Description:
The Microchip Technology Inc. 24CXX, 24LCXX,
24AAXX and 24FCXX (24XX*) devices are a family of
128-bit through 512 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 1.8V (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 pack-
ages. 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 available in a Pb-free (Matte Tin) finish.

Note 1:
Pins A0, A1, A2 and WP are not used by some
devices (no internal connections). 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.

*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.

As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.

This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance™ Model, which can be obtained from Microchip’s web site:
