Its low-voltage 2 C Compatible Two-Wire Serial Interface, I design permits operation down to 1.7V, with standby Cascadable up to Four Devices and active currents of 5 A and 5 mA, respectively. The Schmitt Trigger Inputs for Noise Suppression 24XX1025 also has a page write capability for up to 128 bytes of data. Output Slope Control to Eliminate Ground Bounce 100 KHz and 400 KHz Clock Compatibility This device is capable of both random and sequential 1 MHz Clock for FC Versions reads. Reads may be sequential within address boundaries 0000h to FFFFh and 10000h to 1FFFFh. Page Write Time: 5 ms, Maximum Functional address lines allow up to four devices on the Self-Timed Erase/Write Cycle same data bus. This allows for up to 4 Mbits total 128-Byte Page Write Buffer system EEPROM memory.
