General Description
The A29L800C 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/O0 - I/O7; the 16 bits of
data appear on I/O0~I/O15. The A29L800C is offered in 48-ball
TFBGA 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 A29L800C can
also be programmed in standard EPROM programmers.
The A29L800C 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
A29L800C has a second toggle bit, I/O2, to indicate whether
the addressed sector is being selected for erase. The
A29L800C also offers the ability to program in the Erase
Suspend mode. The standard A29L800C offers access times
of 70ns, 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.
- Embedded Program algorithm automatically writes and
verifies data at specified addresses
„ Minimum 100,000 program/erase cycles per sector
„ 20-year data retention 125°C
- Reliable operation for the life of the system
„ Compatible with JEDEC-standards
- Pinout and software compatible with single-power-supply
Flash memory standard
- Superior inadvertent write protection
„ Data Polling and toggle bits
- Provides a software method of detecting completion of
program or erase operations
„ Ready / BUSY pin (RY / BY )
- Provides a hardware method of detecting completion of
program or erase operations
„ 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
„ Hardware reset pin (RESET )
- Hardware method to reset the device to reading array data
„ Package options
- 48-pin TSOP (I) or 48-ball TFBGA
- All Pb-free (Lead-free) products are RoHS2.0 compliant
The A29L800C 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. 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/O7 ( Data Polling) and I/O6 (toggle) status bits.
