24AA512/24LC512/24FC512
(24XX512*)
is
a
64K x 8 (512 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 and data acquisition. This device also
has a page write capability of up to 128 bytes of data.
This device is capable of both random and sequential
reads up to the 512K boundary. Functional address
lines allow up to eight devices on the same bus, for up
to 4 Mbit address space. This device is available in the
standard 8-pin PDIP, SOIJ, SOIC, TSSOP, DFN and
14-lead TSSOP packages. The 24AA512 is also
available in the 8-lead Chip Scale package.
100 kHz for VCC < 2.5V
400 kHz for VCC < 2.5V
