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 A29001 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  
The A29001 is a 5.0 volt-only Flash memory organized as  
131,072 bytes of 8 bits each. The A29001 offers the  
RESET  
function, but it is not available on A290011. The 128 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 A16. The A29001 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  
A29001 can also be programmed in standard EPROM  
programmers.  
The A29001 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 A29001  
has a second toggle bit, I/O2, to indicate whether the  
addressed sector is being selected for erase. The A29001 also  
offers the ability to program in the Erase Suspend mode. The  
standard A29001 offers access times of 55, 70 and 90 ns  
allowing high-speed microprocessors to operate without wait  
states. To eliminate bus contention the device has separate  
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.
