DESCRIPTION
CMOS EEPROM floating gate technology. The devices
aredesignedtoendure1,000,000program/erasecycles
and have a data retention of 100 years. The devices are
available in 8-pin DIP, 8-pin SOIC, 8-pin TSSOP and 8-
pad TDFN packages.
The CAT93C46/56/57/66/86 are 1K/2K/2K/4K/16K-bit
Serial EEPROM memory devices which are configured
as either registers of 16 bits (ORG pin at VCC) or 8 bits
(ORGpinatGND). Eachregistercanbewritten(orread)
serially by using the DI (or DO) pin. The CAT93C46/56/
57/66/86 are manufactured using Catalyst’s advanced

DEVICE OPERATION
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.
The CAT93C46/56(57)66/86 is a 1024/2048/4096/
16,384-bit nonvolatile memory intended for use with
industrystandardmicroprocessors. TheCAT93C46/56/
57/66/86 can be organized as either registers of 16 bits
or 8 bits. When organized as X16, seven 9-bit instruc-
tions for 93C46; seven 10-bit instructions for 93C57;
seven 11-bit instructions for 93C56 and 93C66; seven
13-bitinstructionsfor93C86;controlthereading, writing
and erase operations of the device. When organized as
X8, seven 10-bit instructions for 93C46; seven 11-bit
instructions for 93C57; seven 12-bit instructions for
93C56 and 93C66: seven 14-bit instructions for 93C86;
control the reading, writing and erase operations of the
device.TheCAT93C46/56/57/66/86operatesonasingle
power supply and will generate on chip, the high voltage
required during any write operation.
The ready/busy status can be determined after the start
ofawriteoperationbyselectingthedevice(CShigh)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
DIpin. TheDOpinwillenterthehighimpedancestateon
the falling edge of the clock (SK). Placing the DO pin into
the high impedance state is recommended in applica-
tions where the DI pin and the DO pin are to be tied
together to form a common DI/O pin.
Instructions, addresses, and write data are clocked into

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.
Note: This note is applicable only to 93C86. The Write,
Erase, Write all and Erase all instructions require PE=1.
If PE is left floating, 93C86 is in Program Enabled mode.

Write
Read
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
CAT93C46/56/57/66/86canbedeterminedbyselecting
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.
Upon receiving a READ command and an address
(clocked into the DI pin), the DO pin of the CAT93C46/
56/57/66/86 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

For the CAT93C56/57/66/86, after the initial data word

The CAT93C46/56/57/66/86 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
CAT93C46/56/57/66/86 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.
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
hasenteredtheselfclockingmode. (Note1.) Theready/
busy status of the CAT93C46/56/57/66/86 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.
