Description
The AT49F040 is a 5-volt-only in-system Flash Memory. Its 4 megabits of memory is
organized as 524,288 words by 8 bits. Manufactured with Atmel’s advanced nonvola-
tile CMOS technology, the device offers access times to 70 ns with power dissipation
of just 275 mW over the commercial temperature range. When the device is dese-
lected, the CMOS standby current is less than 100
μ
A.
The device contains a user-enabled “boot block” protection feature. Two versions of
the feature are available: the AT49F040 locates the boot block at lowest order
addresses (“bottom boot”); the AT49F040T locates it at highest order addresses (“top
boot”).
