Features
Description
The AT49BV/LV080 are 3-volt-only in-system Flash Memory devices. Their 8 mega-
bits of memory are organized as 1,024,576 words by 8 bits. Manufactured with At-
mel’s advanced nonvolatile CMOS technology, the devices offer access times to 120
ns with power dissipation of just 90 mW over the commercial temperature range.
When the device is deselected, the CMOS standby current is less than 50 A.
The device contains a user-enabled "boot block" protection feature. Two versions of
the feature are available: the AT49BV/LV080 locates the boot block at lowest order
addresses ("bottom boot"); the AT49BVLV080T locates it at highest order addresses
("top boot").
