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 of 70 ns and 90 ns, the
F49L320UA/F49L320BA allows the operation of 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 F49L320UA/F49L320BA is entirely pin and command
set compatible with the JEDEC standard for 32 Megabit
Flash memory devices. Commands are written to the
command register using standard microprocessor write
timings. Register contents serve as input to an internal
state-machine that controls the erase and programming
circuitry. Write cycles also internally latch addresses and
data needed for the programming and erase operations.
Reading data out of the device is similar to reading from
other Flash or EPROM devices.
F49L320UA/F49L320BA (2F)
The F49L320UA/F49L320BA features a sector erase
architecture. The device array is divided into eight 8KB,
sixty-three 64KB for 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.
The sector group protect/chip 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. The command
register using standard microprocessor write timings.
