Description:The Microchip Technology Inc. 24CXX, 24LCXX, 24AAXX and 24FCXX (24XX*) devices are a family of 128-bit through 1024 Kbit Electrically Erased PROMs.
The devices are organized in blocks of x8-bit memory with 2-wire serial interfaces.
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.
