General Description
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
A29800 offers the
are further divided into nineteen sectors for flexible sector erase
capability. The 8 bits of data appear on I/O
addresses are input on A1 to A18; the 16 bits of data appear on
I/O
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/O
an Embedded Program or Erase is in progress, or it is in the
Erase Suspend. Besides the I/O
second toggle bit, I/O
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

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.
