CAT64LC10/20/40
Doc. No. 1021, Rev. A
DEVICE 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.
There are four 16-bit instructions: READ, WRITE, EWEN,
and EWDS. The CAT64LC10/20/40 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 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 format for all instructions sent to this device includes
a 4-bit start sequence, 1010, a 4-bit op code and an 8-
bit address field or dummy bits. For a WRITE operation,
