General Description
operations. Reading data out of the device is similar to reading
from other Flash or EPROM devices.
The A29010 is a 5.0 volt-only Flash memory organized as
131,072 bytes of 8 bits each. The 128 Kbytes of data are
further divided into four 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 A29010 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 A29010 can
also be programmed in standard EPROM programmers.
The A29010 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 A29010
has a second toggle bit, I/O2, to indicate whether the addressed
sector is being selected for erase. The A29010 also offers the
ability to program in the Erase Suspend mode. The standard
A29010 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 chip enable
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 host system can detect whether a program or erase
operation is complete by reading the I/O7 (
Polling) and

I/O6 (toggle) status bits. After a program or erase cycle has
been completed, the device is ready to read array data or
accept another command.
The sector erase architecture allows memory sectors to be
erased and reprogrammed without affecting the data contents
of other sectors. The A29010 is fully erased when shipped from
the factory.
The hardware sector protection feature disables operations for
both program and erase in any combination of the sectors
of memory. This can be achieved via programming equipment.
The Erase Suspend feature enables the user to put erase on
hold for any period of time to read data from, or program data
to, any other sector that is not selected for erasure. True
background erase can thus be achieved.

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 A29010 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
Power consumption is greatly reduced when the device is
placed in the standby mode.
