24LC256 Datasheet

256K I 2 C CMOS Serial EEPROM


The Microchip Technology Inc. 24LC256 is a 32K x 8 (256 Kbit) Serial Electrically Erasable PROM, capable of operation across a broad voltage range (1.8V to 5.5V). It has been developed for advanced, low-power applications such as personal communications or data acquisition. This device 24LC256 also has a page write capability of up to 64 bytes 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 2 Mbit address space. This device is available in the standard 8-pin plastic DIP, SOIC, TSSOP, MSOP and DFN packages. 24LC256 Features • Low power CMOS technology- Maximum write current 3 mA at 5.5V- Maximum read current 400mA at 5.5V- Standby current 100 nA typical at 5.5V• 2-wire serial interface bus, I2C compatible• Cascadable for up to eight devices• Self-timed ERASE/WRITE cycle• 64-byte page-write mode available• 5 ms max write-cycle time• Hardware write protect for entire array• Schmitt trigger inputs for noise suppression• 100,000 erase/write cycles guaranteed• Electrostatic discharge protection > 4000V• Data retention > 200 years• 8-pin PDIP and SOIC (208 mil) packages
