3. GENERAL DESCRIPTION
The F49L320UA/F49L320BA is a 32 Megabit, 3V only CMOS
Flash memory device organized as 4M bytes of 8 bits or 2M
words of 16bits. This device is packaged in standard 48-pin
TSOP. It is designed to be programmed and erased both in
system and can in standard EPROM programmers.
With access times
F49L320UA/F49L320BA allows the operation of high-speed
microprocessors. The device has separate chip enable CE , write
enable , and output enable OE controls. ESMT's memory
WE
devices reliably store memory data even after 100,000 program
and erase cycles.
The F49L320UA/F49L320BA is entirely pin and command set
compatible with the JEDEC standard for 32 Megabit Flash
memory devices. Commands are written to
The F49L320UA/F49L320BA features a sector erase architecture.
The device array is divided into eight 8KB, sixty-three 64KB for
Elite Semiconductor Memory Technology Inc.

byte mode. The device memory array is divided into eight 4K
word, sixty-three 32K word sectors for word mode. Sectors can
be erased individually or in groups without affecting the data in
other sectors. Multiple-sector erase and whole chip erase
capabilities provide the flexibility to revise the data in the
device.
ns, the
The sector protect/unprotect feature disables both program and
erase operations in any combination of the sectors of the
memory. This can be achieved in-system or via programming
equipment.
A low V detector inhibits write operations on loss of power.
CC
End of program or erase is detected by the Ready/Busy status
pin, Data Polling of DQ7, or by the Toggle Bit I feature on DQ6.
Once the program or erase cycle has been successfully
completed, the device internally resets to the Read mode. The
