Synchronous PSRAM AC Characteristics
The figures and tables below shows the PSRAM AC characteristics. All timing
parameters are measured with the default output drive strength (half drive strength).
8.1
PSRAM Asynchronous Read
Notes:
1.
Timing parameters are at the default output drive strength (half drive strength).
2.
tCSL max limit applies during asynchronous reads when page mode is enabled.
3.
Applies to ADV# controlled Asynchronous Read operations.
4.
Applies when control signals (ADV#, CS#, UB#/LB#) are active.
5.
When operating the PSRAM as an ADMux I/O interface, Page-Mode operation is not available.
