The CAT93C86 is a 16K-bit Serial EEPROM memory
device which is configured as either registers of 16
bits (ORG pin at VCC) or 8 bits (ORG pin at GND).
Each register can be written (or read) serially by using
the DI (or DO) pin. The CAT93C86 is manufactured
using Catalyst’s advanced CMOS EEPROM floating
gate technology. The device is designed to endure
1,000,000 program/erase cycles and has a data
retention of 100 years. The device is available in 8-pin
DIP, 8-pin SOIC and 8-pad TDFN packages.

Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
(2) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20ns. Maximum DC
voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20ns.
(3) Output shorted for no more than one second. No more than one output shorted at a time.
(4) These parameters are tested initially and after a design or process change that affects the parameter.
(5) Latch-up protection is provided for stresses up to 100 mA pn address and data pins from –1V to VCC +1V.

DEVICE OPERATION
The CAT93C86 is a 16,384-bit nonvolatile memory
intended
for
use
with
industry
standard
microprocessors. The CAT93C86 can be organized
as either registers of 16 bits or 8 bits. When organized
as X16, seven 13-bit instructions control the reading,
writing and erase operations of the device. When
organized as X8, seven 14-bit instructions control the
reading, writing and erase operations of the device.
The CAT93C86 operates on a single power supply
and will generate on chip, the high voltage required
during any write operation.
is in Program Enabled mode. For Write Enable and
Write Disable instruction PE = don’t care.
Instructions, addresses, and write data are clocked
into the DI pin on the rising edge of the clock (SK).
The DO pin is normally in a high impedance state
except when reading data from the device, or when
checking the ready/busy status after a write operation.
After the initial data word has been shifted out and CS
remains asserted with the SK clock continuing to
toggle, the device will automatically increment to the
next address and shift out the next data word in a
sequential READ mode. As long as CS is
continuously asserted and SK continues to toggle, the
device will keep incrementing to the next address
automatically until it reaches to the end of the address
space, then loops back to address 0.
In the
sequential READ mode, only the initial data word is
preceeded by a dummy zero bit. All subsequent data
words will follow without a dummy zero bit.
Read
Upon receiving a READ command and an address
(clocked into the DI pin), the DO pin of the CAT93C86
will come out of the high impedance state and, after
sending an initial dummy zero bit, will begin shifting
out the data addressed (MSB first). The output data
bits will toggle on the rising edge of the SK clock and
are stable after the specified time delay (tPD0 or tPD1).
The ready/busy status can be determined after the
start of a write operation by selecting the device (CS
high) and polling the DO pin; DO low indicates that the
write operation is not completed, while DO high
indicates that the device is ready for the next
instruction. If necessary, the DO pin may be placed
back into a high impedance state during chip select by
shifting a dummy “1” into the DI pin. The DO pin will
enter the high impedance state on the falling edge of
the clock (SK). Placing the DO pin into the high
impedance state is recommended in applications
where the DI pin and the DO pin are to be tied
together to form a common DI/O pin.
Write
After receiving a WRITE command, address and the
data, the CS (Chip Select) pin must be deselected for
a minimum of tCSMIN. The falling edge of CS will start
the self clocking clear and data store cycle of the
memory location specified in the instruction. The
clocking of the SK pin is not necessary after the
device has entered the self clocking mode. The
ready/busy status of the CAT93C86 can be
determined by selecting the device and polling the DO
pin. Since this device features Auto-Clear before
write, it is NOT necessary to erase a memory location
before it is written into.
The format for all instructions sent to the device is a
logical “1” start bit, a 2-bit (or 4-bit) opcode, 10-bit
address (an additional bit when organized X8) and for
write operations a 16-bit data field (8-bit for X8
organizations).
Note: The Write, Erase, Write all and Erase all
instructions require PE=1. If PE is left floating, 93C86

CAT93C86 (Rev. C)
Erase
Upon receiving an ERASE command and address,
the CS (Chip Select) pin must be deasserted for a
minimum of tCSMIN. The falling edge of CS will start the
self clocking clear cycle of the selected memory
location. The clocking of the SK pin is not necessary
after the device has entered the self clocking mode.
The ready/busy status of the CAT93C86 can be
determined by selecting the device and polling the DO
pin. Once cleared, the content of a cleared location
returns to a logical “1” state.
Erase All
Upon receiving an ERAL command, the CS (Chip
Select) pin must be deselected for a minimum of
tCSMIN. The falling edge of CS will start the self clocking
clear cycle of all memory locations in the device. The
clocking of the SK pin is not necessary after the
device has entered the self clocking mode. The
ready/busy status of the CAT93C86 can be
determined by selecting the device and polling the DO
pin. Once cleared, the contents of all memory bits
return to a logical “1” state.
Erase/Write Enable and Disable
The CAT93C86 powers up in the write disable state.
Any writing after power-up or after an EWDS (write
disable) instruction must first be preceded by the
EWEN (write enable) instruction. Once the write
instruction is enabled, it will remain enabled until
power to the device is removed, or the EWDS
instruction is sent. The EWDS instruction can be used
to disable all CAT93C86 write and clear instructions,
and will prevent any accidental writing or clearing of
the device. Data can be read normally from the device
regardless of the write enable/disable status.
Write All
Upon receiving a WRAL command and data, the CS
(Chip Select) pin must be deselected for a minimum of
tCSMIN. The falling edge of CS will start the self clocking
data write to all memory locations in the device. The
clocking of the SK pin is not necessary after the
device has entered the self clocking mode. The
ready/busy status of the CAT93C86 can be
determined by selecting the device and polling the DO
pin. It is not necessary for all memory locations to be
cleared before the WRAL command is executed.
