General Description
The A29L320A is a 32Mbit, 3.3 volt-only Flash memory
organized as 2,097,152 words of 16 bits or 4,194,304 bytes
of 8 bits each. The 8 bits of data appear on I/O
bits of data appear on I/O
48-ball TFBGA and 48-Pin TSOP packages. This device is
designed to be programmed in-system with the standard
system 3.3 volt VCC supply. Additional 12.0 volt VPP is not
required for in-system write or erase operations. However,
the A29L320A can also be programmed in standard EPROM
programmers.
The A29L320A has the first toggle bit, I/O
whether an Embedded Program or Erase is in progress, or it
is in the Erase Suspend. Besides the I/O
A29L320A has a second toggle bit, I/O
the addressed sector is being selected for erase. The
A29L320A also offers the ability to program in the Erase

Suspend mode. The standard A29L320A offers access times
of 70,80,90 and 120ns, allowing high-speed microprocessors
to operate without wait states. To eliminate bus contention
the device has separate chip enable (
( WE ) and output enable (
The device requires only a single 3.3 volt power supply for
both read and write functions. Internally generated and
regulated voltages are provided for the program and erase
operations.
The A29L320A 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
