Features  
Description  
• Low power CMOS technology  
The Microchip Technology Inc. 93XX46A/B/C devices  
are 1K bit low voltage serial Electrically Erasable  
PROMs (EEPROM). Word-selectable devices such as  
the 93AA46C, 93LC46C or 93C46C are dependent  
upon external logic levels driving the ORG pin to set  
word size. For dedicated 8-bit communication, the  
93AA46A, 93LC46A or 93C46A devices are available,  
while the 93AA46B, 93LC46B and 93C46B devices  
provide dedicated 16-bit communication. Advanced  
CMOS technology makes these devices ideal for low  
power, non-volatile memory applications. The entire  
93XX Series is available in standard packages includ-  
ing 8-lead PDIP and SOIC, and advanced packaging  
including 8-lead MSOP, 6-lead SOT-23, and 8-lead  
TSSOP. Pb-free (Pure Matte Sn) finish is also  
available.

2.2  
Data In/Data Out (DI/DO)  
2.0  
FUNCTIONAL DESCRIPTION  
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. In order  
to limit this current, a resistor should be connected  
between DI and DO.  
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  
normally 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. DO will enter the HIGH-Z  
state on the falling edge of CS.  
2.3  
Data Protection  
All modes of operation are inhibited when VCC is below  
a typical voltage of 1.5V for '93AA' and '93LC' devices  
or 3.8V for '93C' devices.  
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.  
The EWEN and EWDS commands give additional  
protection against accidentally programming during  
normal operation.  
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  
operation (READ, WRITE, ERASE, EWEN, EWDS,  
ERAL, or WRAL). As soon as CS is HIGH, the device  
is no longer in Standby mode.  
Note: For added protection, an EWDS command  
should be performed after every write  
operation.  
After power-up, the device is automatically in the  
EWDS mode. Therefore, an EWENinstruction must be  
performed before the initial ERASEor WRITEinstruction  
can be executed.  
An instruction following a START condition will only be  
executed if the required opcode, address and data bits  
for any particular instruction are clocked in.

ERASE  
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 ERASEinstruction forces all data bits of the speci-  
fied 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 program-  
ming cycle, except on ‘93C’ devices where the rising  
edge of CLK before the last address bit initiates the  
write cycle.

ERASE ALL (ERAL)  
The Erase All (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, except on  
‘93C’ devices where the rising edge of CLK before the  
last data bit initiates the write cycle. Clocking of the  
CLK pin is not necessary after the device has entered  
the ERAL cycle.  
The DO pin indicates the READY/BUSY status of the  
device, if CS is brought high after a minimum of 250 ns  
low (TCSL).  
VCC must be 4.5V for proper operation of ERAL.

ERASE/WRITE DISABLE AND ENABLE (EWDS/EWEN)  
The 93XX46A/B/C powers up in the ERASE/WRITE  
Disable (EWDS) state. All Programming modes must be  
preceded by an ERASE/WRITE Enable (EWEN) instruc-  
tion. Once the EWENinstruction is executed, program-  
ming remains enabled until an EWDS instruction is  
executed or Vcc is removed from the device. To protect  
against accidental data disturbance, the EWDSinstruc-  
tion can be used to disable all ERASE/WRITE  
functions and should follow all programming opera-  
tions. Execution of a READinstruction is independent of  
both the EWENand EWDSinstructions.

READ  
The READ instruction outputs the serial data of the  
addressed memory location on the DO pin. A dummy  
zero bit precedes the 8-bit (If ORG pin is low or A-Version  
devices) or 16-bit (If ORG pin is high or B-version  
devices) output string. The output data bits will toggle on  
the rising edge of the CLK and are stable after the spec-  
ified 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.

WRITE  
The WRITEinstruction is followed by 8 bits (If ORG is  
low or A-version devices) or 16 bits (If ORG pin is high  
or B-version devices) of data which are written into the  
specified address. For 93AA46A/B/C and 93LC46A/B/C  
devices, after the last data bit is clocked into DI, the  
falling edge of CS initiates the self-timed auto-erase and  
programming cycle. For 93C46A/B/C devices, the self-  
timed auto-erase and programming cycle is initiated by  
the rising edge of CLK on the last data bit.  
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 written  
with the data specified and the device is ready for  
another instruction.

WRITE ALL (WRAL)  
The Write All (WRAL) instruction will write the entire  
memory array with the data specified in the command.  
For 93AA46A/B/C and 93LC46A/B/C devices, after the  
last data bit is clocked into DI, the falling edge of CS  
initiates the self-timed auto-erase and programming  
cycle. For 93C46A/B/C devices, the self-timed auto-  
erase and programming cycle is initiated by the rising  
edge of CLK on the last data bit. Clocking of the CLK  
pin is not necessary after the device has entered the  
WRAL cycle. The WRAL command does include an  
automatic ERAL cycle for the device. Therefore, the  
WRALinstruction does not require an ERALinstruction  
but the chip must be in the EWEN status.  
The DO pin indicates the READY/BUSY status of the  
device if CS is brought high after a minimum of 250 ns  
low (TCSL).  
VCC must be 4.5V for proper operation of WRAL.

CHIP SELECT (CS)  
3.3  
DATA IN (DI)  
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 in progress will be  
completed, regardless of the Chip Select (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 In (DI) is used to clock in a START bit, opcode,  
address and data synchronously with the CLK input.  
3.4  
DATA OUT (DO)  
Data Out (DO) is used in the READ mode to output  
data synchronously with the CLK input (TPD after the  
positive edge of CLK).  
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.  
This pin also provides READY/BUSY status informa-  
tion during ERASE and WRITE cycles. READY/BUSY  
status information 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.  
3.2  
SERIAL CLOCK (CLK)  
The Serial Clock is used to synchronize the communi-  
cation between a master device and the 93XX series  
device. Opcodes, 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.  
The status signal is not available on DO, if CS is held  
low during the entire ERASE or WRITE cycle. In this  
case, DO is in the HIGH-Z mode. If status is checked  
after the ERASE/WRITE cycle, the data line will be high  
to indicate the device is ready.  
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.  
3.5  
ORGANIZATION (ORG)  
When the ORG pin is connected to VCC or Logic HI, the  
(x16) memory organization is selected. When the ORG  
pin is tied to VSS or Logic LO, the (x8) memory  
organization is selected. For proper operation, ORG  
must be tied to a valid logic level.  
CLK is a “Don't Care” if CS is low (device deselected).  
If CS is high, but the START condition has not been  
detected (DI = 0), any number of clock cycles can be  
received by the device without changing its status (i.e.,  
waiting for a START condition).  
93XX46A devices are always x8 organization and  
93XX46B devices are always x16 organization.  
CLK cycles are not required during the self-timed  
WRITE (i.e., auto ERASE/WRITE) cycle.  
After detection of a START condition the specified  
number of clock cycles (respectively low to high transi-  
tions 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. CLK and DI  
then become don't care inputs waiting for a new START  
condition to be detected.

NOTES:  
DS21749B-page22  
2003 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 intended through suggestion only  
and may be superseded by updates. It is your responsibility to  
ensure that your application meets with your specifications. No  
representation or warranty is given and no liability is assumed by  
Microchip Technology Incorporated with respect to the accuracy  
or use of such information, or infringement of patents or other
