F29C51001T/F29C51001B
Functional Description
The
F29C51001T/F29C51001B consists of 256
equally-sized sectors of 512 bytes each. The 8 KB
lockable Boot Block is intended for storage of the
system BIOS boot code. The boot code is the first
piece of code executed each time the system is
powered on or rebooted.
The
F29C51001 is available in two versions: the
F29C51001T with the Boot Block address starting
from 1E000H to 1FFFFH, and the
F29C51001B
with the Boot Block address starting from 00000H
to 1FFFFH.
Read Cycle
A read cycle is performed by holding both CE
and OE signals LOW. Data Out becomes valid only
when these conditions are met. During a read cycle
WE must be HIGH prior to CE and OE going LOW.
WE must remain HIGH during the read operation
for the read to complete (see Table 1).
Output Disable
Returning OE or CE HIGH, whichever occurs first
will terminate the read operation and place the l/O
pins in the HIGH-Z state.
Standby
The device will enter standby mode when the CE
signal is HIGH. The l/O pins are placed in the
HIGH-Z, independent of the OE signal.
Byte Program Cycle
The
F29C51001T/F29C51001B is programmed
on a byte-by-byte basis. The byte program
operation is initiated by using a specific four-bus-
cycle sequence: two unlock program cycles, a
program setup command and program data
program cycles (see Table 2).
During the byte program cycle, addresses are
latched on the falling edge of either CE or WE,
whichever is last. Data is latched on the rising edge
of CE or WE, whichever is first. The byte program
cycle can be CE controlled or WE controlled.
Sector Erase Cycle
The
F29C51001T/F29C51001B features a
sector erase operation which allows each sector to
be erased and reprogrammed without affecting
data stored in other sectors. Sector erase operation
is initiated by using a specific six-bus-cycle
sequence: Two unlock program cycles, a setup
command, two additional unlock program cycles,
and the sector erase command (see Table 2). A
sector must be first erased before it can be
reprogrammed. While in the internal erase mode,
the device ignores any program attempt into the
device. The internal erase completion can be
determined via DATA polling or toggle bit.
The
F29C51001T/F29C51001B is shipped with
pre-erased sectors (all bits = 1).

Chip Erase Cycle
The
F29C51001T/F29C51001B features a chip-
erase operation. The chip erase operation is
i n i t i a t e d b y u s i n g a s p e c i f i c s i x - b u s - c y c l e
sequence: two unlock program cycles, a setup
command, two additional unlock program cycles,
and the chip erase command (see Table 2).
T h e c h i p e r a s e o p e r a t i o n i s p e r f o r m e d
sequentially, one sector at a time. When the
automated on chip erase algorithm is requested
with the chip erase command sequence, the device
automatically programs and verifies the entire
memory array for an all zero pattern prior to erasure
The automatic erase begins on the rising edge of
the last WE or CE pulse in the command sequence
and terminates when the data on DQ7 is "1".
Program Cycle Status Detection
There are two methods for determining the state
o f t h e
F29C51001T/F29C51001B during a
program (erase/program) cycle: DATA Polling
(I/O
7
) and Toggle Bit (I/O
6
).
DATA Polling (I/O
7
)
The
F29C51001T/F29C51001B features DATA
polling to indicate the end of a program cycle.
When the device is in the program cycle, any
attempt to read the device will received the
complement of the loaded data on I/O
7
. Once the
program cycle is completed, I/O
7
will show true
data, and the device is then ready for the next
cycle.
Toggle Bit (I/O
6
)
The
F29C51001T/F29C51001B also features
another method for determining the end of a
program cycle. When the device is in the program
cycle, any attempt to read the device will result in
l/O
6
toggling between 1 and 0. Once the program is
completed, the toggling will stop. The device is then
ready for the next operation. Examining the toggle
bit may begin at any time during a program cycle.

Boot Block Protection
T h e
F29C51001T/F29C51001B features
hardware Boot Block Protection. The boot block
sector protection is enabled when high voltage
(12.5V) is applied to OE and A9 pins with CE pin
LOW and WE pin lOW. The sector protection is
desabled when high voltage is applied to OE, CE
and A9 pins with WE pin LOW. Other pins can be
HIGH or LOW. This is shown in table 1.
Autoselect
The
F29C51001T/F29C51001B features an
Autoselect mode to identify
the Boot Block
(protected/unprotected), the Device (Top/Bottom),
and the manufacturer ID.
To get to the Autoselect mode, a high voltage
(V
H
) must be applied to the A
9
pin. Once the A
9
signal is returned to LOW or HIGH, the device will
return to the previous mode.
Boot Block Protection Status
In Autoselect mode, performing a read at
address 3CXX2H or address 0CXX2H will indicate
if the Top Boot Block sector or the Bottom Boot
Block sector is locked out. If the data is 01H, the
Top/Bottom Boot Block is protected. If the data is
00H, the Top/Bottom Boot Block is unprotected.
(see Table 3.)
Device ID
In Autoselect mode, performing a read at
address XXXXH will determine whether the device
is a Top Boot Block device or a Bottom Boot Block
device. If the data is 01H, the device is a Top Boot
Block. If the data is A1H, the device is a Bottom
Boot Block device (see Table 3).
In addition, the device ID can also be read via the
command register when the device is erased or
programmed in a system without applying high
voltage to the A
9
pin. When A
0
is HIGH, the device
ID is presented at the outputs.
Manufacturer ID
In Autoselect mode, performing a read at
address. XXXX0H will determine the manufacturer
ID. 40H is the manufacturer code for SyncMOS
Flash.
In addition the manufacturer ID can also be read
via the command register when the device is
erased or programmed in a system without
applying high voltage to the A
9
pin. when A
0
is
LOW, the manufacturer ID is presented at the
outputs.
Hardware Data Protection
V
CC
Sense Protection: the program operation is
inhibited when VCC is less than 2.5V.
Noise Protection: a CE or WE pulse of less than
5ns will not initiate a program cycle.
Program Inhibit Protection: holding any one of
OE LOW, CE HIGH or WE HIGH inhibits a program
cycle.
