Device Selection Table:
Part Number 24AA1025 24LC1025 24FC1025

VCC Range 1.7-5.5V 2.5-5.5V 2.5-5.5V

Max. Clock Frequency 400 kHz 400 kHz* 1 MHz

Temp Ranges I I, E I

This device is capable of both random and sequential reads. Reads may be sequential within address boundaries 0000h to FFFFh and 10000h to 1FFFFh. Functional address lines allow up to four devices on the same data bus. This allows for up to 4 Mbits total system EEPROM memory. This device is available in the standard 8-pin PDIP and SOIJ packages.

100 kHz for VCC < 2.5V. *100 kHz for VCC < 4.5V, E-temp.
