• Description: 1k/2k/4k-bit Spi Serial Eeprom
• Manufacturer: Catalyst Semiconductor

a 16-bit data field is also required following the 8-bit
address field.
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.

Upon receiving a READ command and address (clocked
into the DI pin), the DO pin will output data one t
the falling edge of the 16th clock (the last bit of the
address field). The READ operation is not affected by
the RESET input.
After receiving a WRITE op code, address and data, the
device goes into the AUTO-Clear cycle and then the
