Description
The AT29C010A is a 5-volt-only in-system Flash programmable and erasable read
only memory (PEROM). Its 1 megabit of memory is organized as 131,072 words by 8
bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 70 ns with power dissipation of just 275 mW over the commer-
cial temperature range. When the device is deselected, the CMOS standby current is
less than 100 µA. The device endurance is such that any sector can typically be writ-
ten to in excess of 10,000 times.
To allow for simple in-system reprogrammability, the AT29C010A does not require
high input voltages for programming. Five-volt-only commands determine the opera-

Device Operation (Continued)
BOOT BLOCK LOCKOUT DETECTION: A software
method is available to determine whether programming of
either boot block section is locked out. See Software Prod-
uct Identification Entry and Exit sections. When the device
is in the software product identification mode, a read from
location 00002 will show if programming the lower address
boot block is locked out while reading location FFFF2 will
DC and AC Operating Range
do so for the upper boot block. If the data is FE, the corre-
sponding block can be programmed; if the data is FF, the
program lockout feature has been activated and the corre-
sponding block cannot be programmed. The software
product identification exit mode should be used to return to
standard operation.

Notes: 1. A7 through A16 must specify the sector address
during each high to low transition of WE (or CE).
2. OE must be high when WE and CE are both low.
3. All bytes that are not loaded within the sector being
programmed will be indeterminate.
