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

No Connect

Not connected internally

RY/BY#

Output

Ready/Busy output and open drain which require a external pull up resistor.

When RY/BY# = VOH, the device is ready to accept read operations and commands.

When RY/BY# = VOL, 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 VIL, disables program and erase functions in two outermost

sectors of the large bank.

ACC

Input

Acceleration input. At VHH, accelerates erasing and programming. When not used for

acceleration, ACC = VSS to VCC.

RESET#

Input

Hardware Reset.
