Description
The Microchip Technology Inc. 24XX128
(1)
is a 16K x
8 (128 Kbit) Serial Electrically Erasable PROM
(EEPROM), capable of operation across a broad volt-
age range (1.7V to 5.5V). It has been developed for
advanced, low-power applications such as personal
communications or data acquisition. This device also
has a page write capability of up to 64 bytes of data.
This device is capable of both random and sequential
reads up to the 128K boundary. Functional address
lines allow up to eight devices on the same bus, for up
to 1 Mbit address space.
Note 1:
24XX128 is used in this document as a
generic part number for the 24AA128/
24LC128/24FC128 devices.

As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.
3:
The combined T
SP
and V
HYS
specifications are due to new Schmitt Trigger inputs, which provide improved
noise spike suppression. This eliminates the need for a T
