Description
The AT49BV/LV040 are 3-volt-only, 4-megabit Flash memories organized as 524,288
words of 8-bits each. Manufactured with Atmel鈥檚 advanced nonvolatile CMOS tech-
nology, 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
碌A.
The device contains a user-enabled 鈥渂oot block鈥?protection feature. Two versions of
the feature are available: the AT49BV/LV040 locates the boot block at lowest order
addresses (鈥渂ottom boot鈥?; the AT49BV/LV040T locates it at highest order addresses
(鈥渢op boot鈥?.
