24AA024/24LC024/24AA025/24LC025 2 2K I C Serial EEPROM Device Selection Table Description: Part VCC Max Temp. Write The Microchip Technology Inc. 24AA024/24LC024/ Number Range Clock Range Protect 24AA025/24LC025 is a 2 Kbit Serial Electrically (1) Erasable PROM with a voltage range of 1.7V to 5.5V. 24AA024 1.7V-5.5V 400 kHz IYes The device is organized as a single block of 256 x 8-bit (1) 24AA025 1.7V-5.5V 400 kHz INo memory with a 2-wire serial interface. Low current 24LC024 2.5V-5.5V 400 kHz I, E Yes design permits operation with typical standby and 24LC025 2.5V-5.5V 400 kHz I, E No active currents of only 1 A and 1 mA, respectively. The device has a page write capability for up to 16 Note 1: 100 kHz for VCC < 2.5V bytes of data. Functional address lines allow the connection of up to eight 24AA024/24LC024/ Features: 24AA025/24LC025 devices on the same bus for up to 16K bits of contiguous EEPROM memory. The device Single Supply with Operation from 1.7V to 5.5V is available in the standard 8-pin PDIP, 8-pin SOIC for 24AA024/24AA025 Devices, 2.5V for (3.90 mm), TSSOP, 2x3 DFN and TDFN and MSOP 24LC024/24LC025 Devices packages.
