N24C64
64 Kb I2C CMOS Serial
EEPROM
Description
The N24C64 is a 64 Kb CMOS Serial EEPROM device, organized
internally as 256 pages of 32 bytes each. This device supports the
Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C
protocol.
Data is written by providing a starting address, then loading 1 to 32
contiguous bytes into a Page Write Buffer, and then writing all data to
non−volatile memory in one internal write cycle. Data is read by
providing a starting address and then shifting out data serially while
automatically incrementing the internal address count.
External address pins make it possible to address up to eight
N24C64 devices on the same bus.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The DC input voltage on any pin should not be lower than −0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than −1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.
