Description:
• 128-bit through 1024 Kbit Devices
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 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 Pb-free (Matte Tin) finish.
• Single Supply with Operation Down to 1.7V for
24AAXX Devices
• Low-Power CMOS Technology:
- 1 mA active current, typical
- 1 μA standby current, typical (I-temp)
• 2-Wire Serial Interface Bus, I2C™ Compatible
• Schmitt Trigger Inputs for Noise Suppression
• Output Slope Control to Eliminate Ground Bounce
• 400 kHz (≥ 2.5V): 24LCXX and 24AAXX
• 1 MHz (≥ 2.5V) and 400 kHz (1.7V): 24FCXX
• Self-Timed Write Cycle (including Auto-Erase)
• Page Write Buffer
• Hardware Write-Protect Available on Most
Devices
• Factory Programming (QTP) Available
• ESD Protection >4,000V
Note:
This document is an overview. For

*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.
• Pb-Free and RoHS Compliant
• Available for Extended Temperature Ranges:
- Industrial (I): -40°C to +85°C
- Automotive (E): -40°C to +125°C
