Preliminary
Features
n Single power supply operation
- Full voltage range: 2.7 to 3.6 volt read and write
operations for battery-powered applications
- Regulated voltage range: 3.0 to 3.6 volt read and write
operations for compatibility with high performance 3.3
volt microprocessors
n Access times:
- 70/90 (max.)
n Current:
- 4 mA typical active read current
- 20 mA typical program/erase current
- 200 nA typical CMOS standby
- 200 nA Automatic Sleep Mode current
n Flexible sector architecture
- 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX7 sectors
- Any combination of sectors can be erased
- Supports full chip erase
- Sector protection:
A hardware method of protecting sectors to prevent
any inadvertent program or erase operations within
that sector. Temporary Sector Unprotect feature
allows code changes in previously locked sectors
n Unlock Bypass Program Command
- Reduces overall programming time when issuing
multiple program command sequence
n Top or bottom boot block configurations available
n 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
A29L004 Series
512K X 8 Bit CMOS 3.0 Volt-only,
Boot Sector Flash Memory
n Typical 100,000 program/erase cycles per sector
n 20-year data retention at 125°C
- Reliable operation for the life of the system
n Compatible with JEDEC-standards
- Pinout and software compatible with single-power-
supply Flash memory standard
- Superior inadvertent write protection
n Data Polling and toggle bits
- Provides a software method of detecting completion
of program or erase operations
n Ready / BUSY pin (RY / BY )
- Provides a hardware method of detecting completion
of program or erase operations (not available on 32-
pin PLCC & (s)TSOP packages)
n 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
n Hardware reset pin (RESET )
- Hardware method to reset the device to reading array
data (not available on 32 pin PLCC & (s)TSOP
packages)
n Package options
- 40-pin TSOP (forward type), 32-pin PLCC or (s)TSOP
(forward type)

Notes:
1. Minimum DC voltage on input or I/O pins is -0.5V. During
voltage transitions, input or I/O pins may undershoot
VSS to -2.0V for periods of up to 20ns. Maximum DC
voltage on input and I/O pins is VCC +0.5V. During
voltage transitions, input or I/O pins may overshoot to
VCC +2.0V for periods up to 20ns.
2. Minimum DC input voltage on A9, OE and RESET is -
0.5V. During voltage transitions, A9, OE and RESET
may overshoot VSS to -2.0V for periods of up to 20ns.
Maximum DC input voltage on A9 is +12.5V which may
overshoot to 14.0V for periods up to 20ns. (RESET is
N/A on 32-pin PLCC & (s)TSOP)
3. No more than one output is shorted at a time. Duration
of the short circuit should not be greater than one
second.
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device.
These are stress ratings only. Functional operation of
this device at these or any other conditions above
those indicated in the operational sections of these
specification is not implied or intended. Exposure to
the absolute maximum rating conditions for extended
periods may affect device reliability.

Device Bus Operations
This section describes the requirements and use of the
device bus operations, which are initiated through the
internal command register. The command register itself
does not occupy any addressable memory location. The
register is composed of latches that store the commands,
along with the address and data information needed to
execute the command. The contents of the register serve
as inputs to the internal state machine. The state machine
outputs dictate the function of the device. The appropriate
device bus operations table lists the inputs and control
levels required, and the resulting output. The following
subsections describe each of these operations in further
detail.
