3. GENERAL DESCRIPTION
The F49L800UA/F49L800BA is a 8 Megabit, 3V only
CMOS Flash memory device organized as 1M bytes of 8
bits or 512K 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 of 70 ns and 90 ns, the
F49L800UA/F49L800BA
allows
high-speed microprocessors. The device has separate
chip enable
CE
, write enable
WE
, and output enable
OE
controls. ESMT's memory devices reliably store memory
data even after 100,000 program and erase cycles.
The F49L800UA/F49L800BA is entirely pin and
command set compatible with the JEDEC standard for 8
Megabit Flash memory devices. Commands are written to
the command register using standard microprocessor
write timings.
the
operation
of
The F49L800UA/F49L800BA features a sector erase
architecture. The device memory array is divided into one
16 Kbytes, two 8 Kbytes, one 32 Kbytes, and fifteen 64
Kbytes. 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.
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
CC
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.
