A29010B Series
Absolute Maximum Ratings*
Ambient Operating Temperature ..……………. -55°C to +125°C
Storage Temperature …………………………... -65°C to +125°C
Ground to VCC …………………………………….. -2.0V to 6.5V
Output Voltage (Note 1) …………………………… -2.0V to 6.5V
A9 & OE (Note 2) …………………………………. -2.0V to 11.5V
All other pins (Note 1)……………………………….. -2.0V to 6.5V
Output Short Circuit Current (Note 3) ……………………. 200mA
Notes:
1. Minimum DC voltage on input or I/O pins is -0.5V. During
voltage transitions, inputs may undershoot VSS to -2.0V for
periods of up to 20ns. Maximum DC voltage on output and
I/O pins is VCC +0.5V. During voltage transitions, outputs
may overshoot to VCC +1.5V for periods up to 20ns.
2. Minimum DC input voltage on A9 pins is -0.5V. During
voltage transitions, A9 and OE may overshoot VSS to -2.0V
for periods of up to 20ns. Maximum DC input voltage on A9
and OE is +11.5V which may overshoot to 12.5V for
periods up to 20ns.
3. No more than one output is shorted at a time. Duration of
the short circuit should not be greater than one second.
*Comments
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.
Operating Ranges
Commercial Devices
Ambient Temperature (TA) ………………………… 0°C to +70°C
Extended Range Devices
Ambient Temperature (TA) ……………………… -40°C to +85°C
VCC Supply Voltages
VCC for ± 10% devices …………………………. +4.5V to +5.5V
Operating ranges define those limits between which the
functionally of the device is guaranteed.
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.

Legend:
X = Don't care
RA = Address of the memory location to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE or CE pulse, whichever
happens later.
PD = Data to be programmed at location PA. Data latches on the rising edge of WE or CE pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits A16 - A15 select a unique sector.
Note:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Except when reading array or autoselect data, all bus cycles are write operation.
4. Address bits A16 - A12 are don't cares for unlock and command cycles, unless SA or PA required.
5. No unlock or command cycles required when reading array data.
6. The Reset command is required to return to reading array data when device is in the autoselect mode, or if I/O5 goes high (while
the device is providing status data).
7. The fourth cycle of the autoselect command sequence is a read cycle.
8. The data is 00h for an unprotected sector and 01h for a protected sector. See "Autoselect Command Sequence" for more
information.
9. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode.
10. The Erase Resume command is valid only during the Erase Suspend mode.
11. The time between each command cycle has to be less than 50μs
