Description
The V29C51004T/V29C51004B is a high speed
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 V29C51004T/V29C51004B offers a combi-
nation 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 V29C51004T/V29C51004B 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 (V29C51004T) or the bottom (V29C51004B).
All inputs and outputs are CMOS and TTL
compatible.
The V29C51004T/V29C51004B is ideal for
applications that require updatable code and data
storage.

Boot Block Protection Status
In Autoselect mode, performing a read at
address location 3CXX2H (V29C51004T) or
0CXX2H (V29C51004B) 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.
Device ID
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 03H, the device is a Top Boot
Block. If the data is A3H, the device is a Bottom
Boot Block device (see Table 3).
V29C51004T/V29C51004B
Manufacturer ID
In Autoselect mode, performing a read at
address XXXX0H will determine the manufacturer
ID. 40H is the manufacturer code for Mosel Vitelic
Flash.
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.
