multiple program command sequence
Top or bottom boot block configurations available
Embedded Algorithms
- Embedded Erase algorithm will automatically erase the
entire chip or any combination of designated sectors and
verify the erased sectors
- Embedded Program algorithm automatically writes and
verifies data at specified addresses

Erase Suspend/Erase Resume
-
Suspends a sector erase operation to read data from, or
program data to, a non-erasing sector, then resumes the
erase operation

General Description
The A29160 is a 16Mbit, 5.0 volt-only Flash memory
organized as 2,097,152 bytes of 8 bits or 1,048,576 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 is offered in 48-ball
FBGA, 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 A29160 can also be programmed in standard EPROM
programmers.
The A29160 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
A29160 has a second toggle bit, I/O
2
, to indicate whether the
addressed sector is being selected for erase. The A29160
also offers the ability to program in the Erase Suspend mode.
The standard A29160 offers access times of 55 and 70,
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 A29160 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.
