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 1.7V (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. Features: • 128-bit through 512 Kbit devices • Single supply with operation down to 1.7V for 24AAXX devices • Low-power CMOS technology: \- 1 mA active current, typical -1μA 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 • 100 kHz (1.7V) and 400 kHz (≥ 2.5V) compatibility • 1 MHz for 24FCXX products • 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
The 24AA256-I/MS is a 256kb (32k x 8) I²C™ CMOS serial Electrically Erasable PROM (EEPROM) capable of operation across a broad voltage range (1.7 to 5.5V). It has been developed for advanced, low-power applications such as personal communications or data acquisition. This device also has a page write capability of up to 64-byte of data. This device is capable of both random and sequential reads up to the 256k boundary. Functional address lines allow up to eight devices on the same bus, for up to 2Mb address space.
