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 bi-directional 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.
Write Protect (WP):
The ACE24C02A has a Write Protect pin that provides hardware data protection. The Write Protect pin allows
normal read/write operations when connected to ground (GND). When the Write Protect pin is conceded to Vcc
the write protection feature is enabled.
