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.
• 64-Byte Page Write Buffer
• Hardware Write-Protect
• ESD Protection > 4,000V
Note 1: 24XX128 is used in this document as a
generic part number for the 24AA128/
24LC128/24FC128 devices.
• More than 1 Million Erase/Write Cycles
• Data Retention > 200 years
• Factory Programming Available
• RoHS Compliant
• Temperature Ranges:
- Industrial (I):
- Extended (E)
-40C to +85C
-40C to +125C
• Automotive AEC-Q100 Qualified
