24AA025/24LC025 is a 2 Kbit Serial Electrically
24AA024 1.7V-5.5V 400 kHz(1)
24AA025 1.7V-5.5V 400 kHz(1)

Erasable PROM with a voltage range of 1.7V to 5.5V.
The device is organized as a single block of 256 x 8-bit
memory with a 2-wire serial interface. Low current
design permits operation with typical standby and
active currents of only 1 μA and 1 mA, respectively.
The device has a page write capability for up to 16
bytes of data. Functional address lines allow the
connection of up to eight 24AA024/24LC024/
24AA025/24LC025 devices on the same bus for up to
16K bits of contiguous EEPROM memory. The device
is available in the standard 8-pin PDIP, 8-pin SOIC
(3.90 mm), TSSOP, 2x3 DFN and TDFN and MSOP
packages. The 24AA025/24LC025 is also available in
the 6-lead SOT-23 package.
