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.
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.
With access times of 70 ns and 90 ns, the
F49L320UA/F49L320BA allows the operation of high-speed
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.

devices reliably store memory data even after 100,000 program
and erase cycles.
A low VCC detector inhibits write operations on loss of power.
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
