3. GENERAL DESCRIPTION  
The F49B002UA is a 2 Megabit, 5V only CMOS Flash  
memory device organized as 128K bytes of 8 bits. This  
device is packaged in standard 32-pin PDIP and 32-pin  
PLCC. It is designed to be programmed and erased both in  
system and can in standard EPROM programmers.  
The F49B002UA features a sector erase architecture.  
The device memory array is divided into 16 Kbytes, 8K  
bytes, 8Kbytes, 96Kbytes, 128Kbytes. Erase capabilities  
provide the flexibility to revise the data in the device.  
A low V
CC
detector inhibits write operations on loss of  
power. End of program or erase is detected by the Data  
Polling of DQ7, or by the Toggle Bit feature on DQ6. Once  
the program or erase cycle has been successfully  
completed, the device internally resets to the Read mode.  
With access times of 70 ns and 90 ns, the F49B002UA  
allows the operation of high-speed microprocessors. The  
device has separate chip enable  
, write enable  
,
WE  
CE  
and output enable  
controls. EFST's memory devices  
OE  
reliably store memory data even after 10,000 program and  
erase cycles.  
The F49B002UA is entirely pin and command set  
compatible with the JEDEC standard for 2 Megabit Flash  
memory devices. Commands are written to the command  
register using standard microprocessor write timings.
