3. GENERAL DESCRIPTION
The F49L160UA/F49L160BA is a 16 Megabit, 3V only
CMOS Flash memory device organized as 2M bytes of 8
bits or 1M 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
F49L160UA/F49L160BA allows the operation of
high-speed microprocessors. The device has separate
chip enable
CE
, write enable
WE
, and output enable
OE
controls. EFST's memory devices reliably store
memory data even after 100,000 program and erase
cycles.
The F49L160UA/F49L160BA is entirely pin and
command set compatible with the JEDEC standard for 16
Megabit Flash memory devices. Commands are written to
the command register using standard microprocessor
write timings.
The F49L160UA/F49L160BA features a sector erase
architecture. The device array is divided into one 16KB,
two 8KB, one 32KB, and thirty-one 64KB for byte mode.
The device memory array is divided into one 8K word, two
4K word, one 16K word, and thirty-one 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 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.
