AT24C01_14 Datasheet, PDF (3/14 Pages) ATMEL Corporation – Low Voltage and Standard Voltage Operation

AT24C01
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.
Pin Capacitance
Applicable over recommended operating range from T_A = 25°C, f = 1.0 MHz, V_CC = +1.8V.
