Description

A26–A0

Input

Address lines for GL02GS.

DQ15–DQ0

I/O

Data input/output.

CE#

Input

Chip Enable.

OE#

Input

Output Enable.

WE#

Input

Write Enable.

VCC

Supply

Device power supply.

VIO

Supply

Versatile IO input.

VSS

Supply

Ground.

RY/BY#

Output

Ready/Busy. Indicates whether an Embedded Algorithm is in progress or

complete. At VIL, the device is actively erasing or programming. At High Z, the

device is in ready.

RESET#

Input

Hardware Reset. LOW = device resets and returns to reading array data.

WP#

Input

Write Protect/Acceleration Input. At VIL, disables program and erase functions in

the outermost sectors. At VHH, accelerates programming; automatically places

device in unlock bypass mode. Should be at VIH for all other conditions.

NC

No Connect

Not Connected. No device internal signal is connected to the package connector

nor is there any future plan to use the connector for a signal. The connection may

safely be used for routing space for a signal on a printed circuit board (PCB).

DNU

Reserved

Do Not Use. A device internal signal may be connected to the package connector.

The connection may be used by Infineon for test or other purposes and is not

intended for connection to any host system signal. Any DNU signal related

function will be inactive when the signal is at VIL. The signal has an internal

pull-down resistor and may be left unconnected in the host system or may be tied

to VSS. Do not use these connections for PCB signal routing channels. Do not

connect any host system signal to these connections.

RFU

No Connect

Reserved for Future Use. No device internal signal is currently connected to the

package connector but there is potential future use for the connector for a signal.

It is recommended to not use RFU connectors for PCB routing channels so that the

PCB may take advantage of future enhanced features in compatible footprint

devices.
