5 / 26 page 5/26 M24C64, M24C32 SIGNAL DESCRIPTION Serial Clock (SCL). This input signal is used to strobe all data in and out of the device. In applica- tions where this signal is used by slave devices to synchronize the bus to a slower clock, the bus master must have an open drain output, and a pull-up resistor must be connected from Serial Clock (SCL) to VCC. (Figure 4. indicates how the value of the pull-up resistor can be calculated). In most applications, though, this method of synchro- nization is not employed, and so the pull-up resis- tor is not necessary, provided that the bus master has a push-pull (rather than open drain) output. Serial Data (SDA). This bi-directional signal is used to transfer data in or out of the device. It is an open drain output that may be wire-OR’ed with other open drain or open collector signals on the bus. A pull up resistor must be connected from Se- rial Data (SDA) to VCC. (Figure 4. indicates how the value of the pull-up resistor can be calculated). Chip Enable (E0, E1, E2). These input signals are used to set the value that is to be looked for on the three least significant bits (b3, b2, b1) of the 7- bit Device Select Code. These inputs must be tied to VCC or VSS, to establish the Device Select Code. Write Control (WC). This input signal is useful for protecting the entire contents of the memory from inadvertent write operations. Write opera- tions are disabled to the entire memory array when Write Control (WC) is driven High. When uncon- nected, the signal is internally read as VIL, and Write operations are allowed. When Write Control (WC) is driven High, Device Select and Address bytes are acknowledged, Data bytes are not acknowledged. Figure 4.
