The Microchip Technology Inc. 24AA024/24LC024/

Range Protect

24AA025/24LC025 is a 2 Kbit Serial Electrically

24AA024 1.7V-5.5V 400 kHz⁽¹⁾

24AA025 1.7V-5.5V 400 kHz⁽¹⁾

Yes

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 MSOP packages.

24LC025 2.5V-5.5V

400 kHz

Yes

Note 1: 100 kHz for VCC < 2.5V

Features:

• Single supply with operation from 1.7V to 5.5V for

24AA024/24AA025 devices, 2.5V for 24LC024/

24LC025 devices

• Low-power CMOS technology:
