The B3 flash memory device also provides Automatic Power Savings (APS), which minimizes
system current drain and allows for very low power designs. This mode is entered following the
completion of a read cycle (approximately 300 ns later).
The RP# pin provides additional protection against unwanted command writes that might occur
during system reset and power-up/down sequences due to invalid system bus conditions (see

The Command User Interface (CUI) is the interface between the microprocessor or
microcontroller and the internal operation of the flash memory.
The internal Write State Machine (WSM) automatically executes the algorithms and timings
necessary for Program and Erase operations (including verification), which unburdens the
microprocessor or microcontroller.
To indicate the status of the WSM, the Status Register signifies block erase or word program
completion and status.
