24C64 datasheet


FM24C64 is a 64Kbit CMOS non-volatile serial EEPROM organized as 8K x 8 bit memory. This device confirms to Extended IIC 2-wire protocol that allows accessing of memory in excess of 16Kbit on an IIC bus. This serial communication protocol uses a Clock signal (SCL) and a Data signal (SDA) to synchronously clock data between a master (e.g. a microcontroller) and a slave (EEPROM). FM24C64 is designed to minimize pin count and simplify PC board layout requirements.


1. Extended operating voltage: 2.5V to 5.5V
2. Up to 400 KHz clock frequency at 2.5V to 5.5V
3. Schmitt trigger inputs
4. 32 byte page write mode
5. Self timed write cycle (6ms typical)
6. Hardware Write Protection for the entire array
7. Endurance: up to 100K data changes
8. Data Retention: Greater than 40 years
