Input/Output Descriptions and Logic Symbols
Table identifies the input and output package connections provided on the device.
Symbol
Type
Description
A19-A0
Input
Address lines for S29CD-J and S29CL-J (A18-A0 for 16Mb and A19-A0 for 32Mb).
A9 supports 12V autoselect input.
DQ31-DQ0
I/O
Data input/output
CE#
Input
Chip Enable. This signal is asynchronous relative to CLK for the burst mode.
OE#
Input
Output Enable. This signal is asynchronous relative to CLK for the burst mode.
WE#
Input
Write Enable
VCC
Supply
Device Power Supply. This signal is asynchronous relative to CLK for the burst mode.
VIO
Input
VersatileI/O
TM
Input.
VSS
I/O
Ground
NC
No Connect
Not connected internally
RY/BY#
Output
Ready/Busy output and open drain which require a external pull up resistor.
When RY/BY# = V
OH
, the device is ready to accept read operations and commands.
When RY/BY# = V
OL
, the device is either executing an embedded algorithm or the
device is executing a hardware reset operation.
CLK
Input
Clock Input that can be tied to the system or microprocessor clock and provides the
fundamental timing and internal operating frequency.
AVD #
Input
Load Burst Address input. Indicates that the valid address is present on the address
inputs.
IND#
Output
End of burst indicator for finite bursts only. IND is low when the last word in the burst
sequence is at the data outputs.
WAIT#
Output
Provides data valid feedback only when the burst length is set to continuous.
WP#
Input
Write Protect Input. At V
IL
, disables program and erase functions in two outermost
sectors of the large bank.
ACC
Input
Acceleration input. At V
HH
, accelerates erasing and programming. When not used for
acceleration, ACC = V
SS
to V
CC
.
Hardware Reset.
RESET#
Input
