S29CD-J & S29CL-J Flash Family
Address lines for S29CD-J and S29CL-J (A18-A0 for 16Mb and A19-A0 for 32Mb).
A9 supports 12V autoselect input.
Data input/output
Chip Enable. This signal is asynchronous relative to CLK for the burst mode.
Output Enable. This signal is asynchronous relative to CLK for the burst mode.
Write Enable
Device Power Supply. This signal is asynchronous relative to CLK for the burst mode.
VersatileI/O
Ground
Not connected internally
Ready/Busy output and open drain which require a external pull up resistor.
When RY/BY# = V
When RY/BY# = V
device is executing a hardware reset operation.
Clock Input that can be tied to the system or microprocessor clock and provides the
fundamental timing and internal operating frequency.
Load Burst Address input. Indicates that the valid address is present on the address
inputs.
End of burst indicator for finite bursts only. IND is low when the last word in the burst
sequence is at the data outputs.
Provides data valid feedback only when the burst length is set to continuous.
Write Protect Input. At V
sectors of the large bank.
Acceleration input. At V
acceleration, ACC = V
