Address and Data Configuration
Input/Output Summary
Versatile I/O Feature
Ready/Busy# (RY/BY#)
Address and data are connected in parallel (ADP) via separate signal inputs and I/Os.
The maximum output voltage level driven by, and input levels acceptable to, the device are determined by the
V
same bus having interface signal levels different from the device core voltage.
RY/BY# is a dedicated, open drain output pin that indicates whether an Embedded Algorithm, Power-On
Reset (POR), or Hardware Reset is in progress or complete. The RY/BY# status is valid after the rising edge
of the final WE# pulse in a command sequence, when V

64 kword (128 kB) sector of the device. At V
internal pull up; When unconnected WP# is at V
Ready/Busy. Indicates whether an Embedded Algorithm is in progress or complete. At V
the device is actively engaged in an Embedded Algorithm such as erasing or programming.
At High-Z, the device is ready for read or a new command write - requires external pull-up
resistor to detect the High-Z state. Multiple devices may have their RY/BY# outputs tied
together to detect when all devices are ready.
Core power supply
Versatile IO power supply.
Power supplies ground
Not Connected internally. The pin/ball location may be used in Printed Circuit Board (PCB)
as part of a routing channel.
Reserved for Future Use. Not currently connected internally but the pin/ball location should
be left unconnected and unused by PCB routing channel for future compatibility. The pin/ball
may be used by a signal in the future.
Do Not Use. Reserved for use by Spansion. The pin/ball is connected internally. The input
has an internal pull down resistance to V
the PCB.
