V29C31004T/V29C31004B Rev. 0.3 October 2000

MOSEL VITELIC

V29C31004T/V29C31004B

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 V29C31004T/V29C31004B is shipped fully

erased (all bits = 1).

Chip Erase Cycle

The V29C31004T/V29C31004B 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 V29C31004T/V29C31004B during a

program (erase/write) cycle: DATA Polling (I/O7)

and Toggle Bit (I/O6).

DATA Polling (I/O7)

The V29C31004T/V29C31004B 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.

Toggle Bit (I/O6)

The V29C31004T/V29C31004B 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.

Boot Block Protection Enabling/Disabling

The V29C31004T/V29C31004B 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 V29C31004T/V29C31004B 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.
