SLx 24C04
Pin Description
Serial Clock (SCL)
The SCL input is used to clock data into the device on the rising edge and to clock data out of the device on the falling edge.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer addresses, data or control information into the device or to transfer data out of the device. The output is open drain, performing a wired AND function with any number of other open drain or open collector devices. The SDA bus requires a pull-up resistor to VCC.
Write Protection (WP)
WP switched to VSS allows normal read/write operations.
WP switched to VCC protects the entire EEPROM against changes (hardware write protection).

SLx 24C04
The SLx 24C04 device is a serial electrically erasable and programmable read only memory (EEPROM), organized as 512 × 8 bit. The data memory is divided into 32 pages. The 16 bytes of a page can be programmed simultaneously.
The device conforms to the specification of the 2-wire serial I2C-Bus. Low voltage design permits operation down to 2.7 V with low active and standby currents.
The device operates at 5.0 V ± 10% with a maximum clock frequency of 400 kHz and at 2.7 ... 4.5 V with a maximum clock frequency of 100 kHz. The device is available as 5 V type (VCC = 4.5 … 5.5 V) with two temperature ranges for industrial and automotive applications and as 3 V type (VCC = 2.7 … 5.5 V) for industrial applications. The EEPROMs are mounted in eight-pin DIP and DSO packages or are also supplied as chips.

Bus Configuration
Master Device that initiates the transfer of data and provides the clock for both transmit and receive operations.
Slave Device addressed by the master, capable of receiving and transmitting data.
Transmitter The device with the SDA as output is defined as the transmitter. Due to the open drain characteristic of the SDA output the device applying a low level wins.
Receiver The device with the SDA as input is defined as the receiver.
