Purpose

Eon Silicon Solution Inc. (hereinafter called “Eon”) is going to provide its products’ top marking on

ICs with < cFeon > from January 1st, 2009, and without any change of the part number and the

compositions of the ICs. Eon is still keeping the promise of quality for all the products with the

same as that of Eon delivered before. Please be advised with the change and appreciate your

kindly cooperation and fully support Eon’s product family.

Eon products’ Top Marking

cFeon Top Marking Example:

cFeon

Part Number: XXXX-XXX

Lot Number: XXXXX

Date Code:

XXXXX

Continuity of Specifications

There is no change to this data sheet as a result of offering the device as an Eon product. Any

changes that have been made are the result of normal data sheet improvement and are noted in

the document revision summary, where supported. Future routine revisions will occur when

appropriate, and changes will be noted in a revision summary.

Continuity of Ordering Part Numbers

Eon continues to support existing part numbers beginning with “Eon” and “cFeon” top marking. To

order these products, during the transition please specify “Eon top marking” or “cFeon top marking”

on your purchasing orders.

For More Information

Please contact your local sales office for additional information about Eon memory solutions.

This Data Sheet may be revised by subsequent versions

or modifications due to changes in technical specifications.

SIGNAL DESCRIPTION

Serial Data Input (DI)

The SPI Serial Data Input (DI) pin provides a means for instructions, addresses and data to be serially

written to (shifted into) the device. Data is latched on the rising edge of the Serial Clock (CLK) input pin.

Serial Data Output (DO)

The SPI Serial Data Output (DO) pin provides a means for data and status to be serially read from

(shifted out of) the device. Data is shifted out on the falling edge of the Serial Clock (CLK) input pin.

Serial Clock (CLK)

The SPI Serial Clock Input (CLK) pin provides the timing for serial input and output operations. ("See

SPI Mode")

Chip Select (CS#)

The SPI Chip Select (CS#) pin enables and disables device operation. When CS# is high the device is

deselected and the Serial Data Output (DO) pin is at high impedance. When deselected, the devices

power consumption will be at standby levels unless an internal erase, program or status register cycle is

in progress. When CS# is brought low the device will be selected, power consumption will increase to

active levels and instructions can be written to and data read from the device. After power-up, CS# must

transition from high to low before a new instruction will be accepted.

Hold (HOLD#)

The HOLD pin allows the device to be paused while it is actively selected. When HOLD is brought low,

while CS# is low, the DO pin will be at high impedance and signals on the DI and CLK pins will be

ignored (don’t care). The hold function can be useful when multiple devices are sharing the same SPI

signals.

Write Protect (WP#)

The Write Protect (WP#) pin can be used to prevent the Status Register from being written. Used in

conjunction with the Status Register’s Block Protect (BP0, BP1and BP2) bits and Status Register Protect

(SRP) bits, a portion or the entire memory array can be hardware protected.
