DESCRIPTION
TheCAT64LC10/20/40isa1K/2K/4K-bitSerialE2PROM
which is configured as 64/128/256 registers by 16 bits.
Each register can be written (or read) serially by using
the DI (or DO) pin. The CAT64LC10/20/40 is manufac-
tured using Catalyst’s advanced CMOS E2PROM float-
ing gate technology. It 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 or SOIC
packages.

DEVICE OPERATION
and data to be written are clocked into the DI pin on the
rising 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 CAT64LC10/20/40 is a 1K/2K/4K-bit nonvolatile
memory intended for use with all standard controllers.
The CAT64LC10/20/40 is organized in a 64/128/256 x
16 format. All instructions are based on an 8-bit format.

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 CAT64LC10/20/40 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

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
occurs after the BUSY period, new data will have been

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 CAT64LC10/20/40 powers up in the erase/write
disabledstate.Afterpower-uporwhilethedeviceisinan
erase/write disabled state, any write operation must be
preceded by an execution of the EWEN instruction.
Once enabled, the device will stay enabled until an
EWDShasbeenexecutedorapower-downhasoccured.
The EWDS is used to prevent any inadvertent over-
writing of the data. The EWEN and EWDS instructions
have no affect on the READ operation and are not
affected by the 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.
