Low-voltage design permits operation down to 1.7V (for 24AAXX devices), with standby and active currents of only 1 μA and 1 mA, respectively. Devices 1 Kbit and larger have page write capability. Parts having functional address lines allow connection of up to 8 devices on the same bus. The 24XX family is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP and MSOP packages. Most 128-bit through 16 Kbit devices are also available in the 5-lead SOT-23 package. DFN packages (2x3mm or 5x6mm) are also available. All packages are Pb-free (Matte Tin) finish. *24XX is used in this document as a generic part number for 24 series devices in this data sheet. 24XX64, for example, represents all voltages of the 64 Kbit device.

See Table 1-1, Device Selection Table, for details. Pins A0 and A1 are no-connects for the 24XX128 and 24XX256 MSOP devices. Pin 7 is “not used” for 24XX00, 24XX025 and 24C01C. © 2007 Microchip Technology Inc.
