3 / 20 page ACE24C256C Two-wire serial EEPROM VER 1.2 3 Block Diagram Pin Descriptions Serial Clock (SCL): The SCL input is used to positive-edge clock data in 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. Device Addresses (E2, E1, E0): The E2, E1, and E0 pins are device address inputs. Typically, the E2, E1, and E0 pins are for hardware addressing and a total of 8 devices can be connected on a single bus system. If these pins are left floating, the E2, E1, and E0 pins will be internally pulled down to GND. Write Control (WCB): The Write Control input, when WCB is connected directly to V CC, all write operations to the memory are inhibited. When connected to GND, allows normal write operations. If the pin is left floating, the WCB pin will be internally pulled down to GND. Pin Capacitance Test Conditions: TA = 25°C, F = 1MHz, VCC = 5.0V. Symbol Parameter Max Units Test Condition CI/O Input/Output Capacitance (SDA) 8 pF VI/O=GND CIN Input Capacitance (E0,E1,E2,WCB,SCL) 6 pF VIN=GND |
