SLx 24C04/P
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 V_CC.
Write Protection (WP)
WP switched to V_SS allows normal read/write operations.
WP switched to V_CC protects the entire EEPROM against changes (hardware write
protection).
Additionally write protection is managed by a protection bit associated to each page.
