GENERAL DESCRIPTION
The Am28F512 is a 512 K bit Flash memory orga-
nized as 64 Kbytes of 8 bits each. AMD’s Flash mem-
ories offer the most cost-effective and reliable read/
write non-volatile random access memory. The
Am28F512 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 Am28F512 is erased when shipped
from the factory.
The standard Am28F512 offers access times as fast as
70 ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the Am28F512 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
Am28F512 uses a command register to manage this
functionality, while maintaining a standard JEDEC
Flash Standard 32-pin pinout. The command register
allows for 100% TTL level control inputs and fixed
power supply levels during erase and programming.
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 Am28F512 uses a
12.0V±5% V
PP
high voltage input to perform 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 mA on ad-
dress and data pins from -1 V to V
CC
+1 V.
The Am28F512 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 Am28F512 is one second.
The entire chip is bulk erased using 10 ms erase pulses
according to AMD’s Flasherase algorithm. Typical era-
sure at room temperature is accomplished in less than
one second. The windowed package and the 15-20
minutes required for EPROM erasure using ultra-violet
light are eliminated.
Commands are written to the command register using
standard microprocessor write timings. Register con-
tents serve as inputs to an internal state-machine which
controls the erase and programming circuitry. During
