Description
The AT49BV/LV040(T) 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
technology, the devices offer access times to 70 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(chǔ).
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?.
