The A29800 is a 5.0 volt only Flash memory organized as  
1048,576 bytes of 8 bits or 524,288 words of 16 bits each. The  
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 A29800 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.  
A29800 offers the  
function. The 1024 Kbytes of data  
RESET  
are further divided into nineteen sectors for flexible sector erase  
capability. The 8 bits of data appear on I/O0 - I/O7 while the  
addresses are input on A1 to A18; the 16 bits of data appear on  
I/O0~I/O15. The A29800 is offered in 44-pin SOP and 48-Pin  
TSOP 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 A29800 can also be programmed in  
standard EPROM programmers.  
The A29800 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 A29800 has a  
second toggle bit, I/O2, to indicate whether the addressed sector  
is being selected for erase. The A29800 also offers the ability to  
program in the Erase Suspend mode. The standard A29800  
offers access times of 55, 70 and 90 ns, allowing high-speed  
microprocessors to operate without wait states. To eliminate bus
