GENERAL DESCRIPTION
The Am28F010 is a 1 Megabit Flash memory orga-
nized as 128 Kbytes of 8 bits each. AMD’s Flash mem-
ories offer the most cost-effective and reliable read/
write non-volatile random access memor y. The
Am28F010 is packaged in 32-pin PDIP, PLCC, and
TSOP versions. It is designed to be reprogrammed
and erased in-system or in standard EPROM pro-
grammers. The Am28F010 is erased when shipped
from the factory.
The standard Am28F010 offers access times as fast as
70 ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the Am28F010 has separate chip enable (CE#) and
output enable (OE#) controls.
AMD’s Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
Am28F010 uses a command register to manage this
functionality, while maintaining a JEDEC Flash Stan-
dard 32-pin pinout. The command register allows for
100% TTL level control inputs and fixed power supply
levels during erase and programming, while maintain-
ing maximum EPROM compatibility.
AMD’s Flash technology reliably stores memory con-
tents even after 10,000 erase and program cycles. The
AMD cell is designed to optimize the erase and pro-
gramming mechanisms. In addition, the combination of
advanced tunnel oxide processing and low internal
electric fields for erase and programming operations
produces reliable cycling. The Am28F010 uses a
12.0 V
± 5% V
PP high voltage input to perfor m the
Flasherase and Flashrite algorithms.
The highest degree of latch-up protection is achieved
with AMD’s proprietary non-epi process. Latch-up pro-
tection is provided for stresses up to 100 milliamps on
address and data pins from –1 V to VCC +1 V.
The Am28F010 is byte programmable using 10 ms pro-
gramming pulses in accordance with AMD’s Flashrite
programming algorithm. The typical room temperature
programming time of the Am28F010 is two seconds.
The entire chip is bulk erased using 10 ms erase pulses
according to AMD’s Flasherase alrogithm. Typical era-
sure at room temperature is accomplished in less than
one second. The windowed package and the 15–20
