DEVICE DESCRIPTION
The CAT24C03/CAT24C05 is a 2-kb/4-kb CMOS Serial
EEPROM device organized internally as 16/32 pages
of 16 bytes each, for a total of 256x8/512x8 bits. These
devices support both Standard (100kHz) as well as Fast
(400kHz) I2C protocol.
Data is written by providing a starting address, then
loading 1 to 16 contiguous bytes into a Page Write
Buffer, and then writing all data to non-volatile memory
in one internal write cycle. Data is read by providing a
starting address and then shifting out data serially while
automatically incrementing the internal address count.
Write operations can be inhibited for upper half of memory
by taking the WP pin High.
External address pins make it possible to address
up to eight CAT24C03 or four CAT24C05 devices on the
same bus.

Note:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this speci-
fication is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
(2) The DC input voltage on any pin should not be lower than -0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than -1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.
(3) These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC-Q100
and JEDEC test methods.
(4) Page Mode, VCC = 5 V, 25°C
(5) When not driven, the WP pin is pulled down to GND internally. For improved noise immunity, the internal pull-down is relatively strong;
therefore the external driver must be able to supply the pull-down current when attempting to drive the input HIGH. To conserve power,
as the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x VCC), the strong pull-down reverts to a weak current source.
