The Microchip Technology Inc. 24AA32A/24LC32A is a 32Kb I2C™ compatible Serial EEPROM. The device is organized as a single block of 4K x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.7V, with standby and active currents of only 1 µA and 1 mA, respectively. It has been developed for advanced, lowpower applications such as personal communications or data acquisition. The 24XX32A also has a page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for up to 256 Kbits address space. The 24XX32A is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 DFN and MSOP packages.
Additional Features
Single supply with operation down to 2.5V for24LC32A devices
Low-power CMOS technology
2-wire serial interface, I2C™ compatible
Cascadable up to eight devices
Schmitt Trigger inputs for noise suppression
Output slope control to eliminate ground bounce
100 kHz and 400 kHz clock compatibility
More than 1 million erase/write cycles
Data retention > 200 years
