Description

The AT49(H)BV010 and the AT49(H)LV010 are 3-volt-only, 1-megabit Flash memo-

ries organized as 131,072 words of 8 bits each. Manufactured with Atmel’s advanced

nonvolatile CMOS technology, the devices offer access times to 55 ns with power dis-

sipation of just 90 mW over the commercial temperature range. When the devices are

deselected, the CMOS standby current is less than 50 A.

To allow for simple in-system reprogrammability, the AT49(H)BV/(H)LV010 does not

require high input voltages for programming. Three-volt-only commands determine

the read and programming operation of the device. Reading data out of the device is

similar to reading from an EPROM. Reprogramming the AT49(H)BV/(H)LV010 is

performed by erasing the entire 1 megabit of memory and then programming on a

byte by byte basis. The typical byte programming time is a fast 30 s. The end of a

program cycle can be optionally detected by the DATA polling feature. Once the end

of a byte program cycle has been detected, a new access for a read or program can

begin. The typical number of program and erase cycles is in excess of 10,000 cycles.

... This dual-line control gives designers flexibility in pre- venting bus contention. ERASURE: Before a byte can be reprogrammed, the 128K bytes memory array (or 120K bytes if the boot block fea- tured is used) must be erased. The erased state of the memory bits is a logical “1”. The entire device can be erased at one time by using a 6-byte software code ...
