The PSRAM block provides a memory mapped region that may be used by the instantiating system and other masters in the system to store various types of information. This region behaves as a standard byte-accessible static RAM. The PSRAM is a vbusp bus interface connected to a RAM. It has no control registers, and maps the bus interface address, control, and data signals to the address, control, and data of the RAM. The VBUSP protocol is a single-issue (i.e. pended), strongly ordered protocol that emphasizes simplicity over the highest possible performance.
MCU_PSRAM0_RAM, of size 512 Bytes, will survive any reset (MCU_PORz, PORz or Warm Reset) as long as the MCU domain is powered through the reset.
