The EWEN and EWDS commands give additional
protection against accidentally programming during
normal operation.
2.0
FUNCTIONAL DESCRIPTION
When the ORG pin is connected to VCC, the (x16)
organization is selected. When it is connected to
ground, the (x8) organization is selected. Instructions,
addresses and write data are clocked into the DI pin on
the rising edge of the clock (CLK). The DO pin is nor-
mally held in a high-Z state except when reading data
from the device, or when checking the Ready/Busy
status during a programming operation. The Ready/
Busy status can be verified during an erase/write
operation by polling the DO pin; DO low indicates that
programming is still in progress, while DO high
indicates the device is ready. The DO will enter the
high-Z state on the falling edge of the CS.
After power-up, the device is automatically in the
EWDS mode. Therefore, an EWEN instruction must be
performed before any ERASE or WRITE instruction can
be executed.
2.4
Read
The READ instruction outputs the serial data of the
addressed memory location on the DO pin. A dummy
zero bit precedes the 16-bit (x16 organization) or 8 bit
(x8 organization) output string. The output data bits will
toggle on the rising edge of the CLK and are stable
after the specified time delay (TPD). Sequential read is
possible when CS is held high. The memory data will
automatically cycle to the next register and output
sequentially.
2.1
Start Condition
The Start bit is detected by the device if CS and DI are
both high with respect to the positive edge of CLK for
the first time.
2.5
Erase/Write Enable and Disable
Before a Start condition is detected, CS, CLK and DI
may change in any combination (except to that of a
Start condition), without resulting in any device opera-
tion (read, write, erase, EWEN, EWDS, ERAL, and
WRAL). As soon as CS is high, the device is no longer
in the Standby mode.
(EWEN, EWDS)
The 93AA46/56/66 power up in the Erase/Write Disable
(EWDS) state. All programming modes must be
preceded by an Erase/Write Enable (EWEN) instruction.
Once the EWEN instruction is executed, programming
remains enabled until an EWDS instruction is executed or
VCC is removed from the device. To protect against
accidental data disturb, the EWDS instruction can be used
to disable all erase/write functions and should follow all
programming operations. Execution of a READ instruction
is independent of both the EWEN and EWDS instructions.
An instruction following a Start condition will only be
executed if the required amount of opcode, address
and data bits for any particular instruction is clocked in.
After execution of an instruction (i.e., clock in or out of
the last required address or data bit) CLK and DI
become “don't care” bits until a new Start condition is
detected.
2.6
Erase
2.2
DI/DO
The ERASE instruction forces all data bits of the
specified address to the logical “1” state. CS is brought
low following the loading of the last address bit. This
falling edge of the CS pin initiates the self-timed
programming cycle.
It is possible to connect the Data In and Data Out pins
together. However, with this configuration it is possible
for a “bus conflict” to occur during the “dummy zero”
that precedes the read operation, if A0 is a logic high
level. Under such a condition the voltage level seen at
Data Out is undefined and will depend upon the relative
impedances of Data Out and the signal source driving
A0. The higher the current sourcing capability of A0,
the higher the voltage at the Data Out pin.
The DO pin indicates the Ready/Busy status of the
device if CS is brought high after a minimum of 250 ns
low (TCSL). DO at logical “0” indicates that program-
ming is still in progress. DO at logical “1” indicates that
the register at the specified address has been erased
and the device is ready for another instruction.
The erase cycle takes 4 ms per word typical.
2.3
Data Protection
During power-up, all programming modes of operation
are inhibited until VCC has reached a level greater than
1.4V. During power-down, the source data protection
circuitry acts to inhibit all programming modes when
VCC has fallen below 1.4V at nominal conditions.
DS20067K-page 6
1998-2012 Microchip Technology Inc.
93AA46/56/66
The DO pin indicates the Ready/Busy status of the
device if CS is brought high after a minimum of 250 ns
low (TCSL) and before the entire write cycle is complete.
2.7
Write
The WRITE instruction is followed by 16 bits (or by 8
bits) of data which are written into the specified
address. After the last data bit is put on the DI pin,
CS must be brought low before the next rising edge
of the CLK clock. This falling edge of CS initiates the
self-timed auto-erase and programming cycle.
The ERAL cycle takes (8 ms typical).
2.9
Write All (WRAL)
The WRAL instruction will write the entire memory array
with the data specified in the command. The WRAL
cycle is completely self-timed and commences at the
falling edge of the CS. Clocking of the CLK pin is not
necessary after the device has entered the Self Clock-
ing mode. The WRAL command does include an auto-
matic ERAL cycle for the device. Therefore, the WRAL
instruction does not require an ERAL instruction but the
chip must be in the EWEN status. The WRAL instruction
is ensured at 5V 10%.
The DO pin indicates the Ready/Busy status of the
device if CS is brought high after a minimum of 250 ns
low (TCSL) and before the entire write cycle is complete.
DO at logical “0” indicates that programming is still in
progress. DO at logical “1” indicates that the register at
the specified address has been written with the data
specified and the device is ready for another
instruction.
The write cycle takes 4 ms per word typical.
The DO pin indicates the Ready/Busy status of the
device if CS is brought high after a minimum of 250 ns
low (TCSL).
2.8
Erase All (ERAL)
The ERAL instruction will erase the entire memory array
to the logical “1” state. The ERAL cycle is identical to
the erase cycle except for the different opcode. The
ERAL cycle is completely self-timed and commences
at the falling edge of the CS. Clocking of the CLK pin is
not necessary after the device has entered the Self
Clocking mode. The ERAL instruction is ensured at 5V
10%.
The WRAL cycle takes 16 ms typical.

