The V29C51400T/V29C51400B is a high speed
262,144 x 16 bit or 524,288 x 8-bit CMOS flash
memory. Writing or erasing the device is done with
a single 5 Volt power supply. The device has
separate chip enable CE, write enable WE, and
output enable OE controls to eliminate bus
contention.
The V29C51400T/V29C51400B offers a combination of: Boot Block with Sector Erase/Write
Mode. The end of write/erase cycle is detected by
DATA Polling of I/O7 or by the Toggle Bit I/O6.
The V29C51400T/V29C51400B features a
sector erase operation which allows each sector to
be erased and reprogrammed without affecting
data stored in other sectors. The device also
supports full chip erase.
Boot block architecture enables the device to
boot from a protected sector located either at the
top (V29C51400T) or the bottom (V29C51400B).
All inputs and outputs are CMOS and TTL
compatible.
The V29C51400T/V29C51400B is ideal for
applications that require updatable code and data
storage.

BYTE MODE

World/Byte Configuration
Output Disable
The BYTE pin controls whether the device data
I/O pins I/O0-I/O15 operate in the byte or word
configuration. If the BYTE pin is set at logic ’1’, the
device is in word configuration, I/O0-I/O15 are
active and controlled by CE and OE.
If BYTE pin is set at logic ’0’, the device is in byte
configuration, and only data I/O pins I/O0-I/O7 are
active and controlled by CE and OE. The data I/O
pins I/O8-I/O14 are tri-stated, and the I/O15 pin is
used as an input for the LSB (A-1) address
function.
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 input state.
Command Sequence
The V29C51400T/V29C51400B does not
provide the “reset” feature to return the chip to its
normal state when an incomplete command
sequence or an interruption has happened. In this
case, normal operation (Read Mode) can be
restored by issuing a “non-existent” command
sequence, for example Address: 5555H, Data FFH.
Functional Description
The V29C51400T/V29C51400B consists of 512
equally-sized sectors of 512 bytes each. The 16 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 V29C51400 is available in two versions: the
V29C51400T with the Boot Block address starting
from 7C000H to 7FFFFH, and the V29C51400B
with the Boot Block address starting from 00000H
to 3FFFH.
Byte Write Cycle
The V29C51400T/V29C51400B is programmed
on a byte-by-byte basis. The byte write 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 write 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 write cycle
can be CE controlled or WE controlled.
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).

Sector Erase Cycle
erase command (see Table 2). A sector must be first
erased before it can be re-written. 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 status.
The V29C51400T/V29C51400B is shipped fully
erased (all bits = 1).
The V29C51400T/V29C51400B 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

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”.
The V29C51400T/V29C51400B features a chiperase operation. The chip erase operation is
initiated by using a specific six-bus-cycle
sequence: two unlock program cycles, a setup

Program Cycle Status Detection
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.
There are two methods for determining the state
of the V29C51400T/V29C51400B during a
program (erase/write) cycle: DATA Polling (I/O7)
and Toggle Bit (I/O6).
DATA Polling (I/O7)
The V29C51400T/V29C51400B 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/O7. Once the
program cycle is completed, I/O7 will show true
data, and the device is then ready for the next cycle.
Boot Block Protection Status
In Autoselect mode, performing a read at
address location 7BXX2H (V29C51400T) or
0CXX2H (V29C51400B) will indicate boot block
protection status. If the data is 01H, the boot block
is protected. If the data is 00H, the boot block is
unprotected. This is also shown is table 3.
Toggle Bit (I/O6)
The V29C51400T/V29C51400B 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/O6 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.
Device ID
Boot Block Protection Enabling/Disabling
In Autoselect mode, performing a read at
address XXXX0H will determine the manufacturer
ID. 40H is the manufacturer code for Mosel Vitelic
Flash.
In Autoselect mode, performing a read at
address XXX1H will determine whether the device
is a Top Boot Block device or a Bottom Boot Block
device. If the data is 13H, the device is a Top Boot
Block. If the data is B3H, the device is a Bottom
Boot Block device (see Table 3).
Manufacturer ID
The V29C51400T/V29C51400B 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.
Hardware Data Protection
VCC Detection: the program operation is inhibited
when VCC is less than 3.5V.
Noise Protection: a CE or WE pulse of less than
5ns will not initiate a program cycle.
Program Inhibit: holding any one of OE LOW, CE
HIGH or WE HIGH inhibits a program cycle.
Autoselect Mode
The V29C51400T/V29C51400B features an
Autoselect mode to identify boot block locking
