General Description

The S29WS128J/S29WS064J is a 128/64 Mbit, 1.8 Volt-only, simultaneous Read/Write,

Burst Mode Flash memory device, organized as 8,388,608/4,194,304 words of 16 bits

each. This device uses a single V

of 1.65 to 1.95 V to read, program, and erase the

memory array. A 12.0-volt V

on ACC may be used for faster program performance if

desired. The device can also be programmed in standard EPROM programmers.

At 80 MHz, the device provides a burst access of 9.1 ns at 30 pF with a latency of 46 ns

at 30 pF. At 66 MHz, the device provides a burst access of 11.2 ns at 30 pF with a latency

of 56 ns at 30 pF. The device operates within the industrial temperature range of -40°C to

+85°C and the wireless temperature range of -25°C to +85°C. The device is offered in

Various FBGA packages.

The Simultaneous Read/Write architecture provides

simultaneous operation

by divid-

ing the memory space into four banks. The device can improve overall system perfor-

mance by allowing a host system to program or erase in one bank, then immediately and

simultaneously read from another bank, with zero latency. This releases the system from

waiting for the completion of program or erase operations.

The device is divided as shown in the following table:

The device uses Chip Enable (CE#), Write Enable (WE#), Address Valid (AVD#) and Out-

put Enable (OE#) to control asynchronous read and write operations. For burst opera-

implementation allows easy interface with minimal glue logic to a wide range of micropro-

cessors/microcontrollers for high performance read operations.

The burst read mode feature gives system designers flexibility in the interface to the de-

vice. The user can preset the burst length and wrap through the same memory space, or

read the flash array in continuous mode.

The clock polarity feature provides system designers a choice of active clock edges, either

rising or falling. The active clock edge initiates burst accesses and determines when data

will be output.

The device is entirely command set compatible with the

JEDEC 42.4 single-power-

supply Flash standard.

Commands are written to the command register using standard

microprocessor write timing. Register contents serve as inputs to an internal state-ma-

chine that controls the erase and programming circuitry. Write cycles also internally latch

addresses and data needed for the programming and erase operations. Reading data out

of the device is similar to reading from other Flash or EPROM devices.

The

Erase Suspend/Erase Resume

feature enables the user to put erase or program

on hold for any period of time to read data from, or program data to, any sector that is

not selected for erasure. True background erase can thus be achieved. If a read is needed

from the SecSi™ Sector area (One Time Program area) after an erase suspend, then the

user must use the proper command sequence to enter and exit this region. Program sus-

pend is also offered.

The

hardware RESET# pin

terminates any operation in progress and resets the internal

state machine to reading array data. The RESET# pin may be tied to the system reset cir-

cuitry. A system reset would thus also reset the device, enabling the system microproces-

sor to read boot-up firmware from the Flash memory device.

The host system can detect whether a program or erase operation is complete by using

the device status bit DQ7 (Data# Polling) and DQ6/DQ2 (toggle bits). After a program or

erase cycle has been completed, the device automatically returns to reading array data.

The

sector erase architecture

allows memory sectors to be erased and reprogrammed

without affecting the data contents of other sectors. The device is fully erased when

shipped from the factory.

Hardware data protection

measures include a low V

detector that automatically in-

hibits write operations during power transitions. The device also offers two types of data

protection at the sector level. When at V

WP#

locks the four outermost boot sectors.

The device offers two power-saving features. When addresses have been stable for a

specified amount of time, the device enters the

automatic sleep mode.

The system can

also place the device into the

standby mode.

Power consumption is greatly reduced in

both modes.

Spansion™ Flash memory products combine years of Flash memory manufacturing expe-

rience to produce the highest levels of quality, reliability and cost effectiveness. The de-

vice electrically erases all bits within a sector simultaneously via Fowler-Nordheim

tunnelling. The data is programmed using hot electron injection.
