FEATURES
DESCRIPTION
„ High speed operation: 2MHz
The CAT93C56/57 is a 2-Kb CMOS Serial EEPROM
device which is organized as either 128 registers of 16
bits (ORG pin at VCC) or 256 registers of 8 bits (ORG pin
at GND). Each register can be written (or read) serially
by using the DI (or DO) pin. The CAT93C56/57 features
sequential read and self-timed internal write with autoclear. On-chip Power-On Reset circuitry protects the
internal logic against powering up in the wrong state.

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 DC input voltage on any pin should not be lower than -0.5V or higher than VCC + 0.5V. During transitions, the voltage on any pin may
undershoot to no less than -1.5V or overshoot to no more than VCC + 1.5V, for periods of less than 20 ns.
(3) These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC-Q100
and JEDEC test methods.

DEVICE OPERATION
The CAT93C56/57 is a 2048-bit nonvolatile memory
intended for use with industry standard microprocessors. The CAT93C56/57 can be organized as
either registers of 16 bits or 8 bits. When organized as
X16, seven 10-bit instructions for 93C57 or seven 11bit instructions for 93C56 control the reading, writing
and erase operations of the device. When organized
as X8, seven 11-bit instructions for 93C57 or seven
12-bit instructions for 93C56 control the reading,
writing and erase operations of the device. The
CAT93C56/57 operates on a single power supply and
will generate on chip, the high voltage required during
any write operation.
except when reading data from the device, or when
checking the ready/busy status after a write operation.
The serial communication protocol follows the timing
shown in Figure 1.
The ready/busy status can be determined after the start
of internal write cycle 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 rising 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.
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

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. The READ
instruction timing is illustrated in Figure 2.
Read
Upon receiving a READ command and an address
(clocked into the DI pin), the DO pin of the
CAT93C56/57 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).
Erase/Write Enable and Disable
The CAT93C56/57 powers up in the write disable state.
Any writing after power-up or after an EWDS (erase/write
disable) instruction must first be preceded by the EWEN
(erase/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
CAT93C56/57 write and erase 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. The EWEN and EWDS
instructions timing is shown in Figure 3.
For the CAT93C56/57, 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

Write
After receiving a WRITE command (Figure 4), 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 CAT93C56/57 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.
Erase
Upon receiving an ERASE command and address, the
CS (Chip Select) pin must be deasserted for a
minimum of tCSMIN (Figure 5). The falling edge of CS will
start the self clocking clear cycle of the selected
memory location. The clocking of the SaK pin is not
necessary after the device has entered the self clocking
mode. The ready/busy status of the CAT93C56/57 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 (Figure 6), 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 CAT93C56/57 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.

Upon receiving a WRAL command and data, the CS
(Chip Select) pin must be deselected for a minimum of

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 CAT93C56/57 can be
