edge of the SK clock. The DO pin is normally in a high
impedance state except when outputting data in a
READ operation or outputting RDY/BSY status when
polled during a WRITE operation.
The CAT64LC40 is a 4K-bit nonvolatile memory in-
tended for use with all standard controllers. The
CAT64LC40 is organized in a 256 x 16 format. All
instructions are based on an 8-bit format. There are four
16-bit instructions: READ, WRITE, EWEN, and EWDS.
The CAT64LC40 operates on a single power supply
ranging from 2.5V to 6.0V and it has an on-chip voltage
generator to provide the high voltage needed during a
programming operation. Instructions, addresses and
Theformatforallinstructionssenttothisdeviceincludes
a 4-bit start sequence, 1010, a 4-bit op code and an 8-
bit address field or dummy bits. For a WRITE operation,

a 16-bit data field is also required following the 8-bit
address field.
Read
UponreceivingaREADcommandandaddress(clocked
into the DI pin), the DO pin will output data one tPD after
the falling edge of the 16th clock (the last bit of the
address field). The READ operation is not affected by
the RESET input.
The CAT64LC40 requires an active LOW CS in order to
be selected. Each instruction must be preceded by a
HIGH-to-LOW transition of CS before the input of the 4-
bit start sequence. Prior to the 4-bit start sequence
(1010), the device will ignore inputs of all other logical
sequence.
Write
After receiving a WRITE op code, address and data, the
device goes into the AUTO-Clear cycle and then the

status (LOW) one tSV after the rising edge of the 32nd
clock (the last data bit) and will stay LOW until the write
cycle is complete. Then it will output a logical “1” until the
next WRITE cycle. The RDY/BSY output is not affected
by the input of CS.
the device is deselected. The rising edge of the first “1”
input on the DI pin will reset DO back to the high
impedance state again.
The WRITE operation can be halted anywhere in the
operation by the RESET input. If a RESET pulse occurs
during a WRITE operation, the device will abort the
operation and output a READY status.

NOTE: Data may be corrupted if a RESET occurs while
the device is BUSY. If the reset occurs before the BUSY
period, no writing will be initiated. However, if RESET

ERASE/WRITE ENABLE and DISABLE
The RESET pin, when set to HIGH, will reset or abort a
WRITEoperation.WhenRESETissettoHIGHwhilethe
WRITE instruction is being entered, the device will not
executetheWRITEinstructionandwillkeepDOinHigh-
Z condition.
The CAT64LC40 powers up in the erase/write disabled
state. After power-up or while the device is in an erase/
write disabled state, any write operation must be pre-
ceded by an execution of the EWEN instruction. Once
enabled, thedevicewillstayenableduntil anEWDShas
been executed or a power-down has occured. The
EWDS is used to prevent any inadvertent over-writing of
the data. The EWEN and EWDS instructions have no
affectontheREADoperationandarenotaffectedbythe
RESET input.
When RESET is set to HIGH, while the device is in a
clear/write cycle, the device will abort the operation and
will display READY status on the RDY/BSY pin and on
the DO pin if CS is low.
The RESET input affects only the WRITE and WRITE
ALL operations. It does not reset any other operations
such as READ, EWEN and EWDS.
