I think you can replace it with a 24C64 if you have a 5V design and the I2C clock is max. 100kHz. Please refer to the datasheet: 24LC64 works from 2.5V - 5.5V @ 400kHz, while 24C64 works from 4.5V - 5.5V @ 100kHz

My design work whit 5 v power suplies. The 24C64, work at 400 Khz on 5v. (• Internally Organized 4096 x 8, 8192 x 8 • 2-Wire Serial Interface • Schmitt Trigger, Filtered Inputs for Noise Suppression • Bidirectional Data Transfer Protocol • 100 kHz (1.8V, 2.5V, 2.7V) and 400 kHz (5V) Clock Rate) I see the Microchip site, the 24c64 is old, not in production. The replacement is 24LC64. **broken link removed**
