General Description
The S29GL256/128/064/032M family of devices are 3.0 V single power Flash memory manufac-
tured using 0.23 µm MirrorBit technology. The S29GL256M is a 256†Mbit, organized as
16,777,216 words or 33,554,432 bytes. The S29GL128M is a 128 Mbit, organized as 8,388,608
words or 16,777,216 bytes. The S29GL064M is a 64 Mbit, organized as 4,194,304 words or
8,388,608 bytes. The S29GL032M is a 32 Mbit, organized as 2,097,152 words or 4,194,304
bytes. Depending on the model number, the devices have an 8-bit wide data bus only, 16-bit wide
data bus only, or a 16-bit wide data bus that can also function as an 8-bit wide data bus by using
the BYTE# input. The devices can be programmed either in the host system or in standard EPROM
programmers.
Access times as fast as 90 ns (S29GL128M, S29GL064M, S29GL032M) or 100 ns (S29GL256M)
are available. Note that each access time has a specific operating voltage range (V
CC
) as specified
in
Product Selector Guide
and
Ordering Information.
Package offerings include 40-pin TSOP, 48-
pin TSOP, 56-pin TSOP, 48-ball fine-pitch BGA, 63-ball fine-pitch BGA and 64-ball Fortified BGA,
depending on model number. Each device has separate chip enable (CE#), write enable (WE#)
and output enable (OE#) controls.
Each device requires only a
single 3.0 volt power supply
for both read and write functions. In
addition to a V
CC
input, a high-voltage
accelerated program (ACC)
feature provides shorter
programming times through increased current on the WP#/ACC input. This feature is intended to
facilitate factory throughput during system production, but may also be used in the field if desired.
The device is entirely command set compatible with the
JEDEC single-power-supply Flash
standard.
Commands are written to the device using standard microprocessor write timing.
Write cycles also internally latch addresses and data needed for the programming and erase
operations.
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.
Device programming and erasure are initiated through command sequences. Once a program or
erase operation starts, the host system need only poll the DQ7 (Data# Polling) or DQ6 (toggle)
status bits
or monitor the
Ready/Busy# (RY/BY#)
output to determine whether the opera-
tion is complete. To facilitate programming, an
Unlock Bypass
mode reduces command
sequence overhead by requiring only two write cycles to program data instead of four.
Hardware data protection
measures include a low V
CC
detector that automatically inhibits write
operations during power transitions. The hardware sector protection feature disables both pro-
gram and erase operations in any combination of sectors of memory. This can be achieved in-
system or via programming equipment.
The
Erase Suspend/Erase Resume
feature allows the host system to pause an erase operation
in a given sector to read or program any other sector and then complete the erase operation. The
Program Suspend/Program Resume
feature enables the host system to pause a program op-
eration in a given sector to read any other sector and then complete the program operation.
The
hardware RESET# pin
terminates any operation in progress and resets the device, after
which it is then ready for a new operation. The RESET# pin may be tied to the system reset cir-
cuitry. A system reset would thus also reset the device, enabling the host system to read boot-
up firmware from the Flash memory device.
The device reduces power consumption in the
standby mode
when it detects specific voltage
levels on CE# and RESET#, or when addresses are stable for a specified period of time.

The
Write Protect (WP#)
feature protects the first or last sector by asserting a logic low on the
WP#/ACC pin or WP# pin, depending on model number. The protected sector is still protected
even during accelerated programming.
The
Secured Silicon Sector
provides a 128-word/256-byte area for code or data that can be
permanently protected. Once this sector is protected, no further changes within the sector can
occur.
Spansion MirrorBit flash technology combines years of Flash memory manufacturing experience
to produce the highest levels of quality, reliability and cost effectiveness. The device electrically
erases all bits within a sector simultaneously via hot-hole assisted erase. The data is programmed
using hot electron injection.
