DS21210G-page 1 24AA024/24LC024/24AA025/24LC025 Device Selection Table Features • Single supply with operation from 1.8V to 5.5V • Low-power CMOS technology - 1 mA active current typical -1 µA standby current typical at 5.5V • Organized as a single block of 256 bytes (256 x 8) • Hardware write protection for entire array (24XX024) • 2-wire serial interface bus, I2C™ compatible • 100 kHz and 400 kHz clock compatibility • Page write buffer for up to 16 bytes • Self-timed write cycle (including auto-erase) • 10 ms max. write cycle time • Address lines allow up to eight devices on bus • 1,000,000 erase/write cycles • ESD protection > 4,000V • Data retention > 200 years • 8-pin PDIP, SOIC, TSSOP and MSOP packages • Available for extended temperature ranges - Industrial (I): -40°C to +85°C Pin Function Table Description The Microchip Technology Inc. 24AA024/24LC024/ 24AA025/24LC025 is a 2 Kbit Serial Electrically Erasable PROM with a voltage range of 1.8V 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 (150 mil), TSSOP and MSOP packages. Package Types Block Diagram Part Number VCC Range Max Clock Temp.
