MX29F200T/B
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,
verifies the erase and counts the number of sequences.
A status bit toggling between consecutive read cycles
provides feedback to the user as to the status of the
programming operation.
Register contents serve as inputs to an internal state-
machine which controls the erase and programming
circuitry. During write cycles, the command register
internally latches addresses and data needed for the
programming 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 .
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality,
reliability, and cost effectiveness. The MX29F200T/B
electrically erases all bits simultaneously using Fowler-
Nordheim tunneling. The bytes are programmed by
using the EPROM programming mechanism 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. During a Sector Erase
cycle, the command register will only respond to Erase
Suspend command. After Erase Suspend is complete,
the device stays in read mode. After the state machine
has completed its task, it will allow the command register
to respond to its full command set.
AUTOMATIC PROGRAMMING
The MX29F200T/B is byte programmable using the
Automatic Programming algorithm. The Automatic Pro-
gramming algorithm does not require the system to time
out sequence or verify the data programmed. The
typical chip programming time of the MX29F200T/B at
room temperature is less than 2 seconds.
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 two second. The Automatic Erase algorithm
automatically programs the entire array prior to electrical
erase. The timing and verification of electrical erase are
internally controlled by the device.
AUTOMATIC SECTOR ERASE
The MX29F200T/B is sector(s) erasable using MXIC's
Auto Sector Erase algorithm. Sector erase modes allow
sectors of the array to be erased in one erase cycle. The
Automatic Sector Erase algorithm automatically pro-
grams the specified sector(s) prior to electrical erase.
The timing and verification of electrical erase are inter-
nally controlled by the device.
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm requires the
user to only write program set-up commands (include 2
unlock write cycle and A0H) and a program command
(program data and address). The device automatically
times the programming pulse width, verifies the pro-
gram, and counts the number of sequences. A status bit
similar to DATA polling and a status bit toggling between
consecutive read cycles, provides feedback to the user
as to the status of the programming operation.
