| Description & Applications | I2C™Serial EEPROM Family Data Sheet 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. Features: • 128-bit through 1024 Kbit Devices • 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, I 2C™ 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 • 1 Million Erase/Write Cycles • Data Retention >200 years • 8-lead PDIP, SOIC, TSSOP and MSOP Packages • 5-lead SOT-23 Package (Most 1-16 Kbit Devices) • 8-lead 2x3mm and 5x6mm DFN Packages Available • Pb-Free and RoHS Compliant • Available for Extended Temperature Ranges: - Industrial (I): -40°C to +85°C - Automotive (E): -40°C to +125°C |
