CAT24C164
16 kb CMOS Serial
EEPROM, Cascadable
Description
The CAT24C164 is a 16 kb CMOS cascadable Serial EEPROM
device organized internally as 128 pages of 16 bytes each, for a total of
2048 x 8 bits. The device supports both the Standard (100 kHz) as well
as Fast (400 kHz) I
2
C 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
nonvolatile 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.
External address pins make it possible to address up to eight
CAT24C164 devices on the same bus.

Parameters Ratings Units
Storage Temperature –65 to +150 °C
Voltage on Any Pin with Respect to Ground (Note 1) –0.5 to +6.5 V
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V
CC
+ 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 V
CC
+ 1.5 V, for periods of less than 20 ns.

4. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECQ100
and JEDEC test methods.
5. When not driven, the WP pin is pulled down to GND internally. For improved noise immunity, the internal pulldown is relatively strong;
therefore the external driver must be able to supply the pulldown 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 V
CC
), the strong pulldown reverts to a weak current source.
