PSRAM Operations
Power-Up Sequence and Initialization
The PSRAM functionality and reliability are independent of the power-up sequence and slew rate
of the core P-V
reliability are also independent of the power-down sequence and slew rate of the core P-V
The following power-up sequence and register setting should be used before starting normal
operation. The PSRAM power-up sequence is represented in
application, make P-Mode high after fixing P-Mode to a low level for a period of t
high before making P-Mode high. P-CS# and P-Mode are fixed to a high level for period of t
Once the power-up sequence is complete, be sure to set the register, before starting any normal
operation. The register is set by a five-cycle operation. The process involves first performing a
dummy read immediately followed by two continuous reads of the address 0x1FFFFF then
successively writing two specific data. See the flowchart in
of setting the register. Note that P-CS# must be toggling to high for a minimum of 10 ns between
each read or write.
