Am28F512
write cycles, the command register internally latches
address and data needed for the programming and
erase operations. For system design simplification, the
Am28F512 is designed to support either WE# or CE#
controlled writes. During a system write cycle, ad-
dresses are latched on the falling edge of WE# or CE#
whichever occurs last. Data is latched on the rising edge
of WE# or CE# whichever occurs first. To simplify the fol-
lowing discussion, the WE# pin is used as the write cycle
control pin throughout the rest of this text. All setup and
hold times are with respect to the WE# signal.
AMD’s Flash technology combines years of EPROM
and EEPROM experience to produce the highest levels
of quality, reliability, and cost effectiveness. The
Am28F512 electrically erases all bits simultaneously
using Fowler-Nordheim tunneling. The bytes are pro-
grammed one byte at a time using the EPROM
programming mechanism of hot electron injection.
