General Description
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/O
0
- I/O
7
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/O
6
, which indicates
whether an Embedded Program or Erase is in progress, or it
is in the Erase Suspend. Besides the I/O
6
toggle bit, the
A29010 has a second toggle bit, I/O
2
, 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 (
CE
), write enable (
WE
) and output
enable (
OE
) controls.
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 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.
