MX26LV800T/B

REV. 1.3, APR. 13, 2005

AUTOMATIC PROGRAMMING

The MX26LV800T/B is word/byte programmable using

the Automatic Programming algorithm. The Automatic

Programming algorithm makes the external system do

not need to have time out sequence nor to verify the

data programmed. The typical chip programming time

at room temperature of the MX26LV800T/B is less than

35 seconds.

AUTOMATIC PROGRAMMING ALGORITHM

MXIC's Automatic Programming algorithm requires the

user to only write program set-up commands (including

2 unlock write cycle and A0H) and a program command

(program data and address). The device automatically

times the programming pulse width, provides the pro-

gram verification, and counts the number of sequences.

A status bit similar to DATA# polling and a status bit

toggling between consecutive read cycles, provide feed-

back to the user as to the status of the programming

operation. Refer to write operation status, table 7, for more

information on these status bits.

AUTOMATIC CHIP ERASE

The entire chip is bulk erased using 10 ms erase pulses

according to MXIC's Automatic Chip Erase algorithm.

Typical erasure at room temperature is accomplished in

less than 40 second. The Automatic Erase algorithm

automatically programs the entire array prior to electri-

cal erase. The timing and verification of electrical erase

are controlled internally within the device.

AUTOMATIC SECTOR ERASE

The MX26LV800T/B is sector(s) erasable using MXIC's

Auto Sector Erase algorithm. The Automatic Sector

Erase algorithm automatically programs the specified

sector(s) prior to electrical erase. The timing and verifi-

cation of electrical erase are controlled internally within

the device. An erase operation can erase one sector,

multiple sectors, or the entire device.

AUTOMATIC ERASE ALGORITHM

MXIC's Automatic Erase algorithm requires the user to

write commands to the command register using stan-

dard microprocessor write timings. The device will auto-

matically pre-program and verify the entire array. Then

the device automatically times the erase pulse width,

provides the erase verification, and counts the number

of sequences. A status bit toggling between consecu-

tive read cycles provides feedback to the user as to the

status of the erasing operation.

Register contents serve as inputs to an internal state-

machine which controls the erase and programming cir-

cuitry. During write cycles, the command register inter-

nally latches address and data needed for the program-

ming and erase operations. During a system write cycle,

addresses are latched on the falling edge, and data are

latched on the rising edge of WE# or CE#, whichever

happens first.

MXIC's high speed Flash technology combines years of

EPROM experience to produce the highest levels of

quality, reliability, and cost effectiveness. The

MX26LV800T/B electrically erases all bits simulta-

neously using Fowler-Nordheim tunneling. The bytes are

programmed by using the EPROM programming mecha-

nism of hot electron injection.

During a program cycle, the state-machine will control

the program sequences and command register will not

respond to any command set. After the state machine

has completed its task, it will allow the command regis-

ter to respond to its full command set.

AUTOMATIC SELECT

The auto select mode provides manufacturer and de-

vice identification, through identifier codes output on

Q7~Q0. This mode is mainly adapted for programming

equipment on the device to be programmed with its pro-

gramming algorithm.When programming by high voltage

method, automatic select mode requires VID (11V to

12V) on address pin A9 and other address pin A6, A1

and A0 as referring to Table 3. In addition, to access the

automatic select codes in-system, the host can issue

the automatic select command through the command

register without requiring VID, as shown in table 5.
