from accessing specific SRAM Logic
Tiles. The protection feature can be controlled via buses.
Power domain of Main Memory is PWD_APP. When PWD_APP is turned off, this memory cannot be used.
Power on/off can be controlled suitably by power switch inside SRAM for each 128 KByte Logic Tile. There are
two operation modes for SRAM power-off; they can be set by system control registers.
Retention mode
A mode in which only the power supply of SRAM memory array is ON, and the power supply of the
peripheral circuitry is turned OFF. In Retention mode, the SRAM cannot be accessed, but the data
within the SRAM is retained. By turning on (ON mode) the power supply of peripheral circuitry of the
SRAM once again, the data within the SRAM can be accessed. Retention mode enables reduction of the
leakage power and recovery of high speed of peripheral circuitry for SRAMs that are temporarily not
used.
Shutdown mode
A mode that turns OFF both the power supply of the SRAM memory array and peripheral circuitry.
This mode consumes less power than the Retention mode, but the data in the SRAM is not retained.
