INTRODUCTION
The Aeroflex 64Mbit, 3.3 volt-only flash memory device, can
be organized as 4,194,304 words of 16-bits each or 8,388,608
bytes of 8-bits each. Word mode data appears on DQ[15:0];
byte mode data appears on DQ[7:0]. The device is designed to
be programmed in-system with the standard 3.3 volt VCC
supply and can also be programmed in standard PROM
programmers. The device is available with an access time of
60 ns and is offered in a 48-pin ceramic flatpack package.
Standard control pins—Chip Enable (CE#), Write Enable
(WE#), and Output Enable (OE#)—control normal read and
write operations, and avoid bus contention issues. The device
operates from a single 3.3 volt power supply.
APPLICATION
The UT8QNF8M8 64Mbit Flash Memory is compatible for use
with the UT699 LEON 3FT microprocessor. In a typical
application, the microprocessor transfers an image of the
application program or kernel from non-volatile memory, such
as flash, to volatile memory, such as SRAM. The Aeroflex
64Mbit NOR Flash is intended to provide customers with a non-
volatile solution that has a memory capacity large enough to
house a typical application program or kernel.
