The CN24C32 is an industrial standard electrically erasable programmable read only memory (E2PROM) device that utilizes the industrial standard 2-wire interface for communications. The CN24C32 contains a memory array of 32K bits (4,096x8), which is organized in 32-byte per page. The E2PROM operates in a wide voltage range from 1.7V to 5.5V, which fits most application. The product provides low-power operations and low standby current. The CN24C32 is compatible to the standard 2-wire bus protocol. The simple bus consists of Serial Clock (SCL) and Serial Data (SDA) signals. The CN24C32 also has a Write Protect function via WP pin to cease from overwriting the data stored inside the memory array. In order to refrain the state machine from entering into a wrong state during power-up sequence or a power toggle on-off condition, a POR circuit is embedded. During power-up, the device does not respond to any instructions until the supply voltage (VCC) has reached an acceptable stable level above the reset threshold voltage. Once VCC drops below the POR threshold, the device is reset and enters into the Standby mode. This would also avoid any inadvertent Write operations during power-up stage. During power-down process, the device will enter into standby mode, once VCC drops below the POR threshold voltage. In addition, the device will be in standby mode after receiving the Stop command, provided that no internal write operation is in progress. Nevertheless, it is illegal to send a command unless the VCC is within its operating level.
