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. IYes 24AA024 1.7V-5.5V 400 kHz The device is organized as a single block of 256 x 8-bit (1) INo 24AA025 1.7V-5.5V 400 kHz memory with a 2-wire serial interface. Low current 24LC024 2.5V-5.5V 400 kHz I Yes design permits operation with typical standby and 24LC025 2.5V-5.5V 400 kHz I 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 for is available in the standard 8-pin PDIP, 8-pin SOIC 24AA024/24AA025 devices, 2.5V for 24LC024/ (3.90 mm), TSSOP, 2x3 DFN and TDFN and MSOP 24LC025 devices packages.
