Description

The AT24C01 provides 1024 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 128 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24C01 is available in space saving 8-pin PDIP, 8-pin MSOP, 8-pin TSSOP, and 8-pin JEDEC SOIC packages and is accessed via a 2-wire serial interface. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), 2.5V (2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

Pin Description

SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device.

SERIAL DATA (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be wire-ORed with any number of other open-drain or open collector devices.

Memory Organization

AT24C01, 1K SERIAL EEPROM: Internally organized with 128 pages of 1 byte each. The 1K requires a 7-bit data word address for random word addressing.
