Chip Erase Cycle
The F29C51004T/F29C51004B features a chip-
erase operation. The chip 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 chip erase command (see Table 2).
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
of the F29C51004T/F29C51004B during a
program (erase/write) cycle: DATA Polling (I/O
7
)
and Toggle Bit (I/O
6
).
DATA Polling (I/O
7
)
The F29C51004T/F29C51004B 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 F29C51004T/F29C51004B 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 Enabling/Disabling
The F29C51004T/F29C51004B 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
disabled 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 Mode
The F29C51004T/F29C51004B features an
Autoselect mode to identify boot block locking
status, device ID and manufacturer ID.
Entering Autoselect mode is accomplished by
applying a high voltage (VH) to the A9 Pin, or
through a sequence of commands (as shown in
table 2). Device will exit this mode once high
voltage on A9 is removed or another command is
loaded into the device.
