Am28F020
addresses and data needed for the programming and
erase operations. For system design simplification, the
Am28F020 is designed to support either WE# or CE#
controlled writes. During a system write cycle,
addresses 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
discussion, the WE# pin is used as the write cycle
control pin throughout the rest of this data sheet. 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
Am28F020 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.