After detection of a Start condition the specified number
of clock cycles (respectively low-to-high transitions of
CLK) must be provided. These clock cycles are
required to clock in all required opcode, address and
data bits before an instruction is executed (see instruc-
tion set truth table). CLK and DI then become “don't
care” inputs waiting for a new Start condition to be
detected.

3.1
Chip Select (CS)
3.4
Data Out (DO)
A high level selects the device. A low level deselects
the device and forces it into Standby mode. However, a
programming cycle which is already initiated and/or in
progress will be completed, regardless of the CS input
signal. If CS is brought low during a program cycle, the
device will go into Standby mode as soon as the
programming cycle is completed.
Data Out is used in the Read mode to output data
synchronously with the CLK input (TPD after the
positive edge of CLK).
This pin also provides Ready/Busy status information
during erase and write cycles. Ready/Busy status infor-
mation is available on the DO pin if CS is brought high
after being low for minimum chip select low time (TCSL)
and an erase or write operation has been initiated.
CS must be low for 250 ns minimum (TCSL) between
consecutive instructions. If CS is low, the internal
control logic is held in a Reset status.
The status signal is not available on DO, if CS is held
low or high during the entire write or erase cycle. In all
other cases DO is in the High-Z mode. If status is
checked after the write/erase cycle, a pull-up resistor
on DO is required to read the Ready signal.
3.2
Serial Clock (CLK)
The Serial Clock is used to synchronize the communi-
cation between a master device and the 93AAXX.
Opcode, address, and data bits are clocked in on the
positive edge of CLK. Data bits are also clocked out on
the positive edge of CLK.
3.5
Organization (ORG)
When ORG is connected to VCC, the (x16) memory
organization is selected. When ORG is tied to VSS, the
(x8) memory organization is selected. ORG can only be
floated for clock speeds of 1MHz or less for the (x16)
memory organization. For clock speeds greater than 1
MHz, ORG must be tied to VCC or VSS.
CLK can be stopped anywhere in the transmission
sequence (at high or low level) and can be continued
anytime with respect to clock high time (TCKH) and
clock low time (TCKL). This gives the controlling master
freedom in preparing opcode, address and data.
CLK is a “don't care” if CS is low (device deselected). If
CS is high, but Start condition has not been detected,
any number of clock cycles can be received by the
device without changing its status (i.e., waiting for Start
condition).
CLK cycles are not required during the self-timed write
(i.e., auto erase/write) cycle.

NOTES:
DS20067K-page 20
1998-2012 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
