Functional Description
2.1
Power-Up and Initialization
The power-up and initialization sequence guarantees that the device is preconditioned to the user’s specific
needs. Like conventional DRAMs, the CellularRAM must be powered up and initialized in a predefined manner.
V
DD
and
V
DDQ
must be applied at the same time to the specified voltage while the input signals are held in
“DESELECT” state (CS1 = High).
After power on, an initial pause of 150
μ
s is required prior to the control register access or normal operation. Failure
to follow these steps may lead to unpredictable start-up modes.
