DEVICE OPERATION
The CAT93C46 is a 1024-bit nonvolatile memory in-
tended for use with industry standard microprocessors.
The CAT93C46 can be organized as either registers of
16 bits or 8 bits. When organized as X16, seven 9bit
instructionscontrolthereading,writinganderaoper-
tions of the device. When organized as X8, seven 10-bit
instructions control the reading, writing ad erase
operations of the device. The CAT93C6 operates on
a single power supply and will gon hip, the high
voltage required during any wration.
Thformt for all instructions sent to the device is a
ogicl"1"startbit, a2-bit(or4-bit)opcode, 6-bitaddress
(n additional bit when organized X8) and for write
operationsa16-bitdatafield(8-bitforX8organizations).
Read
Upon receiving a READ command and an address
(clockedintotheDIpin),theDOpinoftheCAT93C46will
come out of the high impedance state and, after sending
an initial dummy zero bit, will begin shifting out the data
addressed(MSBfirst). Theoutputdatabitswilltoggleon
the rising edge of the SK clock and are stable after the
specified time delay (tPD0 or tPD1).
Instructions, addressesand write data are clocked into
the DI pin on the rising edge of the clock (SK). The DO
pin is normally in a hih impedance state except when
readatfrom the device, or when checking the
y staus after a write operation.
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
CAT93C46 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.
Th/busy status can be determined after the start
ofawiteoperationbyselectingthedevice(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.

UponreceivinganERALcommand,theCS(ChipSelect)
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
CAT93C46 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 C

tCSMIN. The falling edge of CS will start the self clcking
data write to all memory locations in te dice. The
clocking of the SK pin is not nry afe device

selecting the device d polling he DO pin. It is not
necessary for all mlocations to be cleared before

TheCAT93C46powersupinthewritedisablestate. Any
writing after power-up or after an EWDS (write disable)
instruction must first be preceded by the EWEN (write
enable)instruction.Oncethewriteinstructionisenabled,
itwillremainenableduntilpowertothedeviceisremoved,
or the EWDS instruction is sent. The EWDS instruction
can be used to disable all CAT93C46 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.
Note:
(1) WitCATC46 Die revision H, after the last data bit has been
sampd, Chip Select (CS) must be brought Low before the
ext rig edge of the clock(SK) in order to start the slef-timed
hh voltage cycle. This is important because if the CS is
brought low before or after this specific frame window, the
addressed location will not be programmed or erased.
