MX29LV320AT/B  
The MX29LV320AT/B uses a 2.7V to 3.6V VCC  
supply to perform the High Reliability Erase and  
auto Program/Erase algorithms.  
modes allow sectors of the array to be erased in one  
erase cycle. The Automatic Sector Erase algorithm  
automatically programs the specified sector(s) prior to  
electrical erase. The timing and verification of  
electrical erase are controlled internally within the  
device.  
The highest degree of latch-up protection is  
achieved with MXIC's proprietary non-epi process.  
Latch-up protection is proved for stresses up to 100  
milliamperes on address and data pin from -1V to  
VCC + 1V.  
AUTOMATIC ERASE ALGORITHM  
MXIC's Automatic Erase algorithm requires the user to  
write commands to the command register using stand-  
ard 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 programming operation.  
AUTOMATIC PROGRAMMING  
The MX29LV320AT/B is byte/word 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 MX29LV320AT/B is less than  
36 seconds.  
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 .  
AUTOMATIC PROGRAMMING ALGORITHM  
MXIC's Automatic Programming algorithm require the user  
to only write program set-up commands (including 2 un-  
lock write cycle and A0H) and a program command (pro-  
gram data and address). The device automatically times  
the programming pulse width, provides the program veri-  
fication, and counts the number of sequences. A status  
bit similar to DATA polling and a status bit toggling be-  
tween consecutive read cycles, provide feedback to the  
user as to the status of the programming operation.  
MXIC's Flash technology combines years of EPROM  
experience to produce the highest levels of quality, relia-  
bility, and cost effectiveness.The MX29LV320AT/B elec-  
trically erases all bits simultaneously using Fowler-Nord-  
heim tunneling. The bytes/words are programmed by  
using the EPROM programming mechanism of hot elec-  
tron injection.  
AUTOMATIC CHIP ERASE  
During a program cycle, the state-machine will control  
the program sequences and command register will not  
respond to any command set. During a Sector Erase  
cycle, the command register will only respond to Erase  
Suspend command. After Erase Suspend is completed,  
the device stays in read mode. After the state machine  
has completed its task, it will allow the command regis-  
ter to respond to its full command set.  
The entire chip is bulk erased using 50 ms erase pulses  
according to MXIC's Automatic Chip Erase algorithm.  
Typical erasure at room temperature is accomplished in  
less than 35 seconds. 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 MX29LV320AT/B is sector(s) erasable using  
MXIC's Auto Sector Erase algorithm. Sector erase
