The Microchip Technology Inc. 93XX86A/B/C devices
are 16K bit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93XX86C are dependent upon external logic
levels driving the ORG pin to set word size. The
93XX86A devices provide dedicated 8-bit memory
organization, while the 93XX86B devices provide
dedicated 16-bit memory organization. A Program
Enable (PE) pin allows the user to write-protect the
entire memory array. Advanced CMOS technology
makes these devices ideal for low-power, nonvolatile
memory applications. The entire 93XX Series is
available in standard packages including 8-lead PDIP
and SOIC, and advanced packaging including 8-lead
MSOP, 6-lead SOT-23, 8-lead 2x3 DFN/TDFN and 8lead TSSOP. All packages are Pb-free (Matte Tin)
finish.

FUNCTIONAL DESCRIPTION
When the ORG pin (93XX86C) 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.
2.1
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.
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.
2.3
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.
The EWEN and EWDS commands give additional
protection against accidentally programming during
normal operation.
Note:
For added protection, an EWDS command
should be performed after every write
operation and an external 10 k pulldown protection resistor should be added
to the CS pin.
After power-up the device is automatically in the EWDS
mode. Therefore, an EWEN instruction must be
performed before the initial ERASE or WRITE instruction
can be executed.
Note:
To prevent accidental writes to the array in
the 93XX86C devices, set the PE pin to a
logic low.

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.
Note:
Data Protection
Address
Counter
When preparing to transmit an instruction,
either the CLK or DI signal levels must be
at a logic low as CS is toggled active high.

2.2
Data In/Data Out (DI/DO)
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 the
driver, the higher the voltage at the Data Out pin. In
order to limit this current, a resistor should be
connected between DI and DO.

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 programming
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 instruction forces all data bits of the
specified address to the logical ‘1’ state. The rising
edge of CLK before the last address bit initiates the
write cycle.
Note:
FIGURE 2-1:
After the Erase cycle is complete, issuing
a Start bit and then taking CS low will clear
the Ready/Busy status from DO.

Erase All (ERAL)
The DO pin indicates the Ready/Busy status of the
device, if CS is brought high after a minimum of 250 ns
low (TCSL).
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. 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.

Note:
After the ERAL command is complete,
issuing a Start bit and then taking CS low

Erase/Write Disable and Enable
(EWDS/EWEN)
Once the EWEN instruction is executed, programming
remains enabled until an EWDS instruction is executed
or VCC is removed from the device.
The 93XX86A/B/C powers up in the Erase/Write
Disable (EWDS) state. All programming modes must be
preceded by an Erase/Write Enable (EWEN) instruction.
FIGURE 2-3:
To protect against accidental data disturbance, 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.

Read
The output data bits will toggle on the rising edge of the

Sequential read is possible when CS is held high. The
memory data will automatically cycle to the next register
and output sequentially.
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.

Write
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 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 instruction 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. The self-timed auto-erase and
programming cycle is initiated by the rising edge of CLK
on the last data bit.
FIGURE 2-6:
Note:
The write sequence requires a logic high
signal on the PE pin prior to the rising
edge of the last data bit.

Write All (WRAL)
The DO pin indicates the Ready/Busy status of the
device if CS is brought high after a minimum of 250 ns
low (TCSL).
The Write All (WRAL) instruction will write the entire
memory array with the data specified in the command.
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 WRAL instruction does not
require an ERAL instruction, but the chip must be in the
EWEN status.
Note:
The write sequence requires a logic high
signal on the PE pin prior to the rising
edge of the last data bit.
Note:
After the Write All cycle is complete,
issuing a Start bit and then taking CS low
will clear the Ready/Busy status from DO.

Note 1:
3.1
The exposed pad on the DFN/TDFN package may be connected to Vss or left floating.
Chip Select (CS)
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.
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.
3.2
Serial Clock (CLK)
The Serial Clock is used to synchronize the communication 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.
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 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).
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 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. CLK and DI
then become “don't care” inputs waiting for a new Start
condition to be detected.

3.3
Data In (DI)
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).
This pin also provides Ready/Busy status information
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.
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.
Note:
3.5
After a programming cycle is complete,
issuing a Start bit and then taking CS low
will clear the Ready/Busy status from DO.
Organization (ORG)
When the ORG pin is connected to VCC or logic high,
the (x16) memory organization is selected. When the
ORG pin is tied to VSS or logic low, the (x8) memory
organization is selected. For proper operation, ORG
must be tied to a valid logic level.
93XX86A devices are always (x8) organization and
93XX86B devices are always (x16) organization.

3.6
Program Enable (PE)
This pin allows the user to enable or disable the ability
to write data to the memory array. If the PE pin is tied
to VCC, the device can be programmed. If the PE pin is
tied to VSS, programming will be inhibited. This pin
cannot be floated, it must be tied to VCC or VSS. PE is
not available on 93XX86A or 93XX86B. On those
devices, programming is always enabled.
