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(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?.
