General Description  
The device requires only a single 5.0 volt power supply for both  
read and write functions. Internally generated and regulated  
voltages are provided for the program and erase operations.  
The A29002 is entirely software command set compatible with  
the JEDEC single-power-supply Flash standard. 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.  
Device programming occurs by writing the proper program  
command sequence. This initiates the Embedded Program  
algorithm - an internal algorithm that automatically times the  
program pulse widths and verifies proper program margin.  
Device erasure occurs by executing the proper erase command  
sequence. This initiates the Embedded Erase algorithm - an  
internal algorithm that automatically preprograms the array (if it  
is not already programmed) before executing the erase  
operation. During erase, the device automatically times the  
erase pulse widths and verifies proper erase margin.  
The A29002 is a 5.0 volt-only Flash memory organized as  
262,144 bytes of 8 bits each. The A29002 offers the  
RESET  
function, but it is not available on A290021. The 256 Kbytes  
of data are further divided into seven sectors for flexible  
sector erase capability. The 8 bits of data appear on I/O0 -  
I/O7 while the addresses are input on A0 to A17. The A29002  
is offered in 32-pin PLCC, TSOP, and PDIP packages. This  
device is designed to be programmed in-system with the  
standard system 5.0 volt VCC supply. Additional 12.0 volt  
VPP is not required for in-system write or erase operations.  
However, the A29002 can also be programmed in standard  
EPROM programmers.  
The A29002 has the first toggle bit, I/O6, which indicates  
whether an Embedded Program or Erase is in progress, or it  
is in the Erase Suspend. Besides the I/O6 toggle bit, the  
A29002 has a second toggle bit, I/O2, to indicate whether the  
addressed sector is being selected for erase. The A29002  
also offers the ability to program in the Erase Suspend mode.  
The standard A29002 offers access times of 55, 70, 90, 120,  
and 150 ns, allowing high-speed microprocessors to operate  
without wait states. To eliminate bus contention the device  
has separate chip enable (  
), write enable (  
) and  
WE  
CE  
output enable (  
) controls.
