Description

AT49F008A

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.

AT49F8192AT

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.
