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.

Device/Page Addresses

The ACE24C16A does not use the device address pins, which limits the number of devices on a

single bus to one.

Write Protect (WP):

The ACE24C16A 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.
