Description
The AT49F008A(T) and AT49F8192A(T) are 5-volt, 8-megabit Flash memories orga-
nized as 1,048,576 words of 8 bits each or 512K words of 16 bits each. Manufactured
with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times
to 90 ns with power dissipation of just 275 mW. When deselected, the CMOS standby
current is less than 100 µA.
The device contains a user-enabled “boot block” protection feature. Two versions of
the feature are available: the AT49F008A/8192A locates the boot block at lowest
order addresses (“bottom boot”); the AT49F008AT/8192AT locates it at highest order
addresses (“top boot”).
To allow for simple in-system reprogrammability, the AT49F008A(T)/8192A(T) does
not require high-input voltages for programming. Reading data out of the device is
similar to reading from an EPROM; it has standard CE, OE and WE inputs to avoid
bus contention. Reprogramming the AT49F008A(T)/8192A(T) is performed by first
erasing a block of data and then programming on a byte-by-byte or word-by-word
basis.

... This feature does not have to be activated; the boot block’s usage as a write-protected region is optional to the user. The address range of the boot block is 00000H to 03FFFH for the AT49F008A; FC000H to FFFFFH for the AT49F008AT; 00000H to 01FFFH for the AT49F8192A; and 7E000H to 7FFFFH for the AT49F8192AT. ...
