General Description
The A29L800A is an 8Mbit, 3.0 volt-only Flash memory
organized as 1,048,576 bytes of 8 bits or 524,288 words of 16
bits each. The 8 bits of data appear on I/O
0
- I/O
7
; the 16 bits of
data appear on I/O
0
~I/O
15
. The A29L800A is offered in 48-ball
TFBGA,
44-pin SOP and 48-Pin TSOP packages. This device
is designed to be programmed in-system with the standard
system 3.0 volt VCC supply. Additional 12.0 volt VPP is not
required for in-system write or erase operations. However, the
A29L800A can also be programmed in standard EPROM
programmers.
The A29L800A 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
A29L800A has a second toggle bit, I/O
2
, to indicate whether
the addressed sector is being selected for erase. The
A29L800A also offers the ability to program in the Erase
Suspend mode. The standard A29L800A offers access times
of 70 and 90ns, 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 3.0 volt power supply for
both read and write functions. Internally generated and
regulated voltages are provided for the program and erase
operations.
The A29L800A is entirely software command set compatible
with
the
JEDEC
single-power-supply
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
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 Unlock Bypass mode facilitates faster
programming times by requiring only two write cycles to
program data instead of four.
The host system can detect whether a program or erase
operation is complete by observing the RY /
BY
pin, or
by
reading the I/O

(

(toggle) status bits.
