Description
The Microchip Technology Incorporated
24AA1026/24LC1026/24FC1026 (24XX1026*) is a
128K x 8 (1024 Kbit) Serial Electrically Erasable
PROM, capable of operation across a broad voltage
range (1.7V to 5.5V).
It has been developed for advanced, low-power
applications such as personal communications or data
acquisition. This device has both byte write and page
write capability of up to 128 bytes of data.
This device is capable of both random and sequential
reads. Reads may be sequential within address
boundaries 0000h to FFFFh and 10000h to 1FFFFh.
Functional address lines allow up to four devices on the
same data bus. This allows for up to 4 Mbits total
system EEPROM memory. This device is available in
the standard 8-pin PDIP, SOIC and SOIJ packages.
