AT49F001(N)(T)
2
When the device is deselected, the CMOS standby current
is less than 100
µA. For the AT49F001NT pin 1 for the DIP
and PLCC packages and pin 9 for the TSOP package are
don’t connect pins.
To allow for simple in-system reprogrammability, the
AT49F001(N)(T) does not require high input voltages for
programming. Five-volt-only commands determine the read
and programming operation of the device. Reading data
out of the device is similar to reading from an EPROM; it
has standard CE, OE, and WE inputs to avoid bus conten-
tion. Reprogramming the AT49F001(N)(T) is performed by
erasing a block of data and then programming on a byte by
byte basis. The byte programming time is a fast 50
µs. The
end of a program cycle can be optionally detected by the
DATA polling feature. Once the end of a byte program
cycle has been detected, a new access for a read or pro-
gram can begin. The typical number of program and erase
cycles is in excess of 10,000 cycles.
The device is erased by executing the erase command
sequence; the device internally controls the erase opera-
tions. There are two 8K byte parameter block sections and
two main memory blocks.
The device has the capability to protect the data in the boot
block; this feature is enabled by a command sequence.
The 16K-byte boot block section includes a reprogramming
lock out feature to provide data integrity. The boot sector is
designed to contain user secure code, and when the fea-
ture is enabled, the boot sector is protected from being
reprogrammed.
In the AT49F001N(T), once the boot block programming
lockout feature is enabled, the contents of the boot block
ar e pe r mane nt and ca nnot b e chang ed. I n the
AT49F001(T), once the boot block programming lockout
feature is enabled, the contents of the boot block cannot be
changed with input voltage levels of 5.5 volts or less.
